I got a turbo today for super dirty cheap, but I'm unsure of its useability. This is the info that I know. It has a .70 a/r compressor housing with a 55mm inducer (roughly) and a 75mm exducer (roughly). <--maybe a 54 trim? Seems like a big housing though... Anyway, it has a 1.32 a/r exhaust. Not sure on the wheel size. I know that the turbine wheels are typically named after letters (p,q,etc.), but I don't know what each letter actually represents. What kind of turbine wheel would typically come with a 1.32 a/r housing and can I put a smaller housing on the same wheel? The turbo is in perfect shape other than the hot side housing is too pitted to seal the v band or manifold mating surface. I would love to get a different turbine housing that would work on a smaller motor than a diesel v8, but still work with the current turbine wheel. Any help is greatly appreciated
