So i know im new to the forum but ive been lookin all over to see what diff. guys are doin to thier 1jz's to make power, ive been contemplating on a few diff. things but im tryin to figure out what setups make good power without wastin my money and buyin the wrong thing, id like to break into the 600hp range, and i was thinkin about twin gt28's, cams, and a power fc, but im not sure if the gt28's will get the job done, anyone have any suggestions or where i can research into this stuff more?
