View Full Version : B5 A4 V6 to V8 swap questions.

09-05-2014, 02:38 PM
I am curious about doing this swap since I can get a V6 model 5speed quattro with a blown engine for relatively cheap and there just so happens to be 4.2 at my local parts yard. I am wondering what all parts will be needed and what is the biggest pain in the process? Best to start with V6 or 1.8 model? Anything else to consider?

Best to start with a DBW V6 car. You also need to be specific about which V8 you get. Specifically, you would want a AWN. The immobilizer will have to be disabled, but at least the ECU is tunable to the manual transmission. Using one of the 32v V8's can be done, but requires more fabrication and you would want a car that is DBC.
