4.2 swap into 2001 A4

[The Russian]

I know there is already another member doing this swap, but this one is a bit different due to different model V8. BTW this is not a competition of any sort i hope we can both help each-other out with this.

after months and months of research I took the first step today.

I have a 2000 A6 4.2L engine with 62k miles. It is the drive by wire engine so it will be virtually a direct plug and play with my 2001 drive by wire chassis because all of the plugs are the same. I have the ECU and the entire wiring harness that came with the complete motor assembly...

Did the first test fit today to see if it is possible to mount the V8 onto my 5spd trans. IT IS! this means that i am not going to need to modify any of my driveline. Plus for the purpose that I need the 5 speed gearing will me much more usable with this power range, not to mention the 5 speed is a bit more reliable that the 6spd.

To make it work we used an S4 flywheel spacer so that the crank position sensor lined up with the RS4 flywheel. With that all in place the 5 speed clears the clutch assembly with no interference. I do still have to modify the spacer for a starter bolt hole.

RS4 Stage 3 performance clutch kit that makes everything work.

[Nebone]

Very nice. You seem to finish projects quick so this should be no exception [up]

[The Russian]

yeha hopefully the extra $2000 i spent on a drive by wire engine rather than the older drive by cable will make this more manageable. Going to get all the parts ordered this week and the plan is to switch the two motors out next monday. I'll put up pics as the come.

[projectb7]

Subscribing... This sounds like a cool swap and can't wait for the results. GOOD LUCK!

[JEmm]

sounds awesome! how much power do you expect to have at the wheels?

[jrock]

Always diggin in deep arent you russian![:D] Cant wait to see a local v8 swapped a4. Pleasse tell me you have plans to turbo it tho... That would be pure sex!

[Siena]

Nice project!

Bear in mind, the 40V engine is larger than the 32V - both in terms of width as well as length.

Are you going to retain aircon?? Because, no room for the electric fan, not in its stock location at any rate.

Yeah I'm going to have to play around with fan ssetups, probably end up putting them infront of the radiator like you did... From what I've measured so far the width should be in the clear and length wise I might need to chop the first firewalls bit but should clear to the radiator, we will find all this out next Monday I guess :)

[revbjeff]

I wish it was Monday....

[biketsai]

Wow! Cool to see another V8 going in a B5.

[The Russian]

did some machining today, got a piece made up for the trans spacer that is needed to place a hole for the starter bolts. Machined it down so that its the exact thickness so that there is no strain on any of the other components. Tomorrow, I will get the piece welded on so i can drill the rest of the hole out and then put it on the engine block which will allow me to use the RS4 clutch and flywheel and use my 5spd and stock sensor positions...

Is Troy helping you with this?

[The Russian]

Is Troy helping you with this?

Troy was supposed to but he quit from 3zero3, so it is mostly me and scott, as part of their sponsorship they are letting me use the facilities and their knowledge lol

[Siena]

You're best off running a single-mass flywheel, that way you won't need the spacer.

The spacer is 11,2mm thick, that's more forward length you don't want in your already tight engine bay.

Not much room to move rearwards either, especially if you're running a stock 5-speed propshaft, which is longer than the 6-speed one.

[The Russian]

yeah, we'll see how it all works out, trying to do it the most cost effective way, and I already had an RS4 clutch kit... the plan is to redo the cooling system anyway so that there is some extra room. Spacer is complete.

You should make somewhat of a DIY, that would be amazing.

[McGovs2.7TB5]

Subscribed. Cant wait to see it person.

[Flash]

Sweet! Another one. Thanks for sharing with us! Seeing this kind of thing is very inspiring. It makes me want to follow suit after I finish my RX-7.

[josmo]

this is awsome

[Siena]

Nice work there!

Actually, the engine can be fitted to the tranny, without having to pull tranny from the car.

You just need to undo the 2 front subframe bolts, so the front crossmember drops low enough to allow the V8 rear oil pan projection clear it. Mine went in that way with ease.

Did you remove the oil pan webbing, and the thick lip at the rear? It's not needed on a manual tranny, and makes future removal and installation easier.

[AWD Mike]

I want to see vids of both V8 B5's .... in car.

