Debating an s6 4.2L swap...

[JumboBlack1.8]

As the title states, I'm debating moving on from my built 2L motor and going with a mildly powered s6 motor. I've read all of the motor swap threads out there, but nearly all of yuem are incomplete, especially when it comes to a parts list....

I've got the gist of what needs to be done (grinding pats of the upper oil pan for clearancing, rad support fabrication, minor engine harness adaption to mate to OEM connectors, etc etc).......but does anyone out there have a more comprehensive list of steps and parts? I haven't had a problem sourcing engines, harnesses, or ECUs, but I'd at least like an idea of what I'm getting in to before I start buying stuff...

Also, I've posted a feeder for my current 400+whp setup. Check the classifieds

[Mad Cow]

AFAIK the S6 block simply won't fit because the bellhousing is too long and the intake manifold is too tall to fit under the hood. There was a picture of a half-completed swap in one of Siena's threads and it's clear that it won't fit without a ton of work.

EDIT: I was thinking of the RS6 motor, this thread: http://www.ozaudi.com/forums/showthread.php/22760-Audi-V8-Into-B5-A4-The-Facts.

[JumboBlack1.8]

Haha. No worries. Had me nervous for a second

[flynnr]

why? what is the benefit of going NA? you can get as much hp out of a 2871 as the v8 will offer, while being lighter at the same time.

[JumboBlack1.8]

I don't care much for the high horsepower anymore......I'm looking for something NA, with less moving parts, that still has some grunt to it.....Plus, it'll be a unique car that I won't have to constantly be tuning........I just don't have the time to keep up with this motor/tune anymore

[biketsai]

Justin, have you thought about ditching the Maestro setup? or even paying some tuner to help you get it right with a few hours?

I am really eye'in your block!

[JumboBlack1.8]

Yea, I've thought of taking it over to Vast, and having them work their magic......it's still an option, if the S6 motor project proves to be too much for me. I'm still doing a bunch of research at the moment, so this may, in fact, never come to fruition......but I'm leaning quite heavily towards doing it.

[Corrado_Guy]

The swap part isn't too bad, check out MotorGeek as there are a lot of threads about this topic. The biggest issue is the electronics, most V8 motors are attached to automatic transmissions and this is really hard to swap over if you want to have a manual. The immobilizer is a problem as well but I think this can be removed with a chip but you would want to check on this. Most people tend to swap the physical motor and then use stand-alone to make it run. If you have emissions testing where you live this may be a problem.

[JumboBlack1.8]

I've just found this thread over in the C5 Section:
http://www.audizine.com/forum/showthread.php/371810-JHM-C5-A6-S6-4.2-Development/page2?highlight=manual+swap

Evidently, the Euro version of the S6 and S8 came with a manual transmission. Both Vast and JHM offer the European file. According to that thread, JHM is also developing (or already has?) an aggressive tune based off of that OEM European S6/S8 file.......The standard C5 4.2 presents a few more hurdles, since they didn't come from the factory with a manual transmission on either side of the pond. This is one of the reasons why I've chosen the S6 motor over the standard A6 V8 motor

The only things I'm concerned about, at the moment, are flywheel options and cooling. I'm not sure what I want to do with my radiator fan setup, and how to tie that into the OEM ECU.

[revolution337]

I'm actually taking on this swap. I recently aquired a 4.2 from an 02 A6, along with the harness and ECU. And from what I've read (haven't checked myself) the engine I have (code AWN) actually weighs LESS than an AEB, mostly due to the aluminum block. I've been wanting to do this swap for the same reasons you do, less complications being NA, plus it'd be really unique. Cost wise, its cheaper than the BT build I had originally planned too. As stated above, the biggest problem I forsee is the fact that the engine came from an auto, and I plan on running my 01A with the motor. I will deal with that problem later down the road though.

I'd say go for it. Then we can bounce ideas off each other [up]

[JumboBlack1.8]

Shoot an email over to a JHM sales rep. They can do an immoblizer defeat, so the engine will run flawlessly with a manual configuration. They've taken a tremendous interest in the 4.2 V8 market

Awesome info! I'll have to do that!

As for the cooling situation, what I'm doing is deleting the stock viscous fan and adding electric fans in FRONT of the radiator (trimming the bumper of course). Not sure as to how I'm working that into the stock ECU yet though. The best idea I have for the radiator is just flipping my stock one upside down (inlet/outlet on the passenger side) and make some custom plumbing.

Wow, that makes me want to do a V8 swap. [drool]

[TConklin821]

I don't know much about it, but I say do it. Why?

BECAUSE RACE CAR.

Okay, seriously though. I would take a nice, powerful V8 NA over a Turbo I4 any day. The sound of the 4.2 with the right exhaust is pure sex.

When you put it this way, why not ditch the B5 and go for a B6 S4?

[ZimbutheMonkey]

Not sure if you're parting out the motor, but the intake cam and valve springs/retainers are tempting.

[revolution337]

because the B5 is way better looking than a B6 (I'm a little biased [:p]) plus its more unique

I'm considering picking up a v8 a6 and doing this. I've followed all the build threads on here, siena, the russian etc... and I only have one problem. I'm not the greatest at wiring and custom tuning yet, so a full harness and v8 ecu would allow me to make the swap look oem. Plus then I could get a free apr tune from work [:D]

This is exactly what I plan on doing. I'm want to make it so that its like the engine came in the vehicle from the factory. Full OBD functions, functional cluster, no CEL, passing emissions (this is going to be the tough part), DD-able, etc.

/ thread :)

haha. seriously though, with the money and TIME it would take to do this, you would be better off finding a cheap b6 s4...

not to mention, the moving parts thing... i would think that the s4 would have a lot more moving parts... think - twice as many cams, pistons, valves, exhaust mani's, gaskets, seals, places for leaks, etc.

if you arent looking for high horsepower, and want NA, why not just buy a 2.8 b5 a4???

[revolution337]

[JumboBlack1.8]

Just curious, what are the complications with the automatic motor? Will you have the same issue with the crank? If so, hopefully shaving it and adding a pilot bearing would help.

There aren't very many (if any) mechanical complications that I've found in my research......AFAIK, the 40v motor doesn't have an exceeding short crank like the automatic cranks found in our motor. The only issue is finding a flywheel with the correct bolt pattern (I believe its a 10-bolt configuration)....and modifying the B5 S4 transmissions/engine adapter plate to a 5speed tranny

[JumboBlack1.8]

I don't see how everyone imagines that this will be a bank-account shattering build......It'll be SIGNIFICANTLY less that the original cost of building my current motor.....The only things I need to buy are the engine, harness, ecu, motor mounts, clutch (might use my current one), correct fly wheel, new radiator fans, engine adapter plate, a tune from JHM or Vast, and some other odds and ends......I can't imagine it costing more than $4k. A ton of people (yourselves included) dump far more money into a standard BT build.

