I have a mate with a BA that wants to put moddified XR6 turbo injectors on his N/A XR6. The car is pretty much stock ATM all it has is the SS induction and soon to be put on an SS throttle body.

Would bigger injectors make any difference in performance, cause I thought that you only add them when the engine is starving for fuel. You only need them with high horsepower applications :?:

Any info would be great

adding bigger injectors means the tune has to inject for a lesser amount of time to get the same mixture..

You only need to add new injectors when, as you've said, its starving for fuel... which it wont be.

I'm pretty sure you only need new/bigger injectors when you go turbo or supercharger.. not for NA.

tell him to get the injectors though and give em to me!

Yeah I'm still running the stock ones. 180 rwkw is about the upper limit you can get from them - I'm at 175 :lol:
