The Official B6 2.7T DIY/Swap Guide

[PKmode]

Yeah, I guess my write-up was useless, I only used K03s...

That's not what I'm saying at all. Why get bent out of shape because I made a suggestion that will add tons of reliability and potential for those who are doing it? If the motor is out, that is the time to go with bigger snails, if one can muster the funds. If you have all the free time in the world and actually and enjoy busting your knuckles to do a job twice, by all means do what is best for you. Most people that have the funds to do it, would probably rather do it right from the get go so they're not dropping the motor more than once. If turbos are ~$2K and one is paying for labor rates, it would make more financial sense to spend two grand up front so they don't waste an additional $1K or whatever when the k03s fail.

[gottaBdope]

Gotta say, mad rep to AudiA4_20T for all the things I've read from him here on the forums, especially this thread...but I whole heartedly agree with PKmode. I planned on doing some work to the engine while it was out before I installed it, but I didn't know how funds would permit... I don't think many of us are doing this swap just to be able to say we did it or just because it's different (even though both of those points are factors). I believe this swap is perfect for those who want more than what the 1.8t can give them...at least comfortably. So unless your current 1.8t is failing you, may as well take the time to properly situate the 2.7t with things that would be hard to do when it's installed. I'm horrible for patience, but I think I can hold out.

That being said, I would have no problem pulling the same engine back out to do more work as long as I have the time to.

Yeah, except $2k is not nothing...? K03s can do 300awhp with a nice powerband.... Why do you need to do K04s? I did a TBB and engine mounts, that was enough for me and the car drives great...

[RKLamb]

I agree with all but this swap is the best thing to happen to me. I sure did not want to buy another 4.2 V8 and do that timing chain again. It would have been 4500 just for parts to do the entire system and once you add in labor 9k was the lowest figure I got. I agree with PKMode on doing all you can while its out. But when I do upgrade the turbos Im dropping the whole thing out the bottom next time so it wont be an issue to pull it again. This is probably the second easier car to work on that I have ever owned. 300Zx other than spark plugs it was always faster to pull the whole engine out versus trying to do certain things in the car. My old 3000GT and Corrado G60. I could not get a mechanic to touch them even at the dealership sometimes. lol.

I know that man. I never meant to imply that 2k is nothing and I don't think PK did either. This build is to each his own. I intend on owning this car for an extremely long time...to the point where there isn't much left for me to do to it...and the only two ways to achieve that are to have A LOT of money, or have a nice little flow for a looooong period of time, which is how I will do it. I see nothing wrong with doing the swap and calling it a day, but I also see the potential of having the engine already out of the car, and that is the approach I plan to take. Who knows...by the time I actually leave Hawaii and have a house with a garage, I might try and figure out a completely different engine to swap in!

[nefkntym]

I would say as a whole if you have the engine out of the car, regardless of mods, replace these first :

timing belt and pulleys
hydraulic tensioner
water pump
thermostat
cam and crank seals
Valve cover gaskets

I had a stage2 2000 S4 and it was a blast on the k03s with a GIAC flash, so basically what Clint said above.

Good to know, def on the list of things to do. No need to swap in a "new" used motor if you don't already perform the basic/major maintenence on it first. Same goes for any parts. And I completely believe that the k03s are fun, especially coming from a 1.8t.

On a separate note...I'm going to go study your build thread. 770?!?!?!?!?!

Insane

[DevilS4]

I'm one of the guys that has decided to do the swap on K03's first to work out the kinks and then do bigger turbo's and a built 3.0 later (or sooner probably). It's really not that hard to pull these engines out once you have done it once and the k03's are nice until you have the funds to go bigger. Swap can be done for nothing but your time and labor if you have a good running engine to part out. Stg3 will make it a much more expensive ordeal. Up to the owner which route they want to go. Right now I just want to get these last 5-6 wires hooked up and see if my B7 will run [up]

Thanks to everyone who is sharing info on this swap and making it possible. 6 months ago most people said it would cost you a million dollars and wasn't worth trying.

[gottaBdope]

^ Very good point, work out the kinks with the k03s. That's smart.

GLWbuild man. Few wires left, gotta be exciting!

Hah hah. Yeah. I'm sure you'll post here once you get it. Looking forward to it. What you doin with the old engine? Couldn't be in bad shape, huh?

The 2.0t ran great, it's up for sale if you are interested PM me an offer and we can work something out

[gottaBdope]

Nah, man. Sorry for the lead on. I was wondering because I'm trying to figure out what to do with my 1.8 when I swap it.

[DevilS4]

No problem, been too bust playing with the car to even list it. Just sell you engine, I don't know what a used 1.8t goes for anymore but my 2.0t will more than pay for my stock swap.

[gottaBdope]

I know that I probably will just sell it, but somewhere in the back of my mind is the fantasy of putting it in a tiny auto cross car or something, lol.

[quattroloco]

Originaly I wanted to go Stg 3 before I did the swap...

Im glad I didnt. When I decided to just put it in and get everything sorted there were a few people that said that is probley the best route. One of them was clint.
I am glad I listened to sound advice.

Even as easy as we all make this swap sound... Dont fool yourself and think everything will be sunshine and lollypops.
Hell, just taking the correct motor out and putting it back in can be a bitch. It only takes one fucked up bolt or nut to ruin your day.

But we are talking about a motor that never came in this platform... it is a custom setup and you will have to figure some stuff out as you go.

But for someone to say its not even worth doing without going stage 3 is rediculous.

Have some patience and make your car work correctly with no CELS or warninglights or issues.
adding stage 3 before the swap is sorted will only complicate matters if you have an issue your trying to track down and sort out.

It is NOT a b5 and your Stage 3 kit will need some tweeking. I was at AMD the other day and thier Fancy intercoolers will NOT fit. no worries, I am going to pay him to prototype a set for the B6 for this swap.
But thats not my point.

It is not always about power. There is driveability and dependability too. And if you tell me that a 300+hp 4 cylinder turbo engine is the same as a 2.7t I will literally laugh at you.
You push a frickin 1.8 to its limits and you dont know how long it will last, or if it will be ok tomorrow. You end up doin a preflight checklist before your willing to go to the store.
It has NO torque.