I want to be able to see the powah!

Then, I will buy one.

[getslideways]

did you end up knocking the 2nd firewall at all or were you able so squeeze the motor in there while keeping it in tact?

i am really excited about these projects hopefully I can pull the trigger on doing this aswell. Props to both of you for paving the way!

yeah we tried to stab it with the trans in, but for some reason we were having trouble with the last 5mm, could not figure out what was interfering, until after wiggling it around out of the car it finally went in.

hmmm, how far can you grind the rear lip on the oil pan? because ther would be fantastic if i could make that go away, because it is way too close to the subframe otherwise, do you have a pic of how much you ground down?? don't want to go too far haha

there is actually plenty of room behind the motor, so the firewall does not need to be touched.

[Jc61990]

have u considered getting rid of the 1.8 trans and using a 2.8? since its got longer gears it would probly be a lot better for the v8.... ill take the 1.8 trans off your hands too lol :P

[belinko]

No need for the 2.8 trans IMHO[:d]

[The Russian]

i'm looking for more power down low because for rallying and the tracks i'd rather be able to pull out of a corner faster than have an extra few MPH for top speed. plus you never really find yourself going above 120, and all the torque out of the corners is just going to be a dream with the 1.8 trans i think.

[JaVa]

freaking awesome!!

[The Russian]

toque mount done, will hopefully get everything hooked up and fire her up next week...

good work!

[AEB A4]

Watching this. Great progress

[antoanS4]

Nice build,when do u thing this is gonna be done

[somebody5788]

Wow the front of that engine looks exactly like a 2.8 almost. Water pump, alternator, timing gears, tensioner, and idler pretty dang close setup.

Whats the hp output on this?

Is the engine stock? All this work i would want a built engine in there...

300hp.

It's commendable he's installing the engine in the first place.

Secondly, it's always best to run an engine as stock initially, when carrying out an alien installation.

That way, it's easy to pin point any running issues, and not need to worry if it's attributed to the install, or an engine build.

nailed it on the dot... Going to work on the radiator situation tomorrow, so we will see whats in store... will also try to address the ECU power situation...

[Militant-Grunt]

I at least would put some nice cams in there and tubular manifolds...

[Siena]

Fitting cams will require mapping the ignition to suit.

If the car then runs like a dog, how do you trouble-shoot? How do you decide if the cams / mapping are at fault, or something else you might have overlooked during the wiring of the new system? Or if you've blown an ignition driver?

Ideally, you want to run the engine in its OEM state, once you're satisfied it's all running in good shape, then you can consider tuning it.

Haha, YES.

[slopoke]

so if its only 300hp why not just do an s4 swap? Wouldnt that be alot easier?

Why dont i see more people do the s4 swap?

[kevin12]

so if its only 300hp why not just do an s4 swap? Wouldnt that be alot easier?

Because its no where near as cool or unique as a v8! [:D] People like doing things that no one else really has done.

And its not really that simple of a swap, most cases its cheaper to just sell and buy an S4 especially in these times. Their prices have really dropped.

exactly... plus anyone with not experience can go out and buy a B5 with a 2.7 biturbo engine... but how many 4.2 B5's have you seen? Siena's? and then apparently someone else in europe has done one?

[Siena]

Same treatment my front panel received.

Besides allowing the front to fit, without fouling the engine, it also allows timing belt replacement replacement without removing the front clip.

The radiator can also be replaced without removing the bumper. [up]

[NeedingAnAudi]

I was wondering if the 5-speed is able to handle the new hp and torque? Or is your trans beefed up already?

if you can do it in a month... kudos from me :) thats what my ETA was when i started... unless you buy parts from Siena, but then that should take a matter of a few days because he put a lot of time into R&D for all that. I'm glad him and I are able to motivate so many of you though...

Are you running air con in your car? That's one thing I don't have to worry about - a condenser in front of the rad will raise engine bay temps a fair bit.

Second thing - if you're not running air con, wouldn't it have been better to run the fan in front (grille side) of the rad?

haha A/C delete is the first thing i do on my cars... so no air-conditioner in this one either haha... one thing that is a bit more annoying about my drive by wire engine is that it has a more complex evap emissions system which i have to deal with in order to pass emissions in CO damn environmental hippies haha... Siena, what temperatures does your car run at?

