since this info isnt easily obtained and it requires dismantling a turbo to get these numbers, thought I would share.
compressor
inducer 37.7
exducer 52
turbine
inducer 52
exducer 42.5
the most modern turbo I could find so far is a garret gt2554r with almost identical turbine specs, ball bearing and much larger waste gate, too bad it costs more then the car!