I did a healthy stage 2. stock turbos and stock fueling.
I made piggie pipes and did a true dual 2.5 inch exhaust. You cant even do that on a B5. best is about 3.5" single
I spent my money on upgraded intercooler hoses and clamps, a good clutch and all new gaskets and seals on the top end.
A hitachi MAF, 710n DV's and a GIAC stage 2 tune... nothing crazy
but it will smoke most B6's. I could have beat a R32 VR6 with a decent turbo at the drags had I drove my car like I was trying to break it.
My point is this engine is badass and is fast and you will enjoy it. stock or whatever.

Personally I got it because I wanted an engine I could MOD... now how fun would it be if you went full retard from the get go? Doesnt leave much in upgrades down the road (oh yeah?!? tial 605, 770 blah blah blah...) thats not what I mean.
I mean have some patience, enjoy the swap, build your car... because ultimately it is your car and your opinion is all that matters.

[DevilS4]

Totally agree with quattroloco. I want to drop a stage 3 in right away but it's just not a bright idea. Getting the engine in the bay is the easy part, it's the little stuff that get you and getting it all swapped to an oem level before you mod shit is the key. I had to pull the engine out again after it was all mated to the trans because I forgot a spacer, could have been much more of a headache if it wasn't noticed before I got further along. Spent 4-5 hours trying to get good fitment from my intercoolers, running fuel return lines, etc. I think I'm going to love the car with my tune, downpipes, exhaust, intercoolers, and then worry about more stuff later. At least the info is getting out there and we can all learn from each other to make the swap as oem and easy as possible.

[gottaBdope]

Well put guys. I hate to flip flop on opinions, but straight to stg 3 isn't the smartest thing to do. It's so easy to get wrapped up in the crave for more power, but I suppose it's best to pace yourself and fully adapt to the OEM before changing it up. You all said it right.

I'm not posting on this thread anymore until I'm ready to begin the swap. I'm a little out of my realm now. I will keep reading so I can learn more though. Thanks so far!

[AudiA4_20T]

The smart thing to do is C5 RS6 motor, oh and I happen to have one for sale!

[widgget]

i guess i'll phrase my question differently:

Are there any additional considerations that need to be taken into account when doing this conversion from an auto 2.7t A6 to a B6 A4 running 1.8t with a tiptronic, (keeping the trans in the A4)? basically will there be ECU/TCU issues once i install the 2.7t ECU?
the trans will be upgraded so handling the power is not a worry.

[SleeperAvant]

Why keep the 5 speed auto when you can use the 6 speed auto?

[quattroloco]

you want to use a B6 tcu with a B5 ecu... yeah I would guess there may be some problems... but I have no clue. Maybee a newer 2.7 from a allroad would work if you defeat the imobilizer.

[PKmode]

Please read my statement again with an nonobjective point of view. I made a suggestion saying it will save you in the long run to put in the K04s right away. Fact: K03s will fail in time when chipped (will last longer with a MBC set to 16psi, GIAC files or similar trying for 20psi will expedite the failures). Fact: The Tiptronic transmissions are built to only handle a certain amount of Tq. Any Tip will need to be built to handle stg3 Tq. You'd be better off selling your tip while it still works and putting in an 01E which can handle big power.

I said if only 300Hp were the goal a BT would achieve it but yes, the power bands will be different particularly, low end Tq. It would be a lot cheaper and more economical to just do a BT kit if one only has mild power number in mind. The 1.8T weighs ~130 lbs lighter so in the case of around ~300awhp, it might be more efficient. PS- I doubt you are making 300awhp on k03s. Close, sure but more like 260-280 at the wheels if you go and measure on a dyno.

I agree 100% on getting all the PM done before you put the engine in the car. No question at all. If you are doing this, you should do the FULL TB/WP job and all that entails, (eve if someone claims it was just done) as well as the VCGs, cam chain tensioners, cam seals. That should be a no brainer as it is all much easier to do with the engine out. If not, you'll have to put the car into the service position later (not that big f a deal to me). That is just the start of the 2.7Ts basic PM that need be done every 60-100K miles. There are also tons of other things with these motors that I would replace before stuffing it into another car. Make sure he crank seal and rear main seal aren't leaking for starters. Make sure the aux. water pump is not leaking (just help a friend put in a new clutch after the pump it leaked down onto those components). The list goes on. EGTs and O2s are extremely common as are CTS, spider hoses, (F-hose if a 00 motor) and so on.

I'd highly recommend paying attention to the S4 forums and particular engine/drivetrain problems we've dealt with over the years. Sure it's not in the same chassis but most of the maintenance related to engine health is the same.

In no way did I put down AudiA4_20T. I've been driving B5S4s since early 2004 and have gone through every stg from stock>stg1>2>2+>3>GTs. I've pulled these motors and transmissions before with the last one just three weeks ago. I made some suggestions for those who have the funds and want to do it right, the 1st time. Personally I like to keep the engine in when I can as i is silly to do more than once if avoidable. As mentioned, if someone was paying for labor, the turbos will almost pay for themselves as most shops want $1K+ for this job.

There is no reason you can't do all the PMs and resolve any known issues before putting it in to the car and go full stg3 if you have the means. For those that are timid over $2K, I would say you might want to stay away from these motors. It is often the case of the S4 guys putting several thousands a year into keeping their cars running in perfect health. Don't believe me? Hang out on the S4 specific forums for a while. Personally, I do a lot of PM so that hasn't been the case. I average maybe a grand per year overall but I DIY almost everything.

I know this will fall on mostly deaf ears as some of you think you are already experts on the subject but I warned you of some of the things you will probably encounter.

As positive reinforcement for those of you doing the swap. You can look forward to decent power from a stock long block assembly. Here is my dyno chart from last year at 24.5 psi.
http://farm7.staticflickr.com/6158/6135321580_541e8261a0_b.jpg
I've been running these power levels on a stock long block assembly for years with no issues. I love my 2.7T and am glad to see some of you doing this swap as I've always felt it was one of Audis best motors ever.

Kudos to AudiA4_20T for making the write up.

[widgget]

Why keep the 5 speed auto when you can use the 6 speed auto?

are you asking why i don't switch to a CVT? if so i'll take that as a joke, if not please explain since i was unaware that there was a 6 speed tiptronic (the B6 A4 is the only Audi i have any indepth experience with).


