I got a hold of an airsearch garrett t3 turbo. not sure which car it's off of but anyways to my question. how do I go about changing the exhaust/compressor side to a t4? I know I need a new housing but how about the wheel? let me know guys. I'm still pretty new to the turbo game. thanks in advance. Another question, is it even worth changing or should I just invest in another larger turbo? this is going onto a H22a.

 

anybody?

 

tried a search and still nothing.
