i have a red 89 NA supra i want to turbo. i May be able to buy everything needed to turbo my car from parts of a 7M-gte motor. i was wondering if this is the best preformance AND price conservitive way. Also. has anyone done this conversion who could give an opionion and anyone with an estimate on how much hP and torque increase? around 7-10 psi until i build my motor up to handle power.