Fact: The Tiptronic transmissions are built to only handle a certain amount of Tq. Any Tip will need to be built to handle stg3 Tq. You'd be better off selling your tip while it still works and putting in an 01E which can handle big power.

I understand the TIP can only handle so much tq, but it will be built with at the very least a TQ converter and valve-body at 517 if not more. the 01E is a manual, i have a host of reasons which i have already listed as to why i do not want to do a auto to manual swap on this car. again, i am not concerned about handling the power, all i want to know for right now is if i will run into any issues with the ECU/TCU combo (or what the recommended combination would be).

[quattroloco]

Dont take me wrong PKmode. All I was saying is there is a very good reason to put this motor in a B6 EVEN in stock form.

The power is night and day difference from my 3.0.
also... I read every thread there is on the B5S4 forum as I was prepping my 2.7 for the swap.

Its like 4-6 hours to pull one of these engines for me so I dont mind putting it in and taking it out. Most all guys on here doing/did the swap do all the labor themselves.
That being said I dont see it as rediculous to swap one in in stockish form (with PM already done)
enjoy it... blow the ko3's up and then upgrade.
Im happy to know the swap is happy and working flawlessly and can start my stage 3 parts/fund and by the time my k03s go ill be ready.
By the way... personally I think that the k03 is a pretty robust turbo and have proven to be pretty tough little guys when treated propperly and kept within the limits they were designed for.
Im running a 18-20psi spike with a fast taper so they dont get too hot so we will see how they last. Also everything was from a 150k mile A6 parts car... with 195psi on all cylinders with a cold compression test. dry cylinders.
Propperly maintained and cared for is the key.

[PKmode]

My original B5S4 just sold last week from the guy I sold it to. It still is on stock K03s but I used a 16psi file from APR just for that reason. Most guys push them harder and then you get a visit from the turbo lady. I was the first of my friends to get into B5S4s and several of them followed suit after seeing what a well-built machines they were. All of them went with tunes and all had the K03s fail, some within weeks.

Proper maintenance (especially preventative) is paramount as you say. I can't stress this enough. Trust me, I practice what I preach. Here is a shot of my bay fo reference.
http://farm8.staticflickr.com/7280/7711423868_e841be4f74_b.jpg
It didn't get this way on accident. There are immense amounts of time and money into making sure everything is as it should be.


Don't get me wrong, I'm not here to poo-poo on anyone's plate, I just want to give some forewarning to some who don't know what they are getting into. There are very few people that will swap that motor and not want to take advantage of it. In that respect, I stand by my statements.

Happy motoring, Gents!

[nefkntym]

That is real nice. ^^^^

I am definitely not one of those people that didn't take advantage of a motor swap. Having said that, I think I managed expectations very well. Especially since I swapped out a 6765'd 24V VR6 for my current lump. I guess it is all relative to the eyes of the beholder. For me the whole 2.7 swap, all the preliminary preventative maintenance and going straight to GTs (770s) had less difficulty than making the engine mounts just to bolt in the VR6. Then there was everything else. For me, coming from that, a GT'd 2.7 swapped in was pragmatic.

However, I will be the first to admit that everyone's situation is different and there is no one size fits all here.

[widgget]

http://farm8.staticflickr.com/7280/7711423868_e841be4f74_b.jpg


you sir, have a work of art there. nice work.

i've popped 3 K0x turbos already, the reason i went with the GT was so that it wasn't being pushed to it's limits all day long. so i would go with somehting more then the K03s but only after i am certain that the swap was complete and solid on a stock 2.7t. stripping the front end down over a weekend isn't a major deal really if your not in a rush.

[SleeperAvant]

are you asking why i don't switch to a CVT? if so i'll take that as a joke, if not please explain since i was unaware that there was a 6 speed tiptronic (the B6 A4 is the only Audi i have any indepth experience with).


Um……the 6 speed tiptronic from the 2.7T is quattro, not CVT. Why re-use the lesser 5 speed quattro tiptronic transmission when you can swap in the 6 speed quattro tiptronic transmission from the 2.7T car (B5 S4 or C5 A6 / Allroad)?

[widgget]

didn't know that. thanks.

is this the case for both the S4 and the A6?

/off to go do some reading.

[SleeperAvant]

didn't know that. thanks.

is this the case for both the S4 and the A6?

/off to go do some reading.

yes.

[widgget]

Do you have any references?

According to everything i see the only tiptonic used in the 2.7t is the 5HP19. there is a 5HP24 used on the 4.2l but this just uses a larger bell housing to accommodate a larger TQ converter but still is only a 5 speed, where i am going to have my 5HP19 upgraded i am not concerned about power. looks like the 19 is not easily replaced with the 24 due to mating it with the engine.

there was mention of a 6 speed tiptronic in the 05 all road, but i am looking at 01 A6's for a parts car since there is a $10,000 difference between them and a 05 allroad. i'll porb just stay with the transmission i have, get it built, swap in a 2.7t, verify everything is solid, then look at turbo options.

[fitMINT]

so who in here started with a FWD 03 1.8t?

thinking of doing this myself, not sure how much longer the 1.8 will last. the more i spend taking care of it is more i could put into a newer better engine.

[widgget]

you will spend much more on the 2.7t no matter how you look at it, they cost more to run, maintain, & repair. they are harder to work on, something to keep in mind if you are doing the work yourself, and have heard that they are more prone to issues.
while the 2.7t is capable of putting out some good power, it's not necessarily a "better" engine, and in allot of cases would be older then your 1.8t.

i sure as hell am not trying to tell you that you should not do this, but these are just some things to keep in mind.

[quattroloco]

Hotrodding a car is a trade off... driveablity and reliability must be taken into account.

but I think hp to hp its a great platform vs. other audi engines... and lets not forget these came in the A6, S4 and allroad for many years so parts are becoming cheap and easy to find.

