Default what injector size

ive been reading up on what size of injectors. 300hp is what i want to be for now. i was thinking 880cc is enough or is it too much. ive used the formula and it came around 734cc. 880cc is bit more than i need but i think it would be okay. correct? i forgot to say the engine is a turbo gsr.

you should be able to get away with smaller injectors by adjusting fuel pressure. iirc 550 might be a little small but when HONDRULES! calculated for me they were in the ballpark.... look for some DSM's

I hope when you say fuel pressure you actually mean via a GOOD ECU tune and NOT via AFPR (adjustable fuel pressure regulator). go with bigger injector that what you THINK you need b/c you will most likely want more power out of it after you play with what you have. it is easier to down play your injectors that it is to go beyond what the flow rate is (saves you from having to buy bigger injectors later down the road!)
