1990 300zx n/a injectors

[Vilmenay]

What's the highest injector size I can upgrade without having to flash the ecu on a 90 n/a z32?

[evildky]

the easy answer si taht you can't, the ecu is calibrated to work with one specific size and thats it, but upsizing the injectors isn't going to do anything for you without lots of other supporting mods, including an ecu flash

^ exactly

More fuel is not the answer yet. There are several other mods that you should think about before upping the injector size. Once you reach the point where there are no many power adding or freeing "easy" bolt on's (intake, exhaust, headers, mid pipes, ecu, flywheel, driveshaft, crank pully, ignition) then it's time to start monkeying with the fuel delivery.

DUDE are those z33 wheels or g35? they look real sexy!

[evildky]

stock n/a injectors can supply enough fuel for every possible n/a bolt on, unless you add a turbo or no2, your fuel injectors are big enough

even with a 75 wet shot my injectors have no problems -- I doubt there are many NA owners that have upgraded their injectors.

Agreed with everyone in this thread. There is really no reason you need to upgrade injectors in the N/A Z. The stock injectors can handle all the bolt-ons you can get for the N/A Z.

BTW phantikz32, honad has the 350Z wheels.
