    550cc at a push, maybe 630's... 550's should do it though..

    550cc but if you max them out you could fit a 4 bar FPR

    If REVO is your choice of generic stage 3 then here's what they have tuned for from their spec list.

    630cc fo sho but if you have a 4bar FPR then that will flow about the same as 630's

    I got 680cc and my car was tuned for 1.4bar of boost with gt2871r. Dont know what the duty cycle % was but I think theres still capacity for a bit bigger air mass.

    But if your map is supposed to use with some specific injectors then of course you should use those!

    I would choose bigger injectors instead of higher fuel pressure which wears the parts (fuel pump) more. Dont understand why people uses some "tiny" injectors if the car is going to be mapped with custom software...

    Wellys 550's on 338bhp on hybrid were 90% IDC.... Imagine what a GT30 can flow more :eak:

    What would Be the best injectors for about 400-450? Would a gt3071r be ok for this sort of power?

    S3Zek, calculated with values that badger5 gave (assuming that 338 bhp was at flywheel) then with 80% duty cycle you would need 730 cc for 400 hp and 820 cc for 450 hp. Those would be my recommondations if You want to have some spare on injectors size to get ~50hp more..