As far as buying a B6 S4 goes......I've spent a good amount of time in that forum, and I simply do NOT trust the reliability of that motor.....There are too many instances of them failing from normal use. I no longer have even the slightest interest in owning one

This interests me because i was talking to my friend about this swap when i first got my b5 avant... he kinda shot me down so, now I feel revived... But a 5 speed tranny huh? why not the 6?

[beemercer]

Cool thread, very interested in seeing this develop. OP where in Boston are you?

As far as the swap I'd go with an S8 motor if you can find one, otherwise an S6 motor. I'd avoid the A6 4.2.

Since you'll most likely be using a manual its best to flash in a stock Euro S6 file. It is floating around (nefmoto I believe) and there are instructions on how to flash it (contact rednecktruck, he did his recently). That will get you running for free. If you are inclined a file like whats in my car at the moment will really liven the car up. I would forgo the VAST tune, the man who wrote that tune now writes for JHM and the JHM version is far more updated. My next revision should have SAI delete, cat delete, rear O2 delete and launch control, plus its significantly faster and sharper on throttle response.

The reason I say to go with the S6/S8 motors over the A6/A8 4.2 is mostly the cams and how the intake manifold works. The IM stages are operated via a vacuum solenoid that opens when the ECU tells it to, the issue is that the 3 and 2 stage IMs open at different times. Since the only factory manual tune is for the S6 its best to try and keep your setup as similar to that motor. Tuning off the automatic file is fruitless.

As far as driveline the A6 01e bolts onto the motor and only requires a bit of clearance around the starter iirc (redneck truck has a whole manual swap writeup in his signature for an A6 4.2, it will outline setting the driveline up). The 2.7TT flywheels and clutches work directly on the motor, mine has a VAST LWFW and Stg4 clutch.


When you put it this way, why not ditch the B5 and go for a B6 S4?

The B6 S4 motors are a disaster in a lot of ways compared to the other V8s.
-Timing System: timing belt motors have the simplicity of a timing belt and standard accessories, which drops the cost of servicing both; the BHFs have chain driven accessories and a difficult to service timing system (some work can be done with the motor in the car, more indepth work requires the motor to come out)
-Rods: the S6/S8 motors have forged rods similar to the older 32v 4.2 motors, the A6/A8 4.2s have essentially the same rods as a 2.7TT, the FSI V8s have forged rods, the BHF has thin powdered metal rods with a tapered wrist pin (can handle ~450whp max)
-Pistons: iirc all the 40v 4.2s have cast pistons, the fsi motors have forged pistons
-Block Construction: The timing belt motors are lower silicon with chemically stripped bores, the timing chain motors have a higher silicon content and mechanically stripped bores. The issue is that the higher silicon content causes the block to expand slower, but since the piston metallurgy wasn't changed the pistons expand at the same rate and contact the cylinder walls (very small tolerances in the Alusil motors) causing the unfortunately typical cylinder wall scoring in the B6/B7 S4s
-Cams: The S8 cams have the same lobe design as the S4, the S6 apparently has an S8 intake and A6 exhaust cam, the A6 has both cams low lift. So if you have an S8 cam set theres no difference
-Intake Manifold: The S6/S8 intake manifold has the best multistage design for the V8 motors. The S4 IM drops a flap right in front of the TB and doesn't seal the long runners when it switches to the short runner. The A6/A8 manifold is a disaster, 3 stages and both flaps move right in front of the TB
-Exhaust manifold: The S6/S8/Early A6/A8 manifolds have a bigger outlet and 4 separate runners, the later A6/A8/S4 manifolds have a shared runner and smaller outlet


The biggest issue with the S4 motors is the cylinder wall scoring, and since most of the cars are gonna have some good miles on them you can't really take the necessary steps to ensure it doesn't happen (remove the precats, very diligent oil change intervals).

[biketsai]

^ Great info. I definitely did not know there was that big of a difference between the V8 motors.

[JumboBlack1.8]

Beemercer.....Thanks for all that info! I wasn't aware that there was a difference between the S6 and S8 motors.

I live in Brighton, but I do all my work at my parents' house in Milton.

I'd love to get the ball rolling on this ASAP.....I will keep this thread updated as I get closer to making a decision

[JumboBlack1.8]

Anyone know of any S8 part outs?? I'm having a hard time finding a motor......I got a BUNCH of emails from junkyards about S6 motors.....but I have yet to source an S8 setup

I heard from that guy yesterday afternoon....apparently that motor is sold. He's got some other S8 engines, but his prices for everything (motor, harness, ecu, cluster, etc) are a bit higher than I'd like to pay.....Not to mention the $300 core fee...

I also contacted Shokan, but they're prices were outrageous......$4500 + $350 shipping for a BARE longblock....no manifolds, accessories, or anything.....just the shortblock and heads......No thanks

Looks like I'll need to be a bit more patient in my search.......damn

[beemercer]

If you can get an S6 motor cheap I'd go that route. I don't think the exhaust cam will make a massive difference. Take the money saved and get a lightweight crank pulley/lwfw/more aggressive tune, you'll love how snappy and responsive it is.

Whats the plan for exhaust, keeping the stock exhaust manifolds?

[JumboBlack1.8]

The best price on an S6 motor was $1950 shipped included everything (all accessories, harness, cluster, ecu)....but I'm trying to get them to send me a picture of it before I agree to buy it. I've also asked these same people to source an S8 motor, but I haven't gotten a response since early Friday afternoon.....Hopefully they'll get back to me some time soon

As for the exhaust....I'm keeping the stock exhaust manifolds, but I"m torn between running Piggie Pipes, or forking over some extra coin for some proper DPs with high flow cats.....The JHM headers are way out of the budget, and I'm assuming they won't even fit between the B5 frame rails......Then, I've gotta find a decent exhaust shop that can fab up decent catback.

I'll definitely be getting at LEAST a lightweight flywheel. MIGHT look into the lightweight crank pulley as well. Was thinking of keeping my Spec Stg3+ clutch....I've grown pretty fond of it, and it's still got plenty of meat left.

