Need Help Please (Fuel Injectors)

I want to upgrade my fuel injectors but I'm not sure which fuel injectors my z comes stock with. Is a 2005 Nissan 350z Touring Convertible 3.5l V6 Manual. Any help please? What cc and mm are my fuel injectors?

I could be wrong but I think that upgrading the injectors would not gain anything for you unless you have much more power than stock (such as forced induction)

Hmm. I was told my many people getting better fuel injectors (such as going from 60 mm to 80mm fuel injectors) will make my z faster. Makes sense being as the more gas sprayed the more it can use..hmm.

Gotta say the same thing.

Wonder why you need an injector "upgrade"?

Maybe start by getting a larger or ported/polished throttle body?

What other mods on your engine?

Have a plenum spacer?

In my "younger days", I slapped 2-4's on a stock V-8.
The engine did not need or could not handle all that fuel(food).

Change the cam etc,it will.

Stop listening to "many people"/friends.
They usually don't know jack...

Sorta funny...

no, upgrading your injectors will do nothing without major major modifications. I ran my procharger @ 8psi with their fuel setup on OEM injectors and made 375whp.

How much money do you have and/or what amount of horsepower are you thinking of?
