So I recently purchased a 1988 Audi 80 Quattro rally car with most of the work done already. The next step is getting the engine turbocharged. I have the 10v NG engine in the car currently and I could turbo that or find a later AAN 20v turbo engine and do a swap. Audi ran both the 10v and 20v and one point or another so I'm ok with either. Think is, I either need all of the turbo pieces for the 10v or find a 20v for sale. If anyone has any advice or knows where to get the parts needed, I would very much appreciate it.