[revolution337]

If that deal on the S6 motor is legit, I'd definitely go that route. That's a damn good price for everything shipped. Kinda makes me wish I would have looked around a little more before I purchased my engine.

Damn, $2k for everything [o_o]... I'd have trouble passing on that.

For exhaust I'd go for 2.5" downpipes with cats downstream. The S6 will have the bigger exhaust manifolds and should have a decent amount of headroom over what pippie pipes will flow. Typically its 350whp for the stock smaller exhaust manifolds and 300whp for piggie pipes before they start choking the motor off. For the catback 2.5" with an x-pipe is your best bet.

Well how much power does the S6 motor put out with piggies? Does it even need them?
All this V8 talk actually has me interested.

[beemercer]

Well how much power does the S6 motor put out with piggies? Does it even need them?
All this V8 talk actually has me interested.

Piggies, JHM 93 tune and a good catback should be up around 300whp. My B6 S4 was 328whp/300wtq on a mustang with a ported intake manifold (a wash compared to the S6 manifold), catless 2.5" Milltek downpipes (2.5" is key, better option than piggies so some extra power there), 2.5" X-pipe catback and JHM 93 tune.

So looking at the differences between the two (my S4, S6 4.2 with piggies/catback/tune)
Intake Tract - No advantage: Should be the same, S6 has 3 inlets same with 05 S4s, same MAF and TB, similar inlet piping
Intake Manifold - No advantage: Single flap ported vs dual flap stock porting, doubt one flows better than the other
Heads - No advantage
Compression - No advantage: Both 11.0:1
Displacement - Slight advantage to the S6: 0.6cid more due to 93mm stroke vs 92.8mm
Cams - Slight Advantage to the S4: Bigger exhaust cam
Exhaust Manifold - Advantage to the S6
Downpipes - Advantage to the S4
Catback - No advantage
Tune - No advantage: Same tuning mostly, iirc the S4 can do a bit more with the cam phasing but I'm not positive


Just looking through it I don't see a healthy piggie/tune/catback S6 4.2 making less than 300whp. The S6 actually doesn't have precats iirc, but are the stock downpipes gonna fit in a B5?


For everyone interested in 4.2s, the general rules for making good N/A power:
-No precats
-2.5" exhaust piping
-X-pipe
-Need a good tune to extract the power, the only people doing good tunes is JHM. Their calibrator works for SVT and recently helped on the Coyote 5.0 V8s and we all know how those turned out (my point being he knows how to tune N/A cars, not many Audi tuners do). If you go standalone then its obviously a different issue

[beemercer]

hows the tranny in it? If its good I'd buy it, turn the tranny to someone with a busted one (the 4.2 auto trans are garbage), get an 01e and go from there. I need some odds and ends from a 4.2 part car so I think you should buy it so I can get my parts lol

Actually I work with a couple ex-audi techs, (they found out that VW was hiring in their desired city so they moved over) and from what they have been telling me, the auto trans isn't a piece of junk at all. Neither had seen many come in for repairs in either of there 5+ years at Audi.

[beemercer]

the number of 4.2 A6 owners I've talked to that have replaced transmissions/torque converters is much higher than any other platform.. granted its due to poor maintenance habits but the other autos hold up better.

[JumboBlack1.8]

What do you think would be a good price to pay for a complete 2001 S8 setup? Harness, accessories, and ecu all included........Just got a quote from a local (Force5Auto), and I'd LOVE to not have to deal with shipping (plus, I have yet to see ANY physical evidence of any of the motors in the quotes I've gotten).......I've set a strict budget, and I'd like to not go over it.....but I don't wanna lowball the guy.....Was REALLY hoping to get everything for under $3k, on the high end.......Is that unreasonable?

[revolution337]

I think its reasonable to ask 2500-2750 for all of it. Do you know the mileage of the engine?

[JumboBlack1.8]

Found a 2001 s8 motor with 25k original miles......They want $3200 shipped for everything......that's more than I wanted to spend, but I'm VERY enticed by the low usage....

*EDIT*

Contrary to what was posted on the previous page, the S8 crank has an 8-bolt pattern, NOT 10-bolt
http://audipages.com/tozo/crank.JPG

[beemercer]

yeah older V8s and the RS6 are a 10 bolt, the rest are 8 bolt and the standard flywheels go right on. I'd buy that motor personally, see if they can run a compression test on it for some piece of mind

[JumboBlack1.8]

I'm gonna try to get them down to $3k shipped. And I'll see about them running a compression test for me. Also waiting to see if we're on the same page about the motor being "complete".

[beemercer]

Haha, probably a solid idea to agree on what complete is haha

[NeedingAnAudi]

3k for everything? Sounds good to me

[JumboBlack1.8]

Update.....I'm having some second thoughts about ordering motors from places on Car-part.com or other online salvage yard resources.....I've been reading a fair amount of reviews from people who've have bad experiences, so I've begun to grow paranoid of trusting a company I've never had any prior experience with.

So, that being said, I've found a motor at Force5 Auto in Concord, NH, which is relatively local to me. The motor is from an 01 S8 and includes everything for $3k. But, the mileage is high, at 128k.......That's MUCH higher than I wanted, but the engine has been tested, and has a warranty. Also, Chris Semple is a very well known and trusted guy in the local community, so I have faith that the engine will be as good as he says it is. Think I'm gonna try to strike a deal with him some time next week!

[beemercer]

if you can pull the valve covers to get an idea of the oil history, compression test and maybe borescope the cylinders I'd have no worries about buying a higher mileage timing belt 4.2 nothing really fails internally. My A6 has 156k miles and still runs very strong.

[JumboBlack1.8]

^^Any idea who I can contact at JHM about getting the tweaked Euro S8 file? I'm hoping to complete this swap in 2 weeks.......Also, would love to know where to get some 2.5" downpipes for a reasonable price? I've PM'd Greg@Griffin to see if the Milltek Group Buy is still on

Any info you can get on a tune for the engine or downpipe (well, any good info about the swap for that matter), if you wouldn't mind sharing this info with me I'd appreciate it. I've been looking around for places to get a tune for this engine and I haven't had much success yet.

^^Awesome man! Have you decided what you're going to do with it???

