well said... i knew most of what you said scott... i was more interested about interchanging the sizes of the Compressor and Impeller wheels, as you said, different results would be achieved if they were to be swaped with say another turbo. (i dont know if that's possible, however, i am pretty sure it is) I was reading about a WRX owner messing with the compressor wheel of a garrett gt30R turbo and i'm not too sure, but, i think he swapped it with a different turbo. (Maybe a t04) although i'm not exactly sure.
He didn't post any results so naturally, i had a few questions.
(sorry i couldn't get back to the thread sooner... been a little busy...)
