I have decided to put my s5 t2 motor in my 91 convertable so im going to be boosting my 85 gsl-se . So my question is what kind of power to expect , what kind of boost i can run on the stock 9/4 compression , 3mm sealed rotors ( Im going to rebuild it with 2 piece steal seals ) ? If anyone knows of a web sight or something , Please help thank you Brian
