at what point (engine size, psi) does the sc63 become a better choice? what about the "large" (t04s) sc61? any clues as to when ill be seeing max boost on these three turbos (yes yes i know there's a million factors, but im thinking a rough rough estimate here).i'll be running an h22a

 

doesn't precision have all the specs on their website?

or you can just pm Rod Short
