Hi! im new here but have ben on here for a very long time, love the community! heres my problem. My 300zx has the 60k maint done. I have 3 bad injectors, I need to purchase some but im not sure if i should get 370cc or bigger. my car is stock but i plan on getting boost jets for 12 psi, 2'5 or 3' catless hks exhaust and i have an intake on car currently. i also plan on getting a chip and tune eventually and downpipes when i change the clutch soon. but i dont want to get to big of injectors nor to small! is 370cc enough for the amount of power i will be producing after those few mods? what are some good brands of injectors? oem or no? i also am curious what i should change while i am in the plenum again. do i need injector o-rings also? my car has 59k on it, please help me ive looked everywhere and asked many people and i cant find any answers, your my last hope nicoclub! -Nick