[Siena]

Mine runs at 89 degrees.

[NeedingAnAudi]

What kind of parts list do you have with this project? So far I know of

Engine (Obviously)
Flywheel adapter/new flywheel
Different clutch - does the clutch have to be upgraded from say a 2.8 clutch?
Custom engine mounts
Custom radiator support
Some kind of ECU remapping? - I'm no good with software
And???

[Siena]

Flywheel - I supply custom single-mass items, designed to accept a B5 RS4 clutch, and mate to 01A / 012 tranny (5-speed) or 01E / 01X (6-speed.

Clutch - B5 RS4 clutch.

Engine mounts - I can supply a custom 3-piece set-up.

Engine management - supplied with map, enough to start and drive, but will need tuning.

Radiator support is modified stock item, with either S4 or V6 radiator.

You can still retain aircon.

[NeedingAnAudi]

You can still retain aircon.

Ok if I have all the parts, this swap actually shouldn't take too long, I can make the motor mounts but how much would that map cost? I'm just brainstorming for now because I found a 98 a4 5 speed with a bad v6 2.8 for really really cheap.

[Siena]

You're looking at £1,250 for management, wideband 02 sensor and wiring harness, with a running map and software.

I hope your base car's quattro!

Oh did I forget to say that? Of course its a quattro, I need awd for the winter. The engine is a complete engine from certified auto recycling, so I know they do a good job, it'll have a full harness. I was also thinking that if I found a 4.2 a6 ecu or an a8 ecu could that be made to work?

[Siena]

Yes, an OEM Audi ECU can be used.

solid... props man props
its goin to be a monster

[The Russian]

after living in wiring diagrams... it only took a matter of jumping power to two pins on the ECU... phone could not handle it...

[tj4891]

sounds badass!

[NeedingAnAudi]

What ECU did you go with?

[blmlozz]

4.2 weighs a little less than the apb correct? That would be a nice little something if it did.

[pipe7284]

damn, congrat!!!! sounds bad ass. but is that lifters i hear?

[4Rings3Liters]

Absolutely awesome man! [up] [up]

[The Russian]

What ECU did you go with?

Factory V8 4.2 ECU, going to get it running like this first and then start buildding maps for it so that i can run E85 on it... but thats just a goal for a while from now.

[Siena]

Yes, V8 weighs less than an S4 engine.

It may sound mechanical and tinny, but cellphone videos never give a "real world" sound. Mine sounds better in real life, than it does on video.

[The Russian]

yeah, it sounds like a dream in person... just finished modding and welding the front metal brace that used to be the inter cooler piping... so now all parts are just about done... still have to weld in 02 sensor bungs in the exhaust though...

[The*Fall*Guy]

Totally amazing.. Subscribed

[G Men 08]

holy shit man you are really moving on this eh? nice work, and i have 2 questions.. how does that motor work with a manual tranny, and how did you do the ac delete? that should free up power because of less strain on the motor right?

[UnkleGatsby]

mostly because I want to subscribe.

[biketsai]

Congrats man, I was scrolling through page 2 and I saw those pictures of the downpipes/exhaust and it got me REALLY excited!!!

[The Russian]

holy shit man you are really moving on this eh? nice work, and i have 2 questions.. how does that motor work with a manual tranny, and how did you do the ac delete? that should free up power because of less strain on the motor right?

As far as tranny... it bolts right up to the 5spd that i have... i had to use the Audi factory spacer plate that they used on the the 2.7TT blocks so that they could bolt up to manuals and Autos without changing the block itself... I built the motor mounts around the transmission, so that they entire driveline was sitting where it needed to be and then the motor was just in front of it, so all the driveline is line up and works perfectly...

the RS4 clutch and flywheel made it easy to switch from the auto flexplate... the auto tranny crank position sensor is 24deg offset, but so is the flexplate... so when i put the flywheel on with the manual trans the notches on the flywheel and the sensor on the tranny both shifted 24deg and still worked...

