GOOGLE damnit, in 30 seconds I found this. S13 SR20DET: T-25, 60 trim 56mm BCI-1 compressor, 53.8mm 62 trim T-25 turbine, .64 A/R turbine housing. Journal bearings. S14 SR20DET: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing, 62 trim 53.8mm T-25 turbine. .64 A/R turbine housing. Ball bearing center section. S15 SR20DET: Same as S14, but with Inco turbine wheel (instead of GMR), cast divider wall between turbine discharge and wastegate. Pulsar GTi-R: T-28, 60 trim 60 mm BCI-1 compressor in standard T-3 housing. 79 trim 53.8mm Inco T-250 turbine wheel .86 A/R turbine housing. Journal bearings. GTi-R T-28 is a really good turbo. I think that it is better if you lose the T-3 compressor housing and get a housing off of the S14. This is a big improvement. With the T-04B compressor housing, the GTi-R turbo can support about 16 psi and 280+ wheel hp. Makes pretty good boost by 3500 RPM, too. ---
