A T72 is pretty big,really overkill for the power level you are looking for.
A nice 57 MM compressor will do fine & let you make more power later if you want..
A turbine A/R of .63 or (T3 turbo) smaller will work,smaller if you want to spool up quick.
It depends on if you use a T3 or T4 turbo as they flow different.
A T3 .63 turbine housing will flow less than a T4 .63 housing.
