GTR injector?

Spstone · 12-28-2016, 06:56 PM

I see GTR fuel injectors for sale all the time. Is there any real positive for a NA car to go with these injectors, or upgraded injectors at all? I've got a M370 upper, Stillen Gen 3 CAI, Fast Intentions exhaust, and will be getting a ported lower from SoHo and a Tune and still trying to figure out my smog stuff to decide if I want HFC's, LTH's, or test pipes. I've never messed with any thing but carbureted motors so thanks for any help you can give me.

I wouldn't think you would see any benefit unless E85 is part of the plan.

No plan on E85, just trying to max the benefits of simple bolt-on stuff. I'm still learning all the ins and outs of tuner type cars and wasn't sure if there was any benefit so figured I'd ask the experts on here.

Adding larger injectors to a bolt on 370z won't change its power output by very much if any at all. (E85 is a exception but even that wouldn't add much power to a bolt on Z. Your car can only suck in so much air with bolt ons, and your stock fuel injector is large enough to supply that demand. Hope this helps!