This is true, but it is most certainly a better motor. More crank bolts, more FW bolts, bigger clutch, better internals, etc

[DevilS4]

Just for anyone thinking of doing a B7, all the same as the b6 (must use the 3.2 carrier or make something work vs 3.0). Only additional hiccup I ran into was bypassing the FSI pump controller and I did it with a simple 12v relay to switched power. B72.7t is up and running :)

Does this look right, http://www.ebay.com/itm/Bell-Housing-Spacer-Plate-2-7T-3-0-V6-00-05-Audi-A4-S4-01E-103-551-C-/350469363721 ?

You don't need the 3.0 carrier, but it is nice to have

On the 5k rev issue Clint had. I also have an 03a with no speed sensor. No issue revving the car up. Haven't gone over 5k under load because clutch is new but I can do it in neutral no problem.

On the 5k rev issue Clint had. I also have an 03a with no speed sensor. No issue revving the car up. Haven't gone over 5k under load because clutch is new but I can do it in neutral no problem.

I was thinking about this last night, I am not sure why there would be an issue. If the ecu lost the speed sensor it would just get an implausible signal error.

[quattroloco]

It seems that the issue is from early S4 ecu's. the 01.5 ecu eliminated my 5k rev limit with no coding and gave me back a rpm gauge... when I was running the 2000 ecu / bosch i had the rev limit, traction/abs lights, and no RPM gauge.

I had to convert to Hitachi MAF to use it but planned onit anyways for tuning... also, the MAF off my 3.0 was the correct hitachi MAF... same part number. I even used the 3.0 pigtail and followed the B5 wire diagram from bosch - Hitachi using the PINS not the COLORS.

That could be the work around as well. I have a 2002 S4 T box ecu. I know for a while I had an implausible signal error for the speed sensor and I never had a 5k rev limit issue.

[DevilS4]

I have the abs/brake/trac control error right now. Haven't messed with it yet. Enjoying driving this thing right now and making sure there are no real issues.

I was thinking about this last night, I am not sure why there would be an issue. If the ecu lost the speed sensor it would just get an implausible signal error.

Apparently the way the 2.7T ECU is set up is that it needs the signal from the speed sensor or else as a safety measure it will cut the rev limiter. You can't just plug the sensor in either, it needs an actual signal

No this is false information. You have the speed sensor plugged into the trans. You are talking about two different issues:

1. Getting tach info to the tach. On 2003s this will happen automatically, but the ECU will still give you a code.
2. Making the ECU happy (requires either plugging in a working sensor to fool the ECU, OR having a 2002 car which acts the exact same as a B5)
3. Tach is an ENTIRELY different issue (see below, but I have a feeling it has to do with coding not the actual ECU)


That could be the work around as well. I have a 2002 S4 T box ecu. I know for a while I had an implausible signal error for the speed sensor and I never had a 5k rev limit issue.

I guess we are learning now, but I believe that coding the ECU one way or another enables different things within the ECU. For example, On both my 2000 ECU and my 2001.5 ECU, the tach worked by pulling the data through CAN-BUS. There was no wire from the ECU to the cluster. On the B5, however, there is.

I do NOT have any ABS lights or anything. I believe this 100% has to do with coding of the ECU, not ECU year

[DevilS4]

Any idea on what coding I need to change to make my abs stop screaming at me? I'm guessing that I need to somehow get the speed signal from the trans unless there is coding to make it pull signal from the wheel abs sensors?

Can you share with us your coding for:

ABS

I would be nice to compare that of a working setup to ours that don't.

[quattroloco]

I will... as soon as I get Vagcom... will still be another week.

[thaifoodninja]

Alright, time for me to chime in, I'd like for ya'll for you look my setup over and of course I have a couple questions. I have acquired my donor/parts car (a 2000 a6, 2.7t with an 01e and 120k miles on the odo, picked up with minor front end damage for $1400) and my b6 (a 2003 a4 with a dead 3.0 and ALSO an 01e and 80k miles), I think i may be on track for the easiest swap ever. I'm 1/3rd done stripping the parts car for parting out, after which I will be pulling the parts I need for the swap. I wish I could do this "right" but since I'm just trying to get my car back up and running ATM, I seriously on a budget here unfortunately. the only extra I could afford was the JHM timing belt kit which I'll be doing while the engine is out ($330). Onto my questions...

Transmission:
I'm pulling the 3.0 and its 01e, and leaving the attached 2.7t motor and tranny together hopefully. I shouldn't have rpm sensor problems this way. I shouldn't need the trans adapter then, right? It would save me the trouble and time of pulling the tranny and fitting the clutch back on. I was able to drive the a6 around the block and the tranny actually shifts smoother than my a4's 01e, so it seems win win. I'm still not sure if the axles from the a4 bolt up directly to the older 01e, or if I'll have to swap the axle hubs. Not a huge deal if I do have to swap the hubs. I am also wondering if I can save myself a lot of work by keeping the 2.7t's wiring harness in place when pulling it out.

Exhaust:
If I read the comments right, will I be able to keep the stock downpipes on f I use the a6 mounts? I have a thermal R&D dual exhaust now, which should hopefully line up. More on that when I have stuff in place. But am curious if anyone has gotten away with the stock downpipes and how.


At the expense of sounding like a total idiot: my big question, wiring:
I need some clarification on the harness work. Clint, I know you have a sweet deal for the harness going, but I am curious as to what needs to be changed wiring wise to make it work. I don't think I can afford the harness right now. Since I should be keeping the a6 tranny and again, fingers crossed, all the wiring hooked up from the motor and tranny together, how much work am I looking at to getting the rest hooked up to the rest of the car? I've worked with low voltage wiring (I was a shitty home security system apprentice for a while) and comfortable doing car stereo wiring. Not sure if the biggest problem is getting the CAN bus talking and a couple other wires, or if its still a good couple dozen more wires to go along with it.

ABS has NOTHING to do with speed sensor, at least on mine

Just did an 03A swap (b6/b7 S4 6 speed) and got no ABS issues either. Got the 5k rpm limit though and no speedometer......working on it...

[kosmo38]

Fixed my 5k rev limit by connecting t10/3 ws/bl wire to t10m10 br/ro G22 veh speed sensor goes to cluster then to ecm. So now it's going from sensor to ECM. ECM is happy.

ah makes sense now. Damn didn't realize that. I was wondering why there were two vehicle speed sensor wires, should have caught that

[kosmo38]

I had to do a double take too cause the cluster pin out labels those pins tach in and tach out. Must be be translation

So no more 5k problems. Man if you were closer I would buy you case of beer or something. You save me some extra cash trying to figure that out.

