The Official B6 2.7T DIY/Swap Guide

[imallstressed]

Great info on the cooling fans. Anyone have any insight on running a return fuel line? Obviously, it will need a line back to the tank, but what needs to be done back there at the tank to accomidate this line. Thinking there would be a pressure regulator back there that may cause some issues and looks like my car has a few extra lines on the fuel filter than a car that was equipped with a return line.

I picked up a nylon fuel line kit from napa. Installed a 3.0 filter with no regulator in it, tied into the existing return from the filter. worked out great! Ran the nylon from front to back. tied into fuel rail

Anyone have success with 02x transmission?
I searched and searched, but didn't come up with anything final...just that it would fit with the spacer but nothing conclusive about the downpipes/transmount/jhm brace solution...

Anyone with the 2.7 and the 02x?
How is it holding up with your mods/ power?
What did you do for downpipe modding due to transmission mounts being in the way?
Which clutch did you use? b6 240mm?

What? Nothing needs to be done, tie it into the stock line... Your FPR is on the fuel rail.

1. ECU doesn't matter
2. Should be fine
3. Probably the same thing everyone else did
4. Clutch is mated to engine so you'd get a B5 S4 clutch

Looks easy enough to do. Thank you for the link showing this. Makes it look easier than I was thinking it would be.

Can anyone confirm weather or not the 3.0 and 1.8t have the same fans?

any suggestions brand of silicone hose？ except samco or 034... how about those ebay silicon hose for the engine?

[LINDW4LL]

The eBay hose kits are good for the most part. Exception is the TBB is always awful and needs to be trimmed a lot. There is one other piece that sometimes needs to be trimmed... F Hose I believe?

Get a Samco or 034 TBB

they did what he posted, we all had to run a return line for the 2.7 to run. Either oem, or steel or braided steel lines.

a little reading wouldn't kill you. As stated in the first post, here are your options:

1. Run the standard or aftermarket downpipes but get them welded to fit (I don't believe there are any downpipes that fit with stock B6 brace. Some said SSAC but others seemed to disagree)
2. Use B5 S4 mounts and run whatever downpipes you want.

just recently used did one with the sacc's, they fit but they rub the b6 brace, to get then not to rattle they need to be extended slightly, so no downpipes so far fit without mods, or the the b5 01e side mounts.

Thanks. And these mounts will not fit the 02X, correct? No side mounting holes?

[Steve Bassen]

Correct, 02X does not have side mounting holes. 01E and 0A3 are the only ones that would fit this setup.

[blitz2190]

correct, on my personal one I made my own, you could get an exhaust shop to modify them for you for fairly cheap.

Awesome. How is the 02x handling the power?

[blitz2190]

sorry I meant I made my own to clear the b6 brace. I have an 02 01e from the 3.0. but it would be the same for your 02x as the center brace is in the same location.

I found a guy selling a 2.7T from a 2000 A6. I need to make the decision by tomorrow basically and I can assist him in pulling the motor on Sunday. Says I can pull anything else that I want from the car while there. Also, I can start and drive the car before pulling the motor. Any words of wisdom before diving into this? I have a 2002 A4 Quattro, 3L, 6MT.

I plan on pulling the full motor w/ intercoolers, brackets, engine mounts, cats, wiring harness, ECU. Is there anything else I should go after? Is the 2000 A6 a good candidate?

The whole thing is a super deal. My only hesitation is that I am hoping the build (if I do build) or the swap doesn't end up costing me what an arm and a leg. I have been eyeing the RS4, but my darn car has been so reliable and good to be since 2008, and I have done nearly a 100k miles with it. So, being as what an A4 with 141k is worth, I am a bit hesitant to sell.

Any thoughts guys?

i supose the a6 is automatic so you will need a clutch from a b5 s4. you need to switch the ecu to manual from vag com if you dont have it that would maybe cost you 50-100$ . if you dont have acces of wiring diagram you will need to buy 2 bentley publicher . finaly for the exhaust you will need to extend them

for the rest you will be able to take part from a6.

ps: for your a/c don't forget to take compressor ( and braket) from your 3.0 and swap it to your 2.7 with hose

Thanks Kristof, great information

[blitz2190]

Going into a 02 3.0 you have the easiest swap, the only other thing you'll need is to have the stock dp modified or a set of aftermarket ones if you go bigger turbos (still need to be modified). And pipes made to adapt to the stock or aftermarket exhaust. Also the motor to power steering pump line, you'll need that from the a6.

