    I would get larger ones to be on the safe side.
    43 lb inj will take you to about 500 rwhp.
    60 lb inj will take you to about 700 rwhp.

    What size turbo? How much psi? What size nitrous shot? These are all needed to know for giving you a good injector size.

    But from the basics of what I see, I would go with 60 lb injectors. That way you will never get close to maxing out your Duty Cycle. Too much fuel is better than running lean...