You are correct, No more 5k rev cut! I think it's worth a bottle of patron!! Hahaha. Glad I could help

[AudiA4_20T]

Your speedo issue is either the sensor or the wire going to T10/10. You need to hook that one up

[nefkntym]

no speedometer......working on it...

I was playing around with the coding and have inadvertently done this to myself a couple of times. It seems that the ABS has to be coded for 4 cylinder, the speed is then sent by ABS through CAN. When you code it as V6, I think it stops the speed output because the 01Es were on the V6s and they dedicated speed sensors. The other part was the cluster coding, I was messing with the coding and I lost the speedo and the econ meter both times. When I coded it back to what it was originally with the work shop code (WSC) and set the channel 60 adaptation back to 1127/1129 the speedometer came back to life.

The trans adapter you speak of is already there... The engine and trans are already propperly assembled...
Keep your A4 axles... remove the cover from the inboard CV and it becomes a B5 style. You can then use the existing donor trans output flanges. Use the B5 gasket to keep the grease in the CV since you removed the cover. Its just pressed on so it pops off easy.

use the motor mounts on the donor engine if you cant upgrade to STERN although youll want to right away...

your downpipes will fit if your using the donor trans side mounts... I recomend "pigging" your downpipes... its free power...

You should be able to make your exhaust work... its not gonna bolt right up but its just metal and it all can be cut/bent/welded.

You can leave the whole harness attached to the donor engine, really the only way to do it.

you will see the harness issues... theres plugs on the B5 engine next to the ECU youll need to adapt to the B6 plugs in the body... next to the ECU.
Its about 40 wires youll need to either use buttconnectors or solder and heatwrap (best). Its not too hard if you pay attention.
PM AudiA4_20T for the wiring harness or scematic... and dont worry, a child could read his diagrams... theyre really easy to use.

Good luck and start a thread so you can ask questions there as you go....

Thank, quattroloco. I'll probably start a thread to keep progress.

I thought about gutting the DPs, but AFAIK, I'd need a tune to avoid a CEL, right? I know its a major PITA to take the DPs off after everything is in place, but I'd much rather have everything settle first. Enjoying a winter with the mostly stock system, before I start having fun tuning it next spring (there will be some mods going in eventually).

wow, I've died and gone to heaven! I have always loved the b6 chassis as well as the 2.7 engine. I have a "stage II+" s4 right now. May have to put it on the barter table for a b6 a4!

[RKLamb]

Ok for those who have B6 S4s the SSAC pipes wont fit. They touch the crossmember and leave a gap at the top allowing only 3 nuts to bolt down pipe. So I decided to put flexpipes on mine and they worked perfectly. So I paid 150 for the exhaust set. 30 for 6 inch flexpipes and 75 to have them welded. I also had the midpipe cut allowing me to match them up with my stock S4 exhaust. Sweet. Here is a picture of my DPs. Now the SSAC pipes with the flex may work, but the old ones without go for way less especially on here.

Basically the same deal I did with mine. I just used the band clamps, didn't get around to welding them in yet. Works good and much cheaper than custom downpipes.

First off I want to say thanks for the great write up. I already feel like i'm ready to go pull my motor. I have a B6 S4 6MT, and right now what I have for the list is the 2.7 motor/harness/ecu, trans plate, fans with module/harness, P/S line, and probably going to run a FMIC. From the 3.0 I need mounts, radiator (and core support so no fab on the snub mount?), fuel return line and filter and the A/C comp and lines. Which still leaves me with questions about downpipes, is there anyway that I'll be able to run a set without having to fab anything up? Not that I don't want to, its that i don't have a welder or anything.

[dus]

i use 2.4 radiator 8E0121251G - it`s only 2 flanges, not 3 as 3.0 but worse than the fact that it is low 632х414х34mm vs 632х450х34mm

You can use a s4b5 downpipes if you change the subframe from quattro car with tiptronic auto gearbox. Plus s4b5 manual gearbox side brackets 8D0399107S, 8D0399108AN and mounts ( or 01e analog) Minus 8e subframe 8E0399263BH.

[quattroloco]

yeah if you use the side mounts on the trans pretty much all downpipes fit

I'm a bit ahead of you. I have an RS6 motor at my house! Let me know if you're serious I've mapped out everything already.

Yes you're pretty much on the money and I absolutely love the S4 as a starting platform. I actually never used the B5 module, just wired the stock 4.2 modules (since they are beast) to turn on with the car on. As said below, you'll have to mod everything if you use the stock B6 mount, although I like it better. I suggest getting some stock downpipes and cutting them so you can drive to the exhaust shop to get welded

Yup

[AudiA4_20T]

Just an FYI to everyone, I'll be moving soon so the harnesses are on hold. I can sell the plans but you need to give me a few days.

[quattroloco]

I also modded the 2.7 radiator because I didnt want to try to plug the extra port... fits like a charm.

Oh and welcome to the best coast Clint!

[kosmo38]

Keep 3.0 radiator guys it easy, that way u don't mess with securing the condenser. This is what I did. 2.7 upper& lower radiator hoses, 3.0 radiator with lower radiator outlet "keys" removed and 4do-133-335 to cap off extra port on 3.0 radiator. U want to use 2.7 lower hose due to bend in hose for t-stat housing, but in order to use 2.7 lower hose the"keys" on lower radiator outlet have to be removed from 3.0 radiator. Hoses are compatible but will be "clocked" incorrectly. Ie hose will not line up to t stat housing. Remove keys by using hack saw blade, hold blade with fingers you want to be precise. Simple 2 min fix. http://i1257.photobucket.com/albums/ii512/kosmo38/063F5210-4F5B-462A-B9EC-047500BB5359-1603-000004BF16998E90.jpg

schlap it in there man... the wiring is done last and should only take about four hours if you solder and heatwrap. less if you crimp on connecters.

I could just be dense, but Im still foggy on this.

From what car do we use the trans mount to allow for the b5s4 downpipes in our b6 chassis?

