The Audi parts fiche(according to the local dealer) is calling for the same turbo for the 90 and 91 200 quattros. I know the 91 200q uses the K24 - does the 90 also use the same turbo? I thought that only the 3B engine used the k24 turbo and the 3B was only available in the 91 200q and the 92+ S4's (which use the K26) mike miller 91 200q