Also, just wanted to update this thread, as I've found some very important information in my research.......Evidently, I'll need to use the A6 V8 upper and lower motor mount brackets to get the motor to fit in the OEM location, without any fabrication.....the S8 engine has different engine mount points than the standard a6 v8 motor. While the mounting points on the block surface are the same, the upper and lower engine mount brackets are slightly different. The passenger side mounts is an easy swap......but on the driver's side, the S8 oil filter housing (which is a completely different design than the A6.....not exactly sure why) is integrated into the motor mount bracket.....So, I'll be picking up a new set of motor mount brackets AND an A6 oil filter housing.......Hopefully then, the motor will drop right in

The hard part is going to be finding a solution for the FRONT engine mount (it's a torque mount on the PS that bolts to the frame rail.......it essentially replaces the snub mount).....I'll likely have to fab up something.......somehow....

Should be picking up the engine this week! I'll post pics as I get them

^^ excellent idea. I forgot that russian did that, and it looks like it could be easily reversible if anyone wants to go back to a 1.8

[capea4]

Not only am i right down the street from you (rt 3), but i also have both a B5 A4 and a D2 S8. Someday that motor will be swapped, wating for a tourist to take out the S, maybe next summer. I can tell you that the S8 4.2 is bye far the greatest v8 i have ever owned, even in the D2 it gets up good.

Maybe its just the pictures, but that looks somewhat flimsy to me....But I'll see if I can come up with something similar with my VERY limited fabrication skills[headbang]

Hoping to pick up the engine and motor mount brackets in the next day or so......2.0T motor is coming out tomorrow [wrench].....Still waiting to hear about a set of Milltek catless downpipes...THEN, all I should theoretically have to do is source an S4 lwfw, and some dual 12" radiator fans (thinking of getting 2 SPAL pusher fans....one that will always stay on, and another that'll be tied into the radiator fan switch....still not sure).

email [email protected], I already gave their calibrator a heads up about your build. You should be able to get the same file as me as long as there are no issues with A6 vs S8 ecus. Should be sai delete, cat delete, rear O2 sensor delete and possibly launch assist if he finished it up. I'm still waiting for my new chip. You'll need to send in the ecu to have a riser board soldered on.

the oil filter should be on the passenger side for the A6 mounts.. a few things about that, make absolutely sure you replace the coolant pipe down by the bracket. The stock plastic piece fails and its a motor out deal. Bufkin Engineering makes a billet replacement with viton o-rings.. iirc scott@advanced has a few. This goes for anyone thinking of a timing belt 4.2.

also if you are so inclined JHM can set you up with an oil filter relocation kit like I have on my A6 (to clear the headers), For that email sales@jhmotorsports and ask for the part number of the filter kit (mine was for a rustang and uses old 5.0 oil filters) and if they can make you a new washer. If you go for it, I'd use AN fittings and stainless braided and you can easily add an oil cooler.

for the front motor mount I've been meaning to get a GM trans mount and adapt that to my car. the stock mount sheared and if I put in a new one the same thing will happen again.

[JumboBlack1.8]

Do you have a link for the billet coolant flange? I can't seem to find it.

Chris @ Force5Auto has gone M.I.A......I've called, left voicemails and emails.....but nada.....Gonna wait another day, then (hopefully) start sourcing another motor.......the time is ticking.....I'm moving in 3 weeks, and I could REALLY use a running car, lol

[flynnr]

not to be a debbie downer, but do you really think that you will be able to get this goin before you move? that seems like a huge task to me... 3 weeks to do something that not a ton of people have done before, and you said you have limited fabrication skills, which would probably be helpful.

I would LOVE to see this thing going, but would honestly recommend just waiting until after you move so you arent stuck in the middle of a project of this magnitude.

in for sound clips of this beast!

[JumboBlack1.8]

^HAHA....I know.....no need to remind me, lol....It was a terribly stupid decision. But I made up my mind a few days before getting a call with a job offer. Fortunately, I'm only moving about 1.5hrs away, so I could return to my parents' house on weekends to finish it up. If I can't meet my deadline, I'll have to rent a VERY cheap car for a week or two.....no big deal

[Scotty@Advanced]

The only things I'm concerned about, at the moment, are flywheel options and cooling. I'm not sure what I want to do with my radiator fan setup, and how to tie that into the OEM ECU.
You have 2 options for flywheels. Use 2.7 stuff and have an engine/transmission package that is 5/8inches longer, use 30V v6 flywheel and clutch or use Euro S6/S8 flywheel and clutch. I guess that is 3 options.


I'm actually taking on this swap. I recently aquired a 4.2 from an 02 A6, along with the harness and ECU. And from what I've read (haven't checked myself) the engine I have (code AWN) actually weighs LESS than an AEB, mostly due to the aluminum block. I've been wanting to do this swap for the same reasons you do, less complications being NA, plus it'd be really unique. Cost wise, its cheaper than the BT build I had originally planned too. As stated above, the biggest problem I forsee is the fact that the engine came from an auto, and I plan on running my 01A with the motor. I will deal with that problem later down the road though.

I'd say go for it. Then we can bounce ideas off each other [up]

The 40V V8 weighs about 80 pounds more than the 1.8t.

[JumboBlack1.8]

I've JUST purchased a Spec single mass LWFW from a B5 S4.....according to my research (and speaking with others), a transmission adapter plate is NOT necessary in this swap if you choose a shorter, single mass unit over a dual mass. This will allow for MUCH needed space in the front of the engine for your radiator fans

That doesn't sound right, all the spec 2.7tt flywheels i've seen are the same dims as stock.

[beemercer]

my VAST LWFW needs the spacer plate fwiw.

And yes thats the coolant pipe, I had thought I had the page bookmarked.

For the A/C delete could you leave a bracket with the pulley still on it? I gather its to save space? Or just go to napa or somewhere and grab a bunch of belts and try to wrap them and if they dont fit return them

[Capt. Obvious]

For the deleted AC, the best way to figure out how long of a belt you'll need is to use a piece of string. Just run the string along the path of the belts and hold the tensioner(s) roughly in the spot they will be with the belt and see how long the string is. Then go the auto parts store and get a belt that long.

Great call. Thanks!

As for the adapter, I'll pick one up from DxC (big in the S4 forum....he's local to me), just in case. According to others, the engine will line up perfectly with OEM A6 V8 upper and lower engine mounts WITH an adapter plate. I'm planning on running Push radiator fans in front of the radiator, so hopefully spacing won't be too much of an issue

[capea4]

is that just the long blocks, or turbo included?
plus FMIC, not much but it all adds up.

Like I said, I never actually checked myself so I wasn't sure. But thanks for the info!

And what exactly do you mean that the engine/trans package will be 5/8" longer with 2.7 stuff? Are you saying I will need a adapter plate, or just that compared to the 1.8 setup, this will be 5/8" longer.