[ajsaudi]

Ah sweet. I figured the fans would be a little more involved than two wires. Haha

dude, just go to an exhaust shop and pay $100

[p8nt]

Fair enough, but just for the sake of conversation, is there a trans subframe that works for this? An OEM solution per say?

[RKLamb]

Those SSAC pipes with the flex may work. I had the ones without flex and could only get three bolts on them. I had a shop weld flex sections in them and they fit perfect right now. So I would try the SSAC with flex if you wanted to just buy something.

I understand there are other good solutions like you came up with. Someone eluded earlier that there was a factory cross member from a tiptronic (see post #355) that would work without modifying the downpipes. My question is about the car he sourced from.

Not a big deal really, just looking for some clarification.

I said the same thing in post #75, the subframe is from a tiptronic A4. Some of the manual A4s have the dog ear tabs on the subframe as well for mount the trans mounts. You should to see if you have them.

[AudiA4_20T]

You would need a factory tiptronic subframe with the "ears" for the mounts, the solid metal side mounts that bolt to the 01E transmission, and either OEM or aftermarket transmission mounts for a C5/B5 to make the downpipes fit

You're essentially making your car a B5. Those mounts are a bitch to remove, however, and most people add the DTS bar which is basically what the B6 comes with stock

[RKLamb]

Oh yeah if you live in a town where there is no competition for welding of steel get ready to get bend over with a broomstick. When I went back to pick up my DPs the guy wanted to charge me 250 and I was like, Man I can buy a set with the flex in them new for 300. So I asked him how much to make me a set of custom DPs and he said 300-500 dollars.

[nefkntym]

Stuff like that is why I bought my own mig and tig set up when I was doing my vr6 swap before the 2.7 swap. I know it is hard to justify the cost of buying your own gear to do a few hundred dollars worth of work, but you will surprised how often you will use it after you have it. The cost of constantly going back to the welder adds up quick. If you you have the ability to get your own setup, do it. For both the VR and V6TT swaps, I have not gone to the welder once and if you look through my build thread, that was a lot of welding from start to finish.

yep.. Even if you were to just buy a mig, if you shop around on craiglist you can find a good general use mig for a decent price. It will pay itself off the first time you make your own downpipe/exhaust.

[S4iowa]

Also, what has everyone been using for engine mounts ? B5 Units from what I've read.... FWIW, the B6 S4 motor mounts are 1/2" shorter than B5 units. This should help with down pipe clearance.

I am using B5 RS4 mounts. I know some people are regular and Stern S4 mounts.

[S4iowa]

We'll find out later how much 1/2 " helps or not. I ordered B6/7 034 Motorsport mounts.

Ive seen the stern motor mounts in conjunction with the 034 trans mounts kill all the slop... no DTS required.

is this wiring diagram correct ? i just picked up a long block 2.7tt for 250$ missing turbos and ecu , planing on swaping in my 02 b6 in the next few months

[quattroloco]

it depends on what year to what year auto manual ect ect

get both bentlys and match em up or find someone that makes a harness

[blmlozz]

Is there any reason why this wouldn't be possible with a B7 as well?

A4 requires fuel system changes, S4 is the same as B6

A4 requires fuel system changes, S4 is the same as B6

Thanks! I knew the platforms were very similar, but I had assumed (incorrectly) that there were very minor eletrical differences or parts revisions.

I suppose the B7 really is just a few extra nice body panels over a B6...

99% correct.
1% depends on what you're going to have to deal
Relay 271 is or is not in the wiring, there is a speed signal from cluster (ABS) or is there a speed sensor on the gearbox ...

What's the word on being able to buy the wiring maps? ;)

[RKLamb]

UPDATE: For those of you with B6 S4 when doing the AC you can use all the lines off of a B6 A4 3.0. You will need the compressor, compressor adapter, both ac lines and the high pressure line from the cannister to the firewall. You can still use the original low pressure hose from the firewall to condenser. Just spin the canister around to point the opposite directions.

Looks like I may be getting back into this.
Hopefully clint still has his RS6 motor.
The new plan is since I have a B6 3.0 a B6 1.8T and an Allroad laying around, swap allroad motor into 3.0, with 1.8t parts and put RS6 motor into allroad.

[victimdumper]

How much would this swap cost if I could do all the work myself?

completely varies, and depends on how you go about it.
some people have said it can get real expensive real fast,

...but some say they bought a good condition parts car and sold off everything they didnt need to come out pretty close to even

well, thats what i keep telling myself atleast [;)]

[T_S4]

That's what I'm hoping between the extra parts from my parts car and selling my 4.2 once it's out I can use that money to break even or even use for upgrades...can anyone tell me as far electronics go for the b6 s4 how difficult it is and what needs to be done? I really wanna get this project going.

I sold my 4.2 for 2K on Ebay. So with that and buying all the stuff that b6 S4 do not have and some upgrades but stock turbos, I am right at 4500. Could have been cheaper if I went all stock but I have a stage 5 clutch, tune ecu, had to fab up some down and mid pipes. Then a few mods here and there on the engine itself.

[S4iowa]

So... anyone figure out the wiring for the 3.0 ac compressor ? Be nice to know before I drop the motor in the car and it's harder to get to....

Anyone else get a wiring map from Clint? Trying to get him to PM me back takes weeks, I'm not sure if he's going to follow through or not.

Take the S4 wiring harness and get the 5 body plugs with about 6" of wire (flying lead) from that S4 or an A6 or and Allroad. Cut the A4 engine harness off about 6" from plugs (flying lead) get the S4 wiring diagram from here. (http://socals4.com/repair/) Get some more info about B6 harnesses from Clint's other thread here. (http://www.audizine.com/forum/showthread.php/425744-The-1-8T-Wiring-Harness-Explained) It would also be wise to get a B6 bentley CD as well. Grab some solder, a soldering iron and some heat shrink or electrical tape (fabric) and start putting the two together. It took me about an hour and to help put your mind at ease, about 85% of the wires from the B5 and B6 are the same color. It really isn't that hard.

If you can't get the body plugs from an S4, A6 or an Allroad...just cut the plugs off the S4 harness and cut the A4 harness back with as much wire as you need, then just solder them together like it was stated above.

