I figured this would be the forum to go to for this. I got this turbo attached to a $400 engine, and really dont know what it is. I dont have much experience with turbos (all theoretical, no practical), so i dont really know what to look for in terms of manufacturer, or where to go for the compressor maps.

This is just the compressor side, the center and turbine are stock S4.

 

T04B hybrid

Ok, next question... how could i tell what trim the wheel is? what shoudl i look for?

 

does the exhaust housing have an A/R #on it?

my exhaust A/R is (.81 a/r) there for it is a ptrim...

 

the exhaust is stock S4, just the compressor wheel and housing has been changed
