i have a 91 hatch with a jdm zc. i am in the process of boosting, i have a set of rc injectors, they are sl4-440. they are saturated. i am confused on what to do. i know that 88-91 are peak and hold with resistor box, if i want to put the rc's in do i remove the resistor box and wire them as if theyare obd1 or do i just put them in normal for obd0with resistor. i guess what i mean is should i remove the resistor box or not.

 

yes remove the resistor box, I am almost positive all saturated injectors are high impedence which basically means they don't need the resistor box. just check the resistance of them with an ohm meter and high resistance(12-14ohms) means no resistor box, low resistance(2-4ohms) means you need the resistor box.

 

I would just sell the rc440's for $200 and buy a cleaned set of dsm 450's off ebay for under $100. They will plug and play with your stock injector clips(unlike the rc's) and will work with the resistor box. They are also oem injectors so the reliability is actually better than the rc's. I would not remove the resistor box
