There are 2 basic types of injectors. Peak and hold(low impedance) and saturated(high impedence). Saturated take a small amount of current to open and stay open, whereas peak and hold take quite a bit more current to open and then very little to stay open. Peak and hold are generally a faster reacting injector(easier to tune for idle) but they will require a resistor box to be put inline. You can get one out of a junk yard off of many older hondas/acuras. I believe the biggest injector that you can buy that is saturated is 750cc.

 

UP!

 

if these were 1000cc i would buy them
