first of all, thank you for the info. and the turbo was on the car when i traded my screwed up hatch for it. and i am looking to get a new turbo, (a smaller one), because it doesn't do much for me unless i am on the highway and hallin ass. so if i get a different turbo, would i have to get a whole new set up? manifold intercooler piping,etc..? and the motor isn't completely stock, it has been totally rebuilt with vitara low compression pistons, but with stock rods and crankshaft. oh yeah, i am only running 8 psi.
