Hey everyone, I am trying to find out if anybody can tell me for sure what these injectors are? I was told they are Precision 550cc injectors, but I don't know if they are or even if they are low impedance or high impedance :/.. I would like to find out so I can finish my build. Also, there aren't really part numbers on these, but I can look again or take more pics if needed. Any advice would be greatly appreciated.

 

they deff look like Precision injectors. but to see how many cc they are, your going to have to get them flow tested, and to check if its low impedence or high, you'll have to use an OHM meter. connect it to both pins in the injectors, and if it gives you between 1-4ohms. its low impedence. if its 10-14ohms then its high impedence. hope that helps.

 

awesome, I appreciate the answer. I just wanted to make sure my friend had told me the truth, only bad thing now is I don't have an ohm meter :/

 

You can get one for like 10 bucks or go to an auto shop class room. Go to sears use one and return it. Or google ohm meter.
Or maybe maybe one might pop up some day so maybe just hold your breath?

 

You can get an ohm meter for 3 bucks at harbor freight. Go buy one.

 

cool, autozone here said they didn't carry them.

 

Well, I finally found out that these are Delphi High Impedance 550cc injectors.. found the part number on the top of the injector where it was super hard to read. Now I am going to get them tested to make sure that they still flow well and try to get my turbo d16 finished.

 

high impedance is a good thing. it means you dont need a Resistor box! yay!! ha. good luck man.

 

yeah, I am happy.. was worried I was going to have to get a resistor box and wire everything in, but when I found out they were high impedance I was excited, because now I don't have to do wiring and all, and I can get my built d16 with the turbo on it soon. Thanks