[NeedingAnAudi]

I've been doing some very crude measurements. The 1.8 trans to the end of the belt is around 20". The 2000 A6 4.2 I have appears to be around 21". So, with my Audi cross-breeding juices flowing, I think that if i can get the v8 to bolt directly to the 5-speed trans, the only modifications needed are front engine mount, and cutting out the fans and putting in pusher fans.

This excites me to no end! Just need to get over my wiring fears and I might have a v8 a4 finally.

From what I knew all 99.5's are DBC, but for all I know really late ones might have been DBW.

I can't see any way of making the V8 work with DBC short of using the 32v ecu and TB though, and that's a pretty hacky solution.

[JumboBlack1.8]

Positive that 99.5 was DBC. 2000 was the only "bastard child" motor with an 058 block, small port head, and DBW. If you have a pre '00 motor, you'll need a DBC a6 motor

Yup the 99.5 had an AEB, which was DBC. Early 2000's also had the AEB which was DBC. The ATW engine is essentially a DBW AEB, then late 2000 had the AWM which was the 06A block and DBW.

If you install the appropriate wiriing DBC/DBW doesn't matter, however it's much easier to start with a DBW car and use a DBW engine.

All 40V v8's were DBW and it's impossible to convert them to DBC unless you go standalone, which adds $3-$4K to your build.

If you want a DBC engine then look for a 32V engine from an A8.

But then I can't say "yeah I got 40 valves." lol Actually Somebody5788 said the 99.5s might be wired for DBW wire already. If that's the case, then I will convert to DBW.

I seriously doubt that's the case, a ton of electronic changes were made in 2000. I can see the lack of a CAN bus as the main problem, that is assuming the ECU depends on it. Also things like cruise control could be tricky to get working.

That being said, if I do go through with this swap I'm still going to do all this because the 40v engines are just so much better.

[JumboBlack1.8]

Its becoming more and more apparent that finishing this project in the next 2 weeks is QUITE unrealistic (turns out its going to take 4 weeks for the Milltek downpipes to get made IF we go through with the group buy).......I'm not abandoning the project....but the search for a daily beater begins! Any suggestions?? Looking for something very cheap

[Capt. Obvious]

The hardest part of this swap is going to be finding an S8 or S6 engine with low-ish miles.

A few weeks back, a local guy was parting out a 70k mile S8. The engine was still in the car and able to be started. He only wanted $1500 for it! Then he sold it out from under me when another guy came along and bought the whole car. [=(]

[JumboBlack1.8]

^^Wow, that sure is a heart breaker......I don't particularly mind the high miles on these motors, so that's been making my search easier. I've found a full motor w/ harness, ecu, accessories, etc in NH for $3k.....more than I wanted to spend, but it's local....so I'll at least get to SEE the motor before exchanging funds. Unfortunately, the shop is extremely busy, so I can't get the motor until the end of next week

[revolution337]

Definitely not impossible.

You just have two throttle bodies.

One doing the engine air management, the DBC TB.

And one sitting in the engine bay satisfying the ECU doing nothing, tucked away somewhere so it doesnt look like ass, and moving like the ECU tells it to.

The problem with that is the 32v tune would be different than the 40v tune, sure it would probably work but it's far from ideal.

EDIT: I misunderstood, for some reason I thought you were talking about a 32v ECU with a 40v motor. The problem I see with that method is you'll still get an error code for missing the throttle, which will likely put the ECU into limp mode. The electronics in these cars are complicated to the point where hack jobs and workarounds just aren't feasible because so much can go wrong.

[revolution337]

Did you get up getting that S8 engine jumbo, or are you still searching?

[JumboBlack1.8]

Not yet.....I was banking on getting one locally, but the guy's shop is swamped....so I haven't been able to swing up there to get it. At the moment, I'm focusing on getting a decent daily driver for my move down to CT. I think I'm going to take my time with this swap, get a low-ish mileage engine (at a reasonable price, if possible), and really get this thing installed without a hard deadline looming over my head.

It was unrealistic to think I could have gotten this done in 3 weeks.

On a positive note, I might be picking up an '05 1.8T 6spd w/ K04 and a bunch of other goods....only has a few needs.....slow, but it'll be a nice daily. Should be picking it up next week

Also, if anyone out there is interested in buying my stroker motor, PM me. I'm trying to sell it locally first tho

If it comes down to it, you may have to swap your subframe to the 2.8L or automatic one. In my car, since it was originally auto, my drivers side is the 2.8 one.

Your best bet is probably to get an S4 subframe. Not sure if they differ from a 2.8 subframe or not, so it might not matter.

[JumboBlack1.8]

Hmmm.....I'll continue to do some more research to see if there's a way around getting a new subframe.....I would rather not uninstall it.

[Capt. Obvious]

The subframe is probably fine, you'll want a tranny brace (or whatever it's called) from a V6 model though since they have two humps in them for the downpipes to go through.

[JumboBlack1.8]

Just did some more research......you're definitely right. I'll need either the drivetrain stabilizer brace, or an S4 or V6 subframe.......I THINK i may go the subframe route......Just ONE more thing I've gotta buy and install....damn

[revolution337]

It looks like when kaploww (I think that is his username) did the swap he used an AWE drivetrain stabilizer bar as the transmission mount. Not sure if he just completely eliminated the drivers side mount then or what.

[JumboBlack1.8]

I think that's what everyone who started out with a 1.8T has done.....I just don't feel comfortable eliminating the driver's side mount altogether. I'm looking into locating a V6 subframe and upper trans bracket locally

[revolution337]

I'd rather not have to modify/swap out my current subframe if at all possible. I wonder how stable the trans would be with just the stabilizer bar and the passenger side mount.

[JumboBlack1.8]

A subframe swap is easy. I'm not too worried about it anymore, especially now that the motor is out. Here's the Bentley DIY
http://www.dj-sures.com/GraphicFiles/Audi%20S4%20Documentation/audi%20B5%20Shop%20Manual/suspension%20Wheel%20And%20Brakes/suspension%20Wheel%20Steering/40-77%20Subframe%20remove%20&%20install.pdf

[revolution337]

Just so I'm clear, what exactly is the difference between the two subframes? If you use a 2.8 you can run both PS and DS trans mounts?

