I got a 93 hatch, b18c1 headwork done freshened shortblock etc.
Now I want to go e85 but I'm lost on the type of injectors I need? stock fuel rail and injectors tuned on neptune, it started life as a 95 gsr, still have stock rail injectors etc have a walboro 255 aem fpr though.

I don't know if I need to wire in a resistor box or if their is a certain injector style I should be going with or brand, I was thinking 650s going to be e85 and 60-80 wet nitrous kit and retune.

Please help I've searched and just get more confused, I understand how they work just not what I need to order.

 

You only need a resistor box if you run low resistance injectors (2 to 5 ohms).

The injector size you need is dependent on the HP you want to make.

Short & sweet: for gas N/A [FWHP] * .5 / 4 * 1.15 = optimum injector flow rate in lb/hr
for E85 N/A [FWHP] * .7 / 4 * 1.15 = optimum injector flow rate in lb/hr

As long as you're running a wet nitros kit you don't need to factor that into your injector size. You DO have to factor that into your fuel pump though.
