I have a 2002 Civic LX Turbo and currently have 340cc RSX-S injectors in my car that ar ebeing maxed out at 10psi. I am thinking about getting some RC 550 injectors, but needed some clarification on what exact ones I need. I know there are high/low impedance injectors and peak and hold/saturated ones and i was wondering which ones i need to get for my car. Thanks

 

Either would work. You would have to wire up a resistor box for peak and hold injectors though. If you don't want to do that, the saturated would do just fine.

 

peak and hold require a resistor box

for your year model I am thinking you need saturatued