[JumboBlack1.8]

Exactly....The 1.8T subframe and trans mounts only leave room for a downpipe on the PS. The 2.8/s4 subframe will allow proper spacing for both downpipes. .....Hopefully everything will go together without a hitch

[revolution337]

I see. Another topic, I'm not exactly sure what flywheel I can use for this swap. Obviously I need something that will allow the trigger wheel to line up correctly with the sensor, as well has have the 8 bolt pattern. And whats the deal with the trans spacer? When is this necessary? I'm getting some mixed signals as to if this is needed or not.

edit: pilot bearing? I haven't figured out what to do there yet either. The more I dive into this project, the more I realize how much work this is going to require lol

[JumboBlack1.8]

Yea, it's certainly not nearly as easy as I was anticipating, but fortunately, I'm picking up a DD next week, so this project will be done at a more reasonable pace. As for the flywheel, I got a spec b5 S4 LWFW, because it was available at a great price. If it doesn't work, I'll get rid of it. But, from what I understand, the transmission spacer will aid in getting the trigger wheel to line up properly......There are definitely a few things that I need to iron out as well

[SeekB00st]

I see your running a AME tru boost controller.

[JumboBlack1.8]

I was......ya want it? $225 shipped

[walky_talky20]

Just to add some more info (or confusion) to the subframe issue, I'll add that (AFAIK) all B5 subframes are effectively the same, other than 1.8T *5-speed* subframes. So a 1.8T automatic, or V6 automatic, or V6 5-speed, or any B5 S4 subframe would work to fix your issue there. The only one that *won't* work (and requires that chunky mount) is the 1.8T 5-speed subframe, which happens to be the one you have.

[JumboBlack1.8]

Yea.....working on hunting down one that is V8 friendly....Thanks for the info

[beemercer]

once you get going if you want a hand with some work lemme know, I could stop by some weekend day and help out. I'm actually starting to consider doing this swap as well, my A6is too big to be fun but I love the 4.2/S8 cams/S8 IM/LWCP/LWFW stg4 clutch/longtube headers powerplant. I think in a gutted out B5 it could be some good fun.

[JumboBlack1.8]

Yea, I cannot WAIT to get this done.....it think the B5 chassis will be a great match for a S8 powerplant.....Once I get rolling on this, I may be shooting you a PM.....However, I have no timetable for when that might be....Will keep all of you posted

[kaploww]

as far as mounts go. I have eliminated both trans mounts, and will be running the DTS bar as transmission support. In addition to that, I installed a set of stern mounts. Between the near solid engine mounts, and the beefy stabilizer bar, I'm not even worried about it. those components are so strong. If the drivers side transmount still fits when all is said and done, I migh pop it back in, but as if now. Im not worried about it.

[ZimbutheMonkey]

Wow, good on 'ya for pulling the trigger. Best of luck, I'll be watching.

PS: subframe is easy to pull with the motor out. My guess is that you'll be changing out the uprights anyway, so it's not much more work at all.

[JumboBlack1.8]

The parts are starting to pour in!

For those that're interested, here's what I've got so far:

C5 A6 4.2 upper motor mount brackets (including oil cooler)
Stern C5 Motor Mounts
B5 S4 Transmission spacer
Dual 12" push radiator fans
SPAL 185-degree Harness
A6 4.2 Coolant Expansion tank
SPEC LWFW for B5 S4
034 SAI Blockoff plate
2.5" Milltek Downpipes (currently being made)
Other misc. items needed for the swap

NEED to buy:
S4 front subframe
S4 DS trans mount and upper bracket
Flywheel bolts
That's it so far.....still searching for a set of a6 4.2 lower motor mount brackets....I THOUGHT I'd located a set (through a supplier known here on AZ), but my payment was just refunded earlier today, and I've received no explanation for it.....SO, the hunt resumes......I'm buying a daily within the next few days, so I'm not in a huge rush to get this done. Hopefully my patience will pay off.

And, for my exhaust....I THINK I'm gonna try to mate the downpipes to a 2.5" B5 S4 true dual exhaust (I think techtonics and milltek make a 2.5" version....but they're rare).

And, lastly.....I'm regrettably STILL looking for an engine. I thought I had one locally, but I have yet to hear back from that shop, as they are constantly swamped with work, and they haven't gotten around to returning my phone calls or responding to my emails. SO, I'm moving on for now......

I'll post more updates as I continue to compile parts and install stuff


*EDIT*
Torn between which of these two cars to choose for my new daily:

Stock-ish IMOLA B5 S4 w/ alcantara, euro S4 rear, and oem RS4 front ** no extensive records, clean cosmetically, recent(ish) T-belt and turbo replacement

I'm leaning more towards the B6......but that Imola is hard to pass up.....I'm gonna be test driving both this weekend.

[Capt. Obvious]

Having had both a 1.8T B6 and an Imola B5, that's a tough decision.

The interior on the B6s are nicer and they're a bit larger/more luxurious feeling, and the 1.8T tends to be lower maintenance. However, 2.7Ts are just plain fun to drive, but they're a bit of a pain in the ass to work on.

Between those two specific cars there, I think I'd go with the B6.

[ColinAndrews]

I'll second the B6 with a 1.8T as a daily. The torque of the 2.7T is fun, but working on it sucks. The 1.8T with a K04 will still be plenty of fun on a daily basis and A LOT nicer to sit in.

[JumboBlack1.8]

Yea, I'm leaning more towards the B6 as well....I know the engines inside and out, so it'd be an easy fix, if need be.

I was just drawn to the B5 cuz it just looks so damn good....and I'd keep the bumpers for THIS b5.....But, I'd hate to have to work on the 2.7 when any problems pop up

[biketsai]

1.8t w/k04 and bigger interior seems like DD material to me.

[revolution337]

You have a link to the fans/harness that you're using? I'm still browsing around for electric fans and haven't decided on a brand yet.

