Hi I have a 2001 audi A6 2.7l (bio-turbo). I was wondering what i would have to do to my stock audi to upgrade it to k04's.
Where could i get K04 turbo ?
are the ones on bay any good? godspeed ?
thanks.

 

In general the cheap E-bay turbos will not last as they should. They also tend to have issue with boost creep, due to improperly sized wastegate ports.

If you are looking to upgrade to K04's, find yourself a reputable tuner, since you are in Van, I would look up CTS turbo or Kinetic MS.

As for what is required, you need the proper turbo inlet pipes. That is all that is required, but it is recommended that you upgrade the injectors, MAF housing and accordion pipe, ECU tune, fuel pump, downpipes, exhaust, intercoolers.

PM me if you have any questions, I ran my A6 as a stage 3 for several years.

 

Thanks a lot. What kind of ECU chip did u get for your car?

 

I use VAST Performance, they are located in Michigan, I have used GIAC in the past, and my S4 is chipped by APR

 

Thank-you very much for your help.
