Hello, I wanted to finish my audio for the nürburgring. I drive with my colleagues small race on the ring. We all drive an Audi 80 B4 2.0l with 90 Ps. Now I want to have more power than the others =). I bracuhe more Ps and a faster acceleration. Therefore I wanted to install another engine no matter which Audi blow thing it is fitting exactly to my B4. Tüv etc does not matter There are some things that have to stay: 4 cylinder petrol Sc Gearbox Turbo or doesn’t matter engine displacement doesn’t matter main thing 4 cylinders You might be able to install a turbo or a machine with a standard Trubo Do you know how to use it?
