400whp sr20 build??

[solow240]

Ok guys just wandering what all i would need to get my sr to put down around 400whp?? I will be starting to build the bottom end as soon as it gets back from the machine shop...The set-up on the car right now is

Redtop sr20detbrand new s15 turbo at 10psi650cc deatchworks injectorsmagen stainless manifold, turbo elbow, downpipe, test pipe, and apexi n1 catback all 3" greddy fmic, and rs bovz32 mafapexi afcwalbro fuel pumpgreddy profec b spec 2koyo radflexalite dual electic fans

The bottom end will have Eagle H beam rods, stock bore/compression with cp pistons, ACL Bearings, im still debating on what cams to run i do not want a rough idle, but would like the extra power, Also the car came with brand new greddy valve springs and a metal cometic head gasket, im not sure if i really want to use the cometic headgasket b/c i have heard a bunch of horror stories about them, Thanks in advance for any advice!

Just glancing at your setup, your going to need more than a S15 Turbo and more injector than those. Youll need at least a 2871R .64AR and more like a .86AR to hit 400WHP and a set of 740 injectors. You may want to consider a set of cams. The BC's are only like $250 or so.
