As far as the exhaust side goes, it's the smaller of the 2 exhaust wheel options. Here are all the specs I believe it is. I just wrote them asking for verification of it all.
Compressor Wheel: inducer-62mm / exducer-84.6mm / 54 trim
Exhaust Wheel: inducer-76.1mm / exducer-66.7mm / 77 trim
Exhaust Housing: .70 A/R, T3 inlet, V-Band outlet
Compressor map attached below. Also I'll post up a map of a .70 A/R GT35R for comparisons sake.