A/C Delte was just a matter of rerouting the serp belt... the AC pump used to be right by the yellow box for the belt and the routing the way the belt ran from the factory is way different, but with a few pulleys put in the right place and a custom length belt this setup works perfectly... and yeah it frees up a bit of power because thats one less thign for the engine to turn... and drops like 50lb's in weight...

[Eurotuned_A4]

v8 in a b5 would be the shit. Lets says someone gets the parts that siena provides....how long would this type of job take? If i do this im going to pay someone to install the engine as i want it as smooth as possible and i dont have a bunch of experience so i think that would be smarter. I would love to see peoples faces if my a4 made that v8 sound though.

The reason why Siena's and my builds are taking a while is because we have to go through the initial research and development where we bump into all the various speed bumps... he has a sightly different build than mine, but still very similar... i don't know if his parts would work for my setup because he used the previous gen V8... i think is more fun to make my own shit anyway...

I can't really give you an exact amount of time as you will still need to modify the cooling, mess with the electrical, and just deal with the general problems one might run into... but idealy, a week or so should do it if you had siena's parts and worked on it all day every day

yea i understand why it takes some time obviously. not knocking on your guys at all. Just was thinking in my head how long it would take someone if they knew what to expect and had the proper parts to begin with. Both of you guys stepping up helps with all that though [up]

no, it is a factory RS4 flywheel... the auto flexplate and transmission crank position sensor are both shifted 24deg over, so when i put the factory oem rs4 flywheel on with the 5speed everythign lined up... and i will get some pics of the exhaust manifold clearances on friday when i have time to go to the shop and do some more work... there is about an inch on each side between the manifold and frame rail... and it is just a straight piped exhaust with miltek high flow cats... i will eventually get some muflers on it... but only if i get too many noise violations lol :)

No more than an S4, as the V8 aluminum block is lighter than the S4 cast iron one.

a lot. lol. but worth every penny.

Those are true duals, haha only on driver side though, because the gas tank is on the passenger side right there and you don't want hot exhaust by that...
and the site is the club that I'm the president for at CU Boulder.

I wish you had bought it... if you did the car would be running right now and not in pieces cuz the 16 year old kid that bought it is an idiot... I keep pestering him to buy it back from him or just parts back because it hurts me to think about that car being pulled apart and unused... I miss it every day... lol


this is awesome just read it all now tryin to catch up, hows it handle with the extra weight up front?
Handles just like it did before, i haven't had time to romp on it quite yet, so won't really know until i take it to the track on Nov 7th.

Haha I'm only 19... But I wouldn't have painted it like it is now. It probably would have stayed the same color, put a cage in and then start engine stuff. I also would have taken care of it, it had a lot of nice parts on it iirc.

how are the handling characteristics compared to stock/hows the understeer?

honestly... unchanged... if anything i feel it gripping better... because with all the torque when i give it gas in a corner a lot of the weight shifts to the back and the front can turn easily... so all in all, it handles extremely well... now i just have to throw on some stoptechs and teins and it will be perfect.

You could have used a 2.8 clutch/flywheel assembly or an S8 clutch/flywheel and not need that spacer, it give you and extra 3/4 of an inch to play with up front. There's a swap on motorgeek using a 32V S8 engine.

the 32 valve engine is also shorter and not as wide as mine, Siena did that swap rather well... i used the 40 valve drive by wire one... turned out real nice...

stock motor... the whole point of the swap was to have the power of a built 4 cyl, but have it be OEM reliable...

Made a heat shield for the intake so that the exhaust manifolds don't heat soak my intake temps. turned out to be pretty cool engine covers too...

http://photos-c.ak.fbcdn.net/hphotos-ak-snc3/hs004.snc3/11156_792573703883_10233085_45969190_6734553_n.jpg

I wonder if they make those intake spacers for that one that they have for the 2.8 and 2.7t. Fenolic spacer or something like that. But for an n/a V8 it might help. If you by chance don't already know what they do they put a little space between the intake and the block to keep it from heat soaking the intake.

Could be a cheap way to get a few more ponies w/o any tuning. Especially at the track where heatsoak could actually become an issue for you.

