I got some 440cc injectors for my OBD-0 crx that i am turboing, i was woundering if i need the resistor box with these mitsu. injectors, they came out of a 99gsx or just run them with out it?/

 

yes, youneed one if i remember correctly

 

dont obd0 CRX come with a resistor already>?

 

they do come with it but i thought it was because of the high voltage needed to be regulated, i dont know if the mitsu's do?

 

The best answer is to mesaure your currently running injectors. In Hondas, they will be 2-4 Ohms for Low Impedance, or 10-12 Ohms for High Impedance. Most blue topped DSMs are low impedance, they will work without a resistor box, if your car already has low impedance injectors and a factory resistor box (which were often used on the Si models). If you have high impedance stock injectors, and want to install low impedance DSMs, then you need to add resistance.

BTW for OBD0 cars like the 88-91, high impedance injectors were used on most models, while the Si always used low impedance and a resistor box.

That help?

it was a dx, now with a b16a and has been converted to the four injector set up, (HA SPORT) so i guess that it is wired for the Si, and they are the blue top dsm injectors. i think it should be ok to use it?

 

In that case, I would definitely measure your current injectors, and match their impedance. After doing swaps and mods, you really don't want to take chances....

Here is a link to show you just what to measure....
