Okay guys I need help on which turbo to buy. Well I finally got a chance to start ripping apart the GVR-4 and do some major work that I've always wanted to do for like the past 2 years. Anyways I'm looking to get the car's power between 400-450whp, so what kind of turbo will help me get there? As of right now my plans to help hold that hp is 4bolt rear end, bigger front mount and piping, hopping to switch to the gm mas, 550ccs injectors, 250 pump, chip the ecm and get it socketed and capped, maybe cams and a built head, new clutch and flywheel, drive shaft by AMS, brakes, strut bars and sway bars, and other little things here and there. So from all that what kind of turbo you think will help me out?
