What injectors fit?

[ross932c]

I have read all the posts, and I know this has been talked about to death like everything else, I just like hearing opinions and expert advice before I spend my hard earned money.

I have a 94 N/A with compcams, Cold air intake, straight through exhaust. I realize I need more fuel and was looking into injectors as my next purchase. What size shoudl I go with? I was thinking the 390's from a A/T Turbo. Will these be ok to use?

Thanks for your input

I would first upgrade your fuel pump and filter and get a FPR. You then have the choice of increasing the fuel pressure. You have then killed two birds with one stone, you have done your preventive matnance with changeing your filter and you have now an upgraded fuel system.

Before you start any of this tho, I would get atleast a wide band and SAFC (or simular tuning capabilities).

But if you must upgrade your injectors, I would find some after market ones for NA. The reason being is that the turbo injectors are called Peak and Hold (aka low impedance) and yours on the NA are called Saturated (aka High impedance)

But if you want to run turbo injectors (low impedance) on your NA, you will have to install some series resistors.
