The Official B6 2.7T DIY/Swap Guide

[AudiA4_20T]

So, I have a good chance to pickup a 2000 s4 tip, that was rear ended for pretty cheap, what would have to be done about putting an auto 2.7t into a 2003 b6 a4 5speed? I heard the cranks look different on the ends???

You need SAI block off plates, ECU recode, pilot bearing for the engine. Maybe a manual harness would help. Otherwise just follow page 1

Mine came off of an 01 A6 TIP, So I got the SAI block off plates, Pull the spacer off of the crank and my lightweight flywheel bolted right up to it, Got manual harness, ecu from a manual S4, I deleted the 075 and the 249, So from what I been reading I should have no issues since my ecu is from a S4 and not A6

i dont see why not... the engine compartment is zactly the same far as i can tell

[AudiA4_20T]

im still waiting on a 034 tbb and the correct t-bolt clamps. inside is a Gates blue racing timing belt and all new OEM wp, tstat, tensioners and seals. i have piggie pipes to go on with a true dual catless 2.5" exhaust. stage 2? ill need good DV's and a Hitachi MAF.

What exhaust? B6 S4 one?

Also, yes the 034 kit will fit

[quattroloco]

the exhaust is from the donor car, it is a custom job with 2.5" and strait from the cats (ill be deleting) to a 2in 2out magnaflow and then two tail sections that go to either side of the bumper. ill post a pic of it. very straight with only two bends each side, i may need to modify for the B6 but shouldnt be too bad. I may add a resinator where the cats were depending on the sound. i plan on adding flanges to the DP's for a "test pipe" to replace the main cats, that way when I goto the track I can swap the test pipe for a open dump off the DP's that exits behind the front tires. more flow and noise what do you think? ill see if EPL can do a mode for the open dump if it helps or do you think it wont matter as far as tune?

I was looking into the 3.0 core support here in Norway.
It seems like it's made of plastic; is that correct / a problem?

[quattroloco]

its more like a fiberglass material and its tough as hell... shouldnt be an issue.

[Charles.waite]

Holy balls I thought the 1.8t was bad with the spiderweb of vacuum lines and random shit. Jesus...

im pulling my motor moday and starting the swap but it includes a tip-6mt swap with it and im wondering about the gauge cluster coding... do i have to code the b6 cluster if im using a b5 ecu and if so do i have to do it before i do the swap?

Do it before the swap and before you pull the ecu and the tip box. If you pull the tip box you will get a not found error code and you can't recode anything with error codes.

[quattroloco]

thats what i thought i remembered something about having to do it before... will it be totally confused if i code it to manual and then drive it home or do i have to do it here and then not use the auto again... its the only part im worried about of the whole swap. did you recode your ecu or did you put a b5 ecu in?

[RKLamb]

One more piece then I start dropping my engine in as well. Still trying to find those AC lines and need to do something about that snub mount.

I just did the snub mount again, this time with a 3.0L carrier if it helps. Still needs to be cleaned up, but you get the idea.

[quattroloco]

i think the snub mount off my 3.0 will bolt to the 2.7 and stuff right into that sweet little hole in my 3.0 core support. what do you think?

[B6A4Dave]

maybe its just me but this thread didnt tell me a damn thing with regards to swapping...........

Lots of info here. If you want specifics, look at Clint's build thread and/or my build thread. There is info in AfourQ's thread as well.

[daihashi]

Probably because it's almost plug and play.. especially if you have a parts car.

ok, lets start. if everyone would grab thier 10 mm socket and ratchet we will begin with step one...

hate to thread jack... but i can get a 2005.5 b7 S4 with an engine issue. could i swap in the 2.7 from 2002 S4, the motor has 49k on and comes with turbos and all harnesses...for 3K. Is this worth a shot?

[IVRINGS]

If the price is just the engine, turboes, and harness then that is high. I got that for 1700 shipped.

[Audi 4 Life]

Can someone please clarify the exhaust setup? it says in OP's post that SSAC's downpipes work, has this been confirmed? And are there any other options other than those?
And also it says to use S4 stock exhaust, is this the B5 or B6 catback I'm confused because the motor we are swapping on the B5 S4 uses a single catback, and the B6 body uses dual, so which is it?

Dave, no offense, but if you didn't get anything from this thread maybe this swap isn't for you

Yes. Curious how much you can get the car for

[quattroloco]

is that "man on a buffalo?" lol.

you sir win a cookie!

[AudiA4_20T]

If you use the stock B6 mount- NO downpipes fit.

If you use the B5 mounts with the correct subframe- ALL downpipes fit

You would use a B6 catback, not a B5 one

Can you define what you mean by "correct subframe"?

[AudiA4_20T]

manual subframes don't have those half circle pieces welded in there that the 01E uses. Only the automatic ones have them I think

[daihashi]

So the auto subframe is the "correct" sub frame?

Coincidentally I'm an Auto.... and coincidentally I am also running B5 S4 motor mounts already. Unfortunately thought things have come up and getting a parts car for the swap will have to be put off until 2013 :(.

I think early B6 chassis came with them regardless.

My 2002 was manual from the factory and had them before we cut 'em off to fit my downpipe.


Most ideal trans mount is the B6 crossmember and was used in the 01E for the 2002-2003 B6 3.0L 6spd.

This is about transmission mounts not engine mounts

They were asking which ones were best to fit B5 downpipes with no modding. In that case, b5 ones are best.

[quattroloco]

I feel so proud to have earned his respect! Lol!

[Ori0n]

What kind of mileage do you guys get with the swap on a quattro car?

I shouldn't have to ask haha, but I'm very curious!

[AudiA4_20T]

20mpg with a bad MAF (running very rich)

[quattroloco]

I just drove my car for the last time with a 3.0... the swap begins...

[RKLamb]

Man I wished I had a 3.0 I finally got all my parts except the AC line. So tomorrow Im starting the process of putting it in.

[quattroloco]

I started today! first one to fire up is owed one frosty beer.
