hi, i am a noobie, so no jokes guys. first here's my situation: I recently bought a turboed honda si (2000) and whoever built the car had money up the a$$. but they were running 16 lbs. boost w/310cc rc injectors. i don't know a whole lot about cars, but i am almost certain that the motor was running pretty lean. so here's my question. I am looking to buy some 750cc's and was wondering if my civic was high or low impedence. i know low impedence injectors need a resistor box, but i don't even know where to begin to look. although right above where the injectors plug into the edelbrock manifold, there is a small black box that's got denso written on it. the fuel line seems to run through this before it splits off into the four lines. here are a couple pics of the car and of the denso box and motor. thanks guys in advance.

 

16 lbs on 310's? :eh:
They probably jacked up the fuel pressure.

RC 750's come in high and low impedence. You can plug and play high impedence injectors directly in or you can wire a resistor box or inline resistors and run the low impedence injectors. Either way will work.

I like the random pic of the EVAP solenoid.

 

thanks bro.

 

Just to clarify, that box you posted has nothing to do with your fuel system.
