My old setup was a drag turbo on a stock block gsr. My new setup is an 84mm darton sleeved with crower rods and 9.1 weisco pistons. Unfortunetly I spent all my funds on the block and can't upgrade my turbo at this time. Just wondering if I can get 400hp out of this turbo? I believe it is a 57 trim with the b housing. Just wondering what is the max hp of this turbo? thanks
