I just recently acquired a stock 1990 supra with a brand new 7M-GE motor, so fai there is an HKS Intake kit and an A'Pexi super air flow converter in it so far. I want to know what I need to upgrade in order to eventually bolt on a turbo, any input would be appreciated.

add a nice big CAT BACK exhaust and have a blast

forget the turbo

well if your looking to add a turbo where you going to be pushing some serious boost, you'll need to swap out the engine to a 7mgte, of couse the ecu, engine wiring harness. You'll also have to make sure your car has an lsd, and i'm not sure if there is a difference in the transmissions, supra girl would definately know, or one of the other more experienced turbo members on here.

nitrous might be the key as long as the comp and fuel system are upgraded

you dont need to swap the engine if you want to turbo it. you just wont be able to boost much. the 7m & 7mgte share the same bolt pattern for exhaust manifolds.