[CRAIG1MACK]

Thanks blitz2190! I am actually looking at purchasing the entire car. It's in pretty good shape, so by parting it out, might be a funding stream for mods!

[blitz2190]

If it's cheaper I would get just the entire engine and harness the ps line and dp's, you don't need anything else from the car. Parting an a6 could take some time and scrap metal prices are a joke lately.

I have 02 a4 1.8 automatic, since it's my daily drive, just wondering can I buy the 03's 1.8 engine harness and modify it? I saw this one on ebay, seller is wolfauto... sent an email ask them wether this harness will fit my car, they said yes.... does this really work with me 2002 car?
I know 02 and 03 have some differences on the harness... Am I correct?

Not sure what you're asking. You want to make the harness while your car is operational? Yes you can use any B6 harness plugs/relays to make it.

On the downpipes I found some use APR downpipes dirt cheap that fit perfectly with no cutting, but finding those use is hard to do. I only paid 150 for them. Just here to share some car porn. I been riding for the pass week. Just got some minor stuff to iron out. Ended up buying new springs for my car, my original drop was too low in the front and finally got my power steering straight.

Can you link me to the specific downpipes you found please?

[RKLamb]

http://www.etektuning.com/atp-3-down...or-b5-s4-2-7t/
Well these are the ones I have here. But I was also able to fit ssac version 3 auto downpipes on mine but I have Frankenturbos. I believe the angle of the downpipe is slightly different on those. But the APR fit like stock with no cutting or welding for me. Still might be cheaper to fab some up. I got lucky finding those. Since getting my exhaust welded together over the weekend my car is quiet as a G37 and running no cats at stage 3. I was shocked.

[RKLamb]

Oh also since these don't connect to our system my midpipe section came from a 06 Mustang. Bolted directly to those apr then I had them welded. The stock bands weren't sealing enough, big time exhaust leak and loud.

[RKLamb]

You could get the APR midpipes but the Mustang version was way cheaper. I think paid like 118 for them.

Can anyone confirm weather or not the 3.0 and 1.8t have the same fans?

I used 1.8T electric fans in my 2.7 swap + b7 conversion

[AudiA4_20T]

1.8T and 3.0 fans are different.

[Poopcorn]

Not sure what you're asking. You want to make the harness while your car is operational? Yes you can use any B6 harness plugs/relays to make it.

Yes, wanna make the harness prior... Already got the 2.7

[AudiA4_20T]

Sure

[stringerb3ll]

1.8T and 3.0 fans are different.

I'm saying 1.8T fans work fine so if someones confirming 3.0 ones work we are all winning then. (surprisingly the 1.8t fans bolted to the b7 a4 core suppot)

You know you could get better intake Temps if you modify a 3.0 airbox for that intake pipe. With a high flow filter they work great.

[stringerb3ll]

it is properly scaled it works fine, the car has rs4 intercoolers and PWM controlled water meth my IAT;s are great, also I'm doing a single turbo 5858 very soon why i went with the pipe in first place)

who ever needs cruize control boxes i have some 16bit MCUs that allow b6 cruise control stalk to work with the b5 s4 ecu $250

for down pipes i took a pool noodle (the flotation device with some brakeline wrapped in tape. this made the template and send to a mufflershop i had 2.75" downpipes half hour later for 75 dollers in 304ss, i have a CNC plasma for anyone needing turbo flanges (material cost + shipping)

[AudiA4_20T]

All fans work. He asked if 1.8T fans were = 3.0 fans, which is not true

[stringerb3ll]

thats odd.. I believe dorman only has one part number for all b6/b7 fans, my 1.8t fans went right into the 3.2 tfsi b7 core support the differences must be minimal

I guess I could be wrong. I thought that they were fairly different though.

[stringerb3ll]

i have some 3.2 fans as well i actually ended up putting the 1.8t ones on thinking it was the 3.2l ones i got from weaker. for a fan module i noticed the bottom coolant switch has 2 temps grounded two of the wires used the other two to close ground to the relay, before i did a b6 ac compressor i used a relay that was triggered by pwm aswell that also closed the curciit the the secondary fan relay