You sir are a saint, rep points for you

Im running a b5 (which sounds like it should be even easier) but that covered it very well. I was only hoping the harness adapter would be done in time. Call me lazy but im willing to pay for the convenience lol. If it means a couple less hours of dicking around. That's why i bought the coil conversion for my wife's a4. Plus i like the clean professional appearance.

I have a full s4 donor car so body plugs are no problem. I'll be taking loads of pictures, maybe i can do a write up on the wiring.

I hear you. Im from the dsm world, made 300awhp on an $100 emulator and some open source software. I absolutely hate the "send it out" tuning options available here in the audi scene. A certain companies handling on a certain site about shutting down any and all talk of self tuning was disgusting, whether or not they sponsor the site. Hinders progression of the entire platform imo.

I am from the DSM world as well, this was my last foray before I went all Audi. My last Talon. (http://www.youtube.com/watch?v=N83d_1v6JIw)

That was done with DSMlink V3. As for the DSM style tuning, you can always use Maestro.

Nice talon [up].

Ever regret stepping away from the dsm? I've had four, all 1g's, just feels time for something different. I love link and the way they handle their business. Class act those guys are. Its always great talking with them at shootout too, they're knowledge just blows me away lol. As far as maestro, i started looking into that just before i gave up on the 1.8t. Its now the wifey's dd [:D]

I had 4 1Gs and that 2G was #5. I don't miss it at all. 15 years of DSMs was enough for me. Eurodyne makes Maestro for the S4 as well, I think you would probably be better off with a simple Jfonz tune though.

Haha, i know what you mean.

This part is particularly encouraging. So far im enjoying the aftermarket support i've found, full lines of proper parts. Not used to that.

Well luckily the donor had a APR "stage 1" reflash, so i'm sure i'll be happy with that until i get the proper supporting mods. The recipient car prep is nearly complete. Hopefully i can have some real progress in the next week or so here.

[S4iowa]

signal to the control valve of compressor will close control circuit relay, which will close the circuit coolant temperature sensor in the lower sleeve. diode and a capacitor 100 200mkf 50 volts should be used in parallel in the closing coil relay.

This sounds like the method for the single wire 2.7 clutch based compressor not the 2 wire B6 PWM based system.

Can you clarify?

[S4iowa]

Take the S4 wiring harness and get the 5 body plugs with about 6" of wire (flying lead) from that S4 or an A6 or and Allroad. Cut the A4 engine harness off about 6" from plugs (flying lead) get the S4 wiring diagram from here. (http://socals4.com/repair/) Get some more info about B6 harnesses from Clint's other thread here. (http://www.audizine.com/forum/showthread.php/425744-The-1-8T-Wiring-Harness-Explained) It would also be wise to get a B6 bentley CD as well. Grab some solder, a soldering iron and some heat shrink or electrical tape (fabric) and start putting the two together. It took me about an hour and to help put your mind at ease, about 85% of the wires from the B5 and B6 are the same color. It really isn't that hard.

If you can't get the body plugs from an S4, A6 or an Allroad...just cut the plugs off the S4 harness and cut the A4 harness back with as much wire as you need, then just solder them together like it was stated above.

Thanks, for this

This was the missing link... since I don't frequent here that much and it wasn't linked from any of the swap threads, I didn't see it.

Also, it will be a cold day in hell before Bentley gets my money again. Until they can update their software and provide an easy means of people who've paid for it, to access it..... XP is a dead OS yet they won't let you install on anything newer.

That needs to be added to the op. It would have saved a lot of questions.

Hello

Can you give me any information about swapping a 2.7t into a C4 A6? Its got the old 2.8 12v and the 4spd auto. Would the stock motor mounts work? Can the 4spd auto hook up too this engine and can it handle the extra 75hp and torque? Any other considerations?

Also any thoughts on a 4.2 swap into a C4? I know they did it in Europe with the S6 plus, but again I'd be mainly worried about transmission compatibility.

Thanks!

P.S. I've found a nearly complete 2004 allroad donor car that I could get any parts that I might need from.

I love it dude! Ok so you should be able to get the 01E in because the C4 URS4/URS6 came with it. The motor should also work based on the 12V V6 fitting. Wiring will be a bit harder, but might want to think about running VEMS. There are a bunch of 2.2T guys that run it and companies that can make a plug n' play harness for you

You will have to convert to DBW if you want to use the S4 ECU, and the dash might be a bit lit-up but otherwise it shouldn't be terrible.

Clint, first off thanks for all the info you've provided. If you're still making harnesses, I have an early 01 S4 2.7T that's ready to bolt up to an early 05 B6 A4 3.0 and am looking for any help you may be willing to offer. Your build thread and wiring pinouts have been a great help, but I still think your expertise making a harness will trump my hours and hours trying to figure out the last bits of wiring. Would appreciate a PM with any help.

i dont follow, are you saying this wire is unnecessary with proper ECU coding? because on a different version of your diagram, this was not listed, and if your diagram was given to DUS what was the intention of that wire?

[a4jason]

I'm way behind here, doesn't look like Audi offers the pins I need so I'm on plan B
Well, in that case any way you'd be willing to send me some diagrams you have? I've pinned out the 05 A4 connectors from the Bentley and am doing the same for the 01 2.7T, but I'm curious how you've handled some of the oddities that are coming up. Looks like 90% of the time is in 10% of the wiring from what I'm seeing so far

[nefkntym]

i have a T box ECU now is this ok? i read it is highly unchangeable with the M box ECU, i defiantly want my ESP to work, this is why i ask, the first ECU i bought was a A box "recoded to M box" basically the seller fucked me, i should have known when i didn't see a sticker, but now i have him offering to trade it for a "T box with sticker" or should i get my money ($150) ?

T box is fine, that is what mine is. EPL reflashed it to M box though when I sent to them for tuning.

It really doesn't matter as long your MAF is commensurate to your ecu. M Box, T box and possibly H box with expect the larger throttle body though.

Use the B5 or B6 01E trans, it make things simpler with the VR sensor and you get a strong transmission. There isn't much BS involved, it is just a trans.

[Hondasaregay]

So either or will bolt right up using stock tranny mount and drive shafts ? My car is a 2002 and correct me if im wrong but the 02s speed sensor is in the tranny. So will a b5 01E be plug and play kinda deal ?

