Necessary mods to handle 400hp??? anybody with 350-400hp and stock internals?

[deathBooster]

Need some advice from ppl who had 400whp. I am looking forward to move up to 350-400whp. What do I need?? just dial up my boost???

Currently i've got the gt2871 with 555cc nismo inj, greddy fmic, koyo rad, z32 maf, safc2 and i am running 14psi. I to max my 555cc injectors instead of moving a larger one. and buy a t3/t4 turbo.

I need to know if my internal parts are going to blow. if so I rather be safe and spend some extra money on the long. any comments?? i need hks step 1 cams?? what elsE?? do i need to rebuild??

anybody with 350hp and stock internals??

you will need a FPR of some type, FP gauge Bigger injectors, Standalone, and that should be about it. My friend is running around 350 crank right now with no problem and hes not even pushing his 740 tonami injectors.

I know many people ran with 350 whp for years.

If you start to reach 400whp and more, I would look into forged pistons at the very least.
