hi i have a set of JDM H22 injectors with a resistor box. i got them off a JDM manifold i had laying around. all i have left is the 4 injectors and the resistor box with the plugs and a little tail of wire on each. is there any way to tell which OBD they are how many CCs and wheather there peak and hold or saturate????
thanks

 

Check the Ohms of resistance between the two injector pins/wires. If it shows 2.5-3 Ohms they are Low Impedance (peak and hold) and will require the resistor box. If you see 11-13 Ohms then they are High Impedance (saturated) and will not require the resistor box.

As for finding out what flow rate they are that is a bit harder to test yourself. If you send them out to be cleaned and flow tested they will be able to tell you exactly what they are. Other than that most of the 92-96 peak and hold H22 injectors were 345cc. The later high impedance injectors were in the 280cc range.
