View Full Version : Question about Turbo Swapping...

09-17-2005, 09:00 PM
Well, my buddy TOTALLED his dad's A6 last night and I was wondering what kind of turbos are in a 2.7 biturbo A6? Could I buy them and swap them into my A4, or are they not compatible? Thanks in advance...

KO3's. Same as the S4's.

They are not compatable with a 1.8T.

Damn. What is the compatability issue?

i would guess fitment...im guessing that the bolts on the S4 turbos dont line up with the mani bolt holes on a 1.8t

even if they did fit, it wouldnt be an upgrade....

I'm talking about making my A4 biturbo...

wouldn't be worth it. swap the engine is a different story but still probally not worth it. that is the plan for my car in a few years

Sure if you drop the whole engine, turbos, whole driveline, ecu, full harness. This has been done before, but in the end it is cheaper to just sell your A4 and buy a used S4.

Exactly what I needed. Thanks, Mike.

even if you did want to do this you have to pull the motors on the 2.7's to get the turbo's off not a easy job but yes these turbos are not compatible anyways