Now I vote that you get a vented hood as well hehe. I don't always like how they look but I bet you can pull it off w/ 2 side vents. Hopefully it would land one right on the intake and you could put a nice little heatshield up to it.

[G Men 08]

jhmotorsport.com sells the intake spacer kit for our v8!! I put them on my car

[nynoah]

Did not see you cover this in depth but what did you do for the wiring of the motor. I know you said that you used the harness from the engine and the V8 ECU. But what else did you end up having to do?

So sick dood. I just Went through this whole thread

[The Russian]

Did not see you cover this in depth but what did you do for the wiring of the motor. I know you said that you used the harness from the engine and the V8 ECU. But what else did you end up having to do?

it was a pain in the ass to find out why the car wouldn't start when the harnesses were plugged in, but once that got figured out it was a matter of running Key-on power to two pins...

[nynoah]

did the tach and all other ancillaries work. Do you think it would have been possible to run AC or was it just not possible.

By the way, the guys at 3zero3 are great people. Scott and Trevor are some of the coolest people around. I think I saw your car there last time I was poking around there.

[The Russian]

yeah the tach and everything worked perfectly... you could run AC.. but its even more weight up front...

and yeah I used to work at 3ZERO3, so they let me use their lifts when they were open, Scott was also a great help with the build because he had an answer to every single question I had to ask him haha.

you had mentioned a small issue getting the car started, and it being resolved with the power to the two pins, but could you elaborate? The auto v8 ECU worked without issue?

[G Men 08]

where would i get a belt for my 4.2 v8 that would allow me to bypass my ac?

[Kyle H]

wrap a string around all of the pulleys, bypassing the AC pulley and measure the length... then you can go to your local auto parts store and tell them you need a belt X length and make sure it's ribbed/not ribber and the right width.

[Storx]

i was wandering if you ever got all the check engine lights worked out of it?? as i seen it on for maybe the oil sensor when you started it up

[iamOvic]

awesome.....

[x1n54n3x]

and one more thing, had you wanted to lengthen gears, is a tranny swap the only option? Can the gears in our(1.8) differentials be changed?

[Eurotuned_A4]

it would probably be cheaper to swap transmissions....

[x1n54n3x]

it would probably be cheaper to swap transmissions....

can you explain a little? I realize a swap from a 1.8 to a 2.8 tranny would be relatively cheap, but in terms of simplicity for the gears? How hard would it be to swap out to taller gears?

[Castor Troy]

can you explain a little? I realize a swap from a 1.8 to a 2.8 tranny would be relatively cheap, but in terms of simplicity for the gears? How hard would it be to swap out to taller gears?

everything required to swap the gears would have to be done to swap transmissions anyway; plus the extra $500-1000 in labor you'd pay somebody to rip the trans apart and put your new gears in.

it's not an option, unless you like pissing money away for no reason.

[x1n54n3x]

so to be clear, the gears are in the tranny, and not the diff? I'm relatively new to the awd mechanisms, the last time I had looked into swapping gears it was on a rwd Mustang. The case with that being, open up the diff, install new gears, done. Thanks for clearing up the misconception i had about the gears being in the diffs.

[The Russian]

i was wandering if you ever got all the check engine lights worked out of it?? as i seen it on for maybe the oil sensor when you started it up

yeah everything but the check engine light is gone... the damn computer still thinks that somebody stole the transmission and it cant communicate to it...

and for the serp belt, I can give you the Continental Belt part number that i use, but its kind of a modified pulley system so you would have to remeasure for yours.... and your routing has to be way different than the normal.

Forgive my ignorant question but what is even the point of a trans if the gears are in the diff?

Give 3ZERO3 Motorsports a call, Scott found me a killer deal through one of his guys for my engine, i'm sure they can find you a good dbc one... their number is (303)456-8383, Tell them that Val suggested you call them and they will take good care of you.

Forgive my ignorant question but what is even the point of a trans if the gears are in the diff?

