while the to4e series turbos (a 60trim that was recomended is the biggest of the t04e compressor wheels) have the potential to flow 425 crank hp, none of them will do it at 13-14 psi on a 6cyl. the 60trims' hp potential is somewhere under 500 but this is at nearly double your desired boost level.


my recomendation is throw out your boost level goal and just stick with your power level goal. Throw the 60 trim t04e turbo on there and you will have a great midrange power level car. It will work great on a 6 cyl motor.
