turbo engine internals

[gig]

im at a cross path at the moment my goal is to achive a minimum of 500 rwbhp i know i need forged pistons but do you think i need to uprate the conrods and crank to forged items if not i will get everything balanced and the conrods shot peened i dont mind spending the money its just i dont want to waste money. every one in the uk that i have spoken seems to think the crank can only handle 400 rwbhp any pointers would be greatly received as im a total novice on totally over my head and loving every minute here are some recent pics

manifold still isnt finsished but not bad for a novice



to many track days im lucky i decided to remove the engine as the engine mount rubber was totally perished
