injector help

[Kracka]

550cc injectors will be perfect for your setup. Why will you be running so little boost on the street though? 10 psi is lower than stock. I'd run at least 15 if I were you, probably more (they'll be able to determine the exact amount when you're getting dyno-tuned).

Looks like you have a decent setup going for you, your next step should definitely be a FMIC kit though. I also don't see an intake kit listed, get a hard pipe with open element filter if you don't already have them.
