Picked up my S464 from Alamo today. They did a great job on it and came in $100 less than they quoted me.
Specs were bang on to Noreaster's numbers.
Compressor wheel : 63.5 mm inducer, 91.4mm exducer.
Turbine wheel: 83.5mm inducer, 74mm exducer.
Compressor housing*.63 A/R, with 5.0" hose-type inlet, and v-band-type discharge.
Turbine housing: 1.10 A/R, with 'divided' volute, featuring T6 turbine inlet flange.
Turbine A/R was larger than I thought -1.10 not 0.90.
Not sure if this will affect spool with the S480 or not but at least I shouldn't need a wastegate.
