If you want 400hp+, dont waste your money on the top end and make sure you get at least pistons/HG/headstuds in there. 400hp is about the limit of factory pistons and head gasket, and you'll be flirting with failure at that power point.

But yes, at 21psi, I made 420WHP on S3 cams, GTX2867 and supporting mods.

But do at least a set of 740cc injectors, and spend the extra money and do the external gate.
