So I have done some digging and apparently a NSG 370 isnt good with a 250 + hp V6. The crank and cam and heads and intake and TPS reset push it really far (throttle restricted to 70%) and can make in excess of 250 HP and 300 TQ. However the NSG is hardly capable of this kind of power. I would like to know what transmission can I use? 5 speed or 6 is fine I just want a decent overdrive and a manual.
