Buy the Ash massives IC's with 2.5" piping. Go with the 740cc injectors hands down. Selin dual intake is a must, you should already have that if you really have 520bhp...MSP MANIFOLDS NOW, As far as turbos, there is a lot to choose from. The new GTX28's is what you should get, but if you have all the breather mods, the sport 700's/Z1 675(same thing) could put you in the 500whrp range
