I have a prelude with f22a1 engine and ive heard that installing higher rated injectors, say 370-380 or 450cc injectors, you do not need to wire in resistors with them because we have a resistor box already....true? and if so should I run the fmu still with 6 psi .thanks

 

What year Prelude? OBD1 and newer you need a resistor box, OBD0, you do not.

 

its a 1992, ,....so i wont need to worry about the resistors ?..........what u think about the fmu?

 

Yes, you will.

I think FMU's are Satan's way of tempting you with boost when his only plan is to destroy your motor.

 

So im screwed on both parts, install the injectors with resistors and dont do the fmu

 

I have a 94 honda prelude si and it has a resistor box. It has 240cc peak and hold injectors stock and I am pretty sure yours are the same.

 

There you go.

That's basically what I was getting at... if you have the resistor box, you don't need the resistors. However, I did ASSume Preludes also switched to saturated injectors after 91 (beginning 92), but ----, what do I know about Preludes? :P
