[gsrteg]

Hi! im new here but have ben on here for a very long time, love the community! heres my problem. My 300zx is missfiring terrible, has ben sence i bought it, 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

If you are paying for an upgrade and replacing all 6 I would go for some bigger ones, like I said in your other thread go new style and solder in some new pigtails, you will never know how thankful you will be if you do this because you won't ever have the fuel injector corossion BS issue again.

Just remember, you go bigger you have to upgrade the ecu... I know you said eventually.. But your car wont run without the upgrade
