got your pm tom. ok so when going with a gt28 series what size turbine housing should a look at for good quick spool. say in teh low 3000 rpm range. i know this will limit top end a bit. but i'm wanting my car to ahve a nice thick pwoerband. if it holds to say about 6700 rpm i'll be happy.
your car will never be like my car, after all you have common sense......
