Yes I know there's thousands of posts, but I can't find the info I'm looking for.


I have a 98' A4 Quattro 2.8L (AHA) and want to swap a 4.2L v8 into it.

Will this swap be like the 2.7 in terms of plug and play-ness?

I haven't found a post on my year with the swap and would like info. I plan on buying a donor car and having a shop do the swap.

Any info is greatly appreciated :)

The 2.7 is not plug and play for a 98, but thats besides the point.

Motorgeek has a thread reguarding this. Google "how to v8 swap your b5", should be in the first few results.

That motorgeek thread is pretty good start. And then read all the threads here a few times. That is how I got started... :D
