| Things like 60mm throttle bodies and larger intake pipes tend payoff a lot more at higher power outputs than your stated goal of 470hp. Try taking a look at: [ www.itsgotturbo.com ] Click their names for mod lists and dyno charts. I think a lot of what you do to the motor is going to be decided by what turbos you are going with. You can get 470rwhp from a pair of larger turbos on pump gas without much in the way of engine work. If you want to get a fairly small set of turbos and run a bunch of boost on them to make 470hp then the throttle bodies and extrude honed plenums may be more helpful.
