Does anyone know what turbos from other cars would fit on an 1989 Audi 90? Also any have a turbo that would fit on my car?
thanks

Turbo's just don't fit. Turbo's are built. You can fit just about any turbo in the Audi 90, as long as you know what you are doing. You best bet is to swap out a motor from an Audi 5000 CS Turbo Quattro. It comes with a K26, or a K24- depending on what year you get the motor from.