I'm not sure what the audi is geared at, but my mustang with stock gears was like 2.93 or something like that. 80mph=~2500rpm in 5th gear. with lower gears (numerically higher) like 4.11's, 80mph in 5th gear would be turning significantly higher rpms. the only reason i bring this up is because if i were to use the 1.8 drivetrain with a v8 swap, i'd be turning WAY too high rpms for a daily driver, especially because i do a ton of highway driving. i wasnt fully familiar with how audi's were geared, apparently it in the tranny as well as the diffs. i spoke with an audi tech and he said don't even bother tearing into the diffs, just swap out the tranny too.
and if if i'm wrong about how i've perceived these cars to be geared, i'd appreciate someone chime in and correct me please.

[G Men 08]

^^with me coming from a mustang as well, I too ask myself this question sometimes. When guys that use the car for racing purposes are asking how to get better ETs for cheap I just think about the rear end gear ratio for the mustangs, like you stated instead of the 293 gear ratio you would put in a set of 373's or 410's and while this does not give you any more horsepower, it just makes your car accelerate faster. Why dont people do this with audis?

[The Russian]

yeah, quite the disadvantage... haha, for me i do mostly around town.. so its not bad, highway is like 3500rpm which is a bit high...

...BUT. for the track, which is what the car is ultimatly built for, I could not ask for better gearing. I have not been able to max out 5th gear on the tracks that i have driven, so its just about perfect.

When I get back to CO from visiting the fam, the car will go into surgery mode, to be completely stripped, and race prepped so there will be more updates soon... :)

Oh yeah TEIN SS Coilovers installed. Front struts are S4 spring rates and valving, and the rears are as designed for the A4 1.8t to help with the added weight up front.

Will be developing an EDFC kit for the car since they are not applicable on the standard setup.

We would have to install new gears in both the rear and front diff. In the end it's usually a better idea to just switch out the tranny to a 2.8's with fewer miles on it. There was a lot of talk about getting a shop in Cally to rebuild, strengthen, and or install the fifth gear from the TDI's transmission which would have been great but I'm not sure if the deal ever really went through since mike-ptzero was banned.

Maybe he's posted it on another audi forum. I don't go to another other forum for car's besides this one so I would be oblivious if he did.

[Storx]

i know of a guy who has good connections on the tdi side of the world who is turning MK4/5 tdi 5 speed trannys into semi-race 6 speed trans using the stock transmission case.. its the same transmission combo used in the 450+hp/900+tq tdi lupo in europe... i imagine he could do a good setup on the A4 trans...or one that is a torson based tranny..

i tried the vag, nothing seemed to work, if i really cared about it i would send my ECU out to someone like REVO to completely reprogram it, the only lights that are on are the CEL and the Airbag light cuz i disconnected them, so its not too bad. All the other lights in the video went away once i plugged all the sensors in.

+1, anyone want to chime in? Also, in terms of initial cost (DIY) I feel that a gear swap would be more feasible. The upfront cost of a 2.8 transmission would be more than higher gears right? Are there even higher gears for sale anywhere? Maybe I'm missing the complexity in our diffs, but I think it would be easier physically and financially than a transmission swap. Anyone have diagrams of our diffs, resources, etc.?
I do see the advantage of swapping out for a lower mileage 2.8 transmission though- which might be the road I'd have to take (if i end up going though with the swap in the first place)

[Kyle H]

Good gears normally cost ~$300+, so that's at least $600 initial cost, plus the cost to install them and set the mesh... The 2.8 just takes unbolting the transmission, linkage, and driveshaft and swapping the trannies as far as I know. and the front diff is all funky.

[Storx]

for that cost i rather just purchase an TDI Audi A4 tranny from europe or the UK>.. it looks like im heading to UK as my next duty station so i might do some sourcing for us.. and maybe help the forum out on putting together a conversion kit.. kinda deal..an all in 1 package for performance and highway MPG!!!

There's 2 differentials in our cars. The center differential is built into the transmission and the rear diff in the rear axle housing.

The Gear ratios:
2.8 manual w/quattro
3.500:1 - 1st
1.944:1 - 2nd
1.300:1 - 3rd
0.943:1 - 4th
0.789:1 - 5th
3.444:1 - Rev
3.889:1 - Final Drive

1.8t manual w/quattro
3.778:1 - 1st
2.176:1 - 2nd
1.429:1 - 3rd
1.029:1 - 4th
0.838:1 - 5th
3.444:1 - Rev
3.889:1 - Final Drive

Another site has the specs you may want - http://www.audiworld.com/model/

The final drive ratio is for the center and rear diff. So if you want to change the final drive, you'll need both. I don't know exactly how the center diff gets power to the front wheels since it's in the rear section of the transmission housing, so it may be even more complicated than swapping the differentials.