[JumboBlack1.8]

I got some Champion Cooling 12" radiator fans on Ebay. I was originally looking for SPAL fans only, but I couldn't find a set of 12" fans at the time. I found some good reviews on them, and they have a pretty high flow rating. From what I've seen, they appear to be pretty good quality. Not flimsy or cheap at all. And comes with a full money-back guarantee!
http://www.ebay.com/itm/200660850548?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

As for the harness, I got this:
http://www.ebay.com/itm/200662473537?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

It's for one single fan. I'm thinking I may always run one fan (like a viscous fan) and use the other to kick in at higher temps (i.e. the stock auxilary fan).....still not sure

[JumboBlack1.8]

Btw, here's the mod list on the B6......think I'm def gonna go with this, if the test drive goes well

KO4 turbo giac x+ tune, tt 225 injectors
Forge 007 Diverter Valve
Custom FMIC
H-sport front and rear sway bars.
Koni sport shocks
H&R sport springs
B5 s4 engine mounts
Stern Solid trans mount.
Stainless Steel Brake Lines
B5 S4 Front Brakes, with Hawk Hps Pads
CM FX300 240mm Clutch Kit
034 motorsports high flow cat.
Auto Speed USA 2.5in stainless catback
JHM short shift kit
OEM RNS-E
raw carbon fiber interior trim
OEM V10 R8 oil and coolant caps.
OEM ECODE Xenon HID's
Diesel Geek Skid Plate

[revolution337]

Will you be able to fit 2 12" fans on the radiator? From my (rough, mind you) measurements I found that dual 12" fans won't fit, so I was planning on running dual 10"

[JumboBlack1.8]

Will let you know by the weekend. I thought I'd read somewhere that dual 12s would fit. If not, I'll go with 10s

I have one of these as my main cooling fan for my 1.8T. I deleted the clutch fan. I can't comment on life, but I've had no problems with it for almost 8k miles. (mostly highway 70mph+)

If you stagger the fans, you should be able to fit two 12".

[JumboBlack1.8]

How do you have that wired up?

[revolution337]

Little update on my end. Last night I got a chance to install my timing belt kit. New timing belt, water pump, thermostat, pulleys, tensions, etc. According to the guy I bought the engine from it was recently done, but I wanted to be on the safe side and replace it anyways. Some of the parts I removed were pretty rusted anyways, so I'm glad I did.

Next on the list is to do valve cover gaskets (probably going to clean up the valve covers and paint them too) and cam chain tensioner gaskets. Putting some new plugs in as well. Two of the coil harness connectors were damaged in transport so I need to fix those as well. Sorry I don't have many pictures of anything other than this one of my buddy slaving away on the engine lol.

http://i136.photobucket.com/albums/q167/revolution337/alex.jpg

[JumboBlack1.8]

Nice! Good progress! I'm really jeaouls....I wish I had my engine already, but I'm not gonna pick one up until I sell my current motor. I'm not in any rush any, since I'm picking up a daily tomorrow. Plus, it's damn COLD outside these days....

[biketsai]

B6?? or B5 S4

[revolution337]

I was looking around at fans and came across this.
http://www.ebay.com/itm/2-10-ELECTRIC-RADIATOR-FANS-w-RELAY-TEMP-SWITCH-/270817830347?pt=Vintage_Car_Truck_Parts_Accessorie s&vxp=mtr&hash=item3f0e0025cb#ht_1555wt_923

Good price for 2 fans and the switching harness. Only thing I'm concerned about is the quality. From the reviews I have read it seems decent.

[NeedingAnAudi]

I was thinking, couldn't you just use the stock fan wiring?

[Mad Cow]

I was thinking, couldn't you just use the stock fan wiring?

Problem is the aux fan turns on with AC and if the stock fan isn't cooling well enough. When I did my EFK I bought an adjustable termoswitch with a probe you stick into the rad and wired everything up myself. This way it's not pointlessly running whenever AC is on and it turns on at a safe temperature which I can adjust if need be. Wiring is really easy, I kept the fuse and relay wiring in the cabin so I only had to run 1 wire through the firewall.

[JumboBlack1.8]

B6?? or B5 S4

Went with the B6....picking it up tomorrow

[JumboBlack1.8]

Might need to go in a different direction with the daily....was supposed to pick up the car this morning, but I get a text from the seller saying his brother got in an accident last night, and he's at the hospital with fam.....I wanna give him the benefit of the doubt, but he's flaked on me a few times.........I'm moving to CT tomorrow afternoon, and desperately needed this car, wtf!

[revolution337]

tough break, sounded like a good car and a good DD. I'm sure you won't have a problem finding something else. Good luck with the move

[JumboBlack1.8]

Sure is....looking at a few B5's locally tomorrow....one B5 S4, and another B5 A4 v6

Nice to see this motor going for good use. You will have a very sexy setup un your car. V8 s4 motor, noggy interior, stock body. I remember Kyle telling me his plans for this car. It was going to be a nos queen but plans change. Look forwards to seeing this in person.

In my end, car is up and running. Street tune begins.

[revolution337]

^ good to hear you're up and running! I'm pretty excited about the outcome of this swap, plus it gives me something to do this winter.

[JumboBlack1.8]

Getting close to landing a deal for a complete S6 motor for a good price! 120k miles w/ everything

Shokan quoted me an unreasonably large amount of money for a bare longblock, so I've decided to explore other options

[revolution337]

Unfortunately the motor I got did not come with any accessories (alternator, power steering pump, a/c) so I still need to source those. The places I've been looking at have been expensive though.

[NeedingAnAudi]

My A6 engine is just about to come out. Unfortunately it looks like I will be rebuilding the trans and sending it on it's way. Money is tight [:(]

Did some more work today. Installed my 034 SAI block off plates, changed out the spark plugs, and sorted out some of the wiring issues. Lots of cut wires/connectors on my engine so I've been living in a sea of wiring diagrams for the past couple days trying to piece everything together. Still waiting on a new valve cover (right side has a big hole from loading the engine with a fork lift during freight) and once that comes in I'll clean them up, paint them, new valve cover gaskets as well as cam chain tensioner gaskets and cam plugs. Picture time!

Good to know [up]. All I knew was that they are completely different from my 1.8

[JumboBlack1.8]

Finally got myself a daily.....I went with the Moro Blue B6. What an awesome car this is! It's a little rough around the edges (previous owner was a smoker, and had a dog.....so it needed a SERIOUS interior detail), but it's amazing how much more refined the B6 is than the B5. And I am in LOVE with the 6 speed trans. Makes highway cruising much more tame. And the RNS-E is just terrific.....I'll definitely be swapping that over to the B5 when the time comes

No pics as of yet, but I'll try to get some when I head back home for Thanksgiving.

No progress on the project yet. Still searching for the engine, but the new job and move have been taking up the majority of my time....sucks...[facepalm]

Quick thread bump. There was a thread about this that I've seen before, but I'm not finding it now -

What are the main differences between the A6 4.2 and the S8 4.2? Rods, heads, intake manifold and cams are about it, right?

The latter 3 parts are easy to bolt on, but how important are the rods? What about the crankshaft, is that the same?

