you can use the stock injectors if you're running the 6psi pulley. If you're running the 8psi pulley then you can use 290 or 310 injectors without using an FMU. HTH.

No FMU with 8 psi of boost? Whats the matter with you?

Are you serious? I feel bad for people who take peoples advice online.

At 6psi just stick with the stock injectors. Get the JR map mod if your having tip-in detonation issues.
Now, with 8psi and let's say 310 injectors you will still need an adjustable rising rate fmu but like a Cartech 2025 or something.
You definetally wanna ditch the Jackson Racing FMU when you run those injectors because the rise rate is a non adjustable 5 to 1.
For those who are math impaired (joking)...picture this. Idle fuel pressure of 50psi then add (5 multiplied by 8lbs of boost).
50psi idle plus 40psi equals a max of 90psi.
And if your using the JR intank that's gonna be kinda risky cause if I remember correctly it tops out at 80psi.
So 310 injectors plus 8lbs of boost plus a cartech fmu set at like a 3 to 1 rise rate equals better.
And for the two guys argueing your both kinda right. Yes you need an fmu but you definetally wanna ditch that JR one and I think that's what MouhadIb probably meant. I think.
Anyways C-speedracing is a good site with lots of good info is all I know. (bump for MouhadIb).