I can tell you that a center diff from Stasis is $550 and the rear diffs they used to sell were about $2500 (I think. They might have been $1500). I went on www.car-part.com and found a 2.8 quattro transmission 60 miles from me for $550 w/90k miles.

Bacon, I really appreciate what you've provided! I completely underestimated the complexity, I'll go with the used 2.8 tranny given how ridiculous a gear swap would be versus a transmission swap. Just what I was looking for, thanks.

Hey sorry i've been MIA lol, swamped with school work and race events lately...

I used the B6 S4 mounts for both sides... the driver side only needed slight modification, where as the passenger side needed to be expanded forward by about 1"... I tried the A6 mounts and they were just not as close as the B6 S4...

The front torque mount is completely custom and i'm sure there are many other ways to make it, but it is vital so that the engine doesn't just twist itself off the frame rails

As far as transmission mounts... my car was a 1.8TQ so it only had room for exhaust on the passenger side... So I had to get rid of the stock mounts to fit the exhaust from the much wider engine block...

Hope that helps, and let me know if you got more questions.

Scotty,

I've considered a 4.2 swap several times, but the main reasons I decided against it is the initial cost of the engine along with the cost to produce additional performance from it. I think it's a great idea for someone who only wants to do an engine swap that uses an Audi engine who also doesn't want to make much more power than the 4.2 produces stock. I'm sure there are other applications where a 4.2 powered B5 would make sense, but personally I know that while the boost in power would be very welcome at first I'd be left wanting more and with the 4.2 the cost to produce more power is quite a bit higher than with other engines.

This is mostly true, however when considering the VR6 swaps, the V8 will reign supreme with regards to costs... WHY? you ask

For the VR6 swap you will need:
Engine management system
Flywheel
Oil pan
Mounts

All of which are BIG money. Granted you can turbo a VR6 and get alot more power from it when compared to the V8, but we are now discussing 2 totally different things.

The V8 can be had in power levels to 450 hp (RS6), with the N/A engines up to 360hp. Initial cost is low (engine can be had for as little as $500.00), and they are mostly a bolt in, and if your starting with a V6 car, the flywheel and clutch can be used on the 40V engines (not the 32valvers though).

So if your looking for stock power in the 300-350 hp then yes a V8 will suite your needs. But you BlkBullitt you are correct if you want more then a VR6 or 2.7 is a better choice albeit much more expensive.

Thats how it makes no sense. About equal hp #'s from the 2 engines, but way more tq from the 2.7t with just a ecu tune. Not to mention the fact that swapping the 2.7t engine is a hell of a lot easier than doing all the custom work to fit a 4.2 in there.[:|]

Scotty,

Scotty, I agree completely and even if you wanted to swap over a stock VR6 (assuming that you would one day rebuild it and go with a single turbo) the swap still is costly (and you don't really gain anything initially). I think realistically a N/A 4.2l (that will be reliable and doesn't need additional work... just like you said you get what you pay for) is going to cost most people asily over $1,000 (I said most... I know there are some people out there who either know people or are lucky). Personally, if I was doing the swap I wouldn't risk buying a cheap Audi engine that could potentially fail quickly or have issues that could (and would) further complicate the swap. I my experience with Audi engines it's better to pay a bit more and not have to worry about the condition of the engine vs paying next to nothing and then end up with a headache and an even larger expense in order to fix or rebuild it (and sometimes that's not even possible). As for the C5 RS6 engine I'm sure it would be out for most due to the fact it is 1) fairly rare 2) expensive to obtain 3) parts for it are expensive 4) it's even more complicated.

I know what I would do if I currently had the budget to do a swap, however, I won't be doing anything anytime soon as I've got more important things right now (getting married in Sept of 2011, working on getting a new business up and running, and hoping to buy my first house in the next year or so).

Also, sending you a PM about clutches.