[AudiA4_20T]

it does so you get a diff to match

B5 A4 5 speed - 3.89
B5 S4 6 speed - 4.11
B6 A4 5 speed - 3.89
B6 A4 6 speed - 4.11 (only some, rest are 3.89)
B6 S4 6 speed - 3.89

You have to change the diff with that trans.

You also have to reprogram to get your speedometer to read off the ABS wheel speed sensor since that trans does not have a speed sensor in it like your 2002 5spd.

Keep researching. Things will go smooth once you have a plan laid out with all the research behind it.

Since you guys are still struggling with the speedo issue/rev cut, I just wanted to add that I swapped my b5 01e in last weekend and resolved everything. There must not be a magnetic gear inside the b6 01a.

There should be a part number on it. Audi has part numbers on everything.

[stelvio]

Having read this thread and a few others on the 2.7tt swap, it makes me want to go out and do this so bad! lol There is something no one addressed: if you're swapping from a 1.8T, does the car ride worse or sit lower in the front due to the springs in the 1.8T? Should those not be changed? Obviously 1.8T springs are different from the 3.0...

[sandspeed]

I would change the front suspension to accomodate the V6 weight. There are definitely differences.

[Audiguy1234]

I doubt the weight is that significant to make it ride horrible. Worse case scenario is upgrade to coils if you haven't already or shift weight towards the rear like the battery is a good 50lbs.

[AudiA4_20T]

By the way, this wiring sucks and I don't know if I'll ever make these friggin harnesses. The Bentley manual isn't 100% and getting these wires and relays figured out is a pain. RKLamb may be the only one I ever make this thing for (lucky guy)!

Also, if you're gonna PM me, I ask that you

A. Have the wiring diagrams already
B. Have tried to read them and do it yourself.

Yes, I will answer some one-off questions when you get hung up. No, I will not hold your hand.

[nefkntym]

I don't think that is unreasonable. There are so many different versions of this and that. With the commensurate Bentley manuals, the wiring is a few hours worth of work at the most. That is faster than they could ever be produced and shipped, plus it will eliminate the hand holding. Remember how it was with Issam and the VR6 swap thread?

Also, if you're gonna PM me, I ask that you

A. Have the wiring diagrams already
B. Have tried to read them and do it yourself.

Yes, I will answer some one-off questions when you get hung up. No, I will not hold your hand.

The wiring is obviously a large factor for which some people [myself included] are perhaps hesitant to start the 2.7tt swap, it's obvious. But my question is what wiring issues are you having? Do you just have to match wire-to-wire from one platform to another? I actually enjoy this stuff and I could perhaps give you a hand. I don't have Bentley manual but I have ElsaWin wiring diagrams [although they might be very similar]. I guess I'm asking for clarification of what 'wiring' needs to be done.

I don't need help it's just time consuming. Yes it's as easy as matching wires to wires, but the B5 and B6 differ on certain things. Also, their ECUs are powered differently so that needs to be addressed. Can be done a few ways but I chose to match it almost exactly to the B5 to make things easier.

FWIW, there are ~47 wires on the B5 going to the chassis, and ~37 on the B6

OK subscribed! Count me in on this one. I already have the lock carrier off as I am fixing a 2005 A4 3.0 Cabriolet that was hit in the front. If I want to keep my auto trans I would keep my TCU and only swap out the ECU correct? I wont need the trans spacer; I can just reuse mine? Anyone have a lead on a complete 2.7t for sale? Not looking to build a powerhouse, already have built those. I just want to get rid of my 3.0l.

Yes I read that somewhere when I was reading this thread. How do you decide what to do with those extra 10 wires? After I'm done exams I'm going to get looking into this wiring business. I have someone wanting to sell me a 2.7tt from an S4 but it comes with a Standalone so I don't know if that will be easier/harder to figure out..

Damn, always wanted a cabby. Maybe one day.

They just kinda hang out

I need to do this.

Lol literally? I'm assuming they B6 platform doesn't use all the wires from the B5. I hope I'm not bugging you too much about this but I'd like to ask about other electrical compatibilities; is it just the harness wiring that's the issue or are relays/modules/other stuff that need to be adapted to the B5 ECU/engine?

[Vbzatty]

OK I found a motor. 110k miles though so I am going to freshen it up a bit before I do the swap. Once I do I will start a new thread. The wiring diagram doesn't look too bad but I am sure I will have questions as I go.

I will also use EPL for my tune; they did an incredible job on my 996TT tune.

1. Connect basic wires (coolant temp, oil pressure, etc etc)
2. Compare how they are powered (includes relays). ***Sidenote, this confuses the crap out of people, probably because the Bentley manual is 100% WRONG about the location of certain wires, verified with my own wiring harness***
3. Match B6 powering to B5 (can do this a few ways, my way is 99% like the B5)
4. ???
5. Profit

My suggestion is to saddle up and get the engine PDFs. Once you can read them you can make a shell of the 4 connectors on the B6 and 5 on the B5, and start filling out what each pin color is, size, and what it does. Then you can start comparing and you'll have the "aha" moment.

I love that moment. I've got two friends as Audi techs Im going to for help with diagrams and their general knowledge along with my modding abilities so hopefully mine will go smooth when that time comes.

Lol very well put. Thanks for that!

So I was looking for complete engine swaps and it got me thinking; what parts off my 1.8T work on the 2.7tt from the B5 S4? I'd rather not pay to have double the parts if possible especially if I've just bought them. So this is what I came up with so far [if this helps anyone]:

The Alternator P/N: 06B903016QX apparently fits:
A4........2001-05 A4/Avant
A4Q.....2001-05 A4/S4/Avant quattro
A6........2002-05 A6/Avant
A6Q.....2002-05 A6/S6/Avant quattro
AA4C....2003-06 A4/S4 Cabrio./qu.

The Starter P/N: 06B911023 apparently fits:
A4........1998-05 A4/Avant
A4Q......1998-05 A4/S4/Avant/quattro
A6........1998-05 A6/Avant
A6Q......2002-05 A6/S6/Avant quattro
AA4C....2003-06 A4/S4 Cabrio./qu.
ACA......1992-00 Cabriolet

Are there other components that could be kept?

[RKLamb]

There should be a part number on it. Audi has part numbers on everything.
