Compressor measurements...
 

Hi guys!
picked up an airesearch t3 turbo (.48 hot/ .42 cold)
what i need to know, is there any way i can determine the trim of the compressor? (perhaps measuring the the inlet dia or something?!) i have a feeling it is a 45 trim, but i need some help. Also, how do i know if the turbine side is a stage 2?
thanx!
