will nismo 555cc injectors handle this?

[D1 guy]

I am wanting to hit the 400hp mark with my s14, this is my setup:

s14 "notch back" sr20detGT2871R turbonismo 555cc injectors (enthalpy tuned ecu)nismo adj. fprwalbro 255 fpblitz fmicblitz downpipegreddy profec e01 boost controllerkoyo intercooler

Is 400hp possible? will the 555cc injectors be fine? Im wanting to know what to expect when I go to the dyno. Ive been told that 400 was possible, but I want to hear it from you guys b/c I trust you more.

the injectors will be fine.......i'm not so sure about 400 whp. your hp number will depend on alot of stuff......but if i were to take a guess, running about 18psi on your turbo i'd say around 325+-, but remember thats jsut a guess so you can't hold be to it if you top out at 547whp

555's are safe around 340whp max. im glad i got 800's because at 18psi i am currently at 69% duty cycle... and got up to 370whp

740's will do the job just as well.

I'd get 740s.
