Before I put my T2 motor and trans in my GXL I shoula took it apart and sent my rotors and upgraded them to 3mm seals and BP'ed my housings, I need to know what psi I will be puting up with stock turbo, and at what rpm, also will I be sufficating it? Would it be better to run a lower boost with stock ports? I just need to know if its going to peak fairly high boost like around 10lbs on my stock turbo at low rpms.

 

You down graded to 3mm seals and the BP will overflow the stock turbo and quite possibly sky rocket pre turbine EGT's.