[JumboBlack1.8]

Check the first or second page. I believe beemercer explained all the differences

In my never ending quest to get the wiring for this worked out, I came across this connector. I've looked through several diagrams and I cannot figure out what its used for. In the engine bay, it looks like it could be somewhere near the drivers side firewall, in the area of the expansion tank. Any ideas as to what this is? If you can't tell from the picture, it has two wires; blue and a red/black.

is it long enough to reach to the front corner where all the fan and light wiring plugs in ? in front of the abs distribution block

thats the only place i recall seeing those type of plugs

[NeedingAnAudi]

I found one connector like that on my A6.

That connects to this

Then that wiring goes down to the alternator and starter.

The blue wires connect to the alternator

And the red wire connects to the starter

Hopefully this helps [wrench]

[hazard860]

just a re-cap we're talking about c5 s6 4.2 or a D2 s8 4.2??? and AFAIK these can not be supercharged??

[hazard860]

also i'm sure this has been asked before, but with a swap like this how does emissions work out?? don't need a super detailed explanation.

[revolution337]

You're the man alex! Thats exactly the info I needed, thanks! [up]

You're lucky you posted when you did, because I just did this:

Have you decided what your doing with it? Still just rebuilding the trans?

Well I ripped it apart and found some nasty broken shit. Replaced everything broken and refreshed everything else, now I just need to finish reinstalling the engine/trans. Best part was getting at that engine bay with a toothbrush. Cleaning all that shit was therapeutic. Good chance it will stay in the family though.

they definitely can be supercharged if one wanted to go that route. The only off the shelf kit is the PES G4 system though... which is garbage and not worth the money for the slim gains it'll make. That goes for any other M90 based 4.2 supercharger.

I think this is the next step for me.....I'd love to learn how to rebuild transmissions as my next major endeavor (well, once I get my CURRENT alien engine swap done).....I MAY buy a trash 6-speed trans and try rebuilding it myself.

After having a 6speed B6, I am having a hard time coping with that fact that my beloved B5 have one less gear than it should......we'll have to see what the future holds for her

[NeedingAnAudi]

Manual transmissions are cake. But I don't suggest tearing into an auto blind.

[o_o]...Whoa. Tiptronic guts *everywhere*.

[revolution337]

So I am currently in the process of trying to locate A/C lines for this swap. I managed to find a compressor/condenser fairly easily, but all the salvage yards I've called said they don't keep a/c lines, or fuel lines, or anything like that. If anyone knows anywhere else I can source these, please let me know. I'd hate to have to delete a/c with this swap.

[NeedingAnAudi]

I still think 2.8 lines would work, and that would let you keep the a4 condenser.

[discontained]

I PM'd Jumbo,

that 01.5 A4 Quattro Automatic subframe just sitting in my garage taking up space. :D

[revolution337]

Went and did some more work on the engine today. I noticed that the intake manifold flaps weren't able to freely move, even with some good force trying to turn them. Did a little research on it, turns out this is a pretty common problem on the 4.2. Looks like I'll be doing DIY this in the not-to-distant future.

And also going to be installing these bad boys as well. Both of the plastic vacuum actuated rods on my engine are in tact, but as a preventative maintenance measure I'll using these machined rods from gruven.

I figure I'll do as much work on the engine now while its out of the car, because its gonna be a PITA to work on once its mounted.

[walky_talky20]

I haven't driven one of these V8's, but I did drive a Jetta VR6 5MT which has a similar "active intake manifold" system. I test drove the thing and was very unimpressed, thinking the VR6 should have a lot more top end. It felt noticeably choked off above 4k rpms. Back at the shop I noticed all the vac lines were torn to shreds, with some just hanging loose. Redid that entire mess and it was like a different car after that. Those intake runner things really make a huge difference.

I did get the chance to see an S8 on a "Cliffs of Insanity" cruise a couple years back. The guy was talking about he had just repaired the intake system the day before, in preparation for the cruise. Both shafts were broken, so he rigged it up with *Paper Clips*, I kid you not. He said it worked great, and really gave him back some power.

[kaploww]

All my intake manifold stuff is pretty crusty too. I don't think I'm gonna bother with it though. As my wheels are already turning on a factory ECU controlled electronic ITB setup.

[walky_talky20]

^Say what now? Care to enlighten?

x2!

[revolution337]

Crank sensor, 02 sensors, alternator, p/s pump and expansion tank all have arrived. Valve cover gaskets installed, new plugs installed too. Shouldn't be too much longer until I get started tearing down the B5!

[JumboBlack1.8]

God damn, that is pretty. Great work, man.....I can't WAIT to get going on my swap.....I miss my B5 terribly....The B6 is nice and all, but it's just not cutting it for me....*sigh*

[NeedingAnAudi]

Hey revolution what fuel pump are you thinking of running? Honestly I'm cheap as hell, and if I can run the stock pump I'm going to.

I'm going to start off running just the stock pump and I'll see how it runs with that. If it become necessary to upgrade I'll probably add an inline pump, like a bosch 044

Let me guess, D drum?

[NeedingAnAudi]

Let me guess, D drum?

B actually

[ZimbutheMonkey]

Really? My understanding is that the D drum was always the weak point in these transmissions. How did you find the teardown/rebuild? I have a 5HP-19 with a cracked bell housing that came with a parts car. I've rebuilt the valve body on one of these transmissions, but never torn into the trans itself. If I ever have enough time burning a hole in my schedule I've been tempted to tear into it, just to see what they're like.

I've seen pics of them disassembled and I have the schematics for them. Just never taken one apart live and in the flesh. Nice thing about this one is that I've got nothing to loose by buggering it up.

Funny though, I've moved them around and knew they were heavy bastards, but looking at all the pieces on the table in your pic, I can really see why now.

[NeedingAnAudi]

I can't say for the 5hp19, but the 5hp24 weak point is definitely the B clutch. It took a while to tear it down, mostly because I don't have a shop full of ZF specialty tools. I've rebuilt auto transmissions before so it wasn't really a big deal.

Damn, shoulda done a DIY, between the one I did on the Valve Body rebuild and what you did, people with a tip might be able to pull off a complete rebuild.

But, I guess it's pretty much all the same. Keep everything sparkling clean and put it together the way you took it apart.

No! Then I can't rebuild them and make moneys lol

[ZimbutheMonkey]

Well, if it's any consolation, no sane person without a lot of time on their hands would try and rebuild one of these anyway. (a monkey however...[;)])

[revolution337]

Took apart the oil cooler today and replaced the commonly faulty coolant pipe (thanks for the info beemercer [up]) with the machined aluminum piece from Bufkin. Luckily, the plastic one wasn't broken so it was cake replacing it. I've read horror stories of the pipe crumbling into a million pieces trying to remove it.

Pic time!
