to make 400 horses, first thing is to rebuild the motor with a metal headgasket and be sure to machine the mating surfaces as smooth as possible. get a full 3 inch exhaust, lexus v8 afm and 550 cc injectors with a piggy back or standalone engine management for tuning, and turn up the boost. this is basic stuff for higher hp 7mgte's. the r154 can handle about 800hp and is only fitted on either a 1jzgte from japan or a 7mgte
