I was Wondering what the injector impedance is on G35's and 350z's ?
Does anyone know ?

Thankz

 

Impedence is an alternating current term, with a DC system RESISTANCE is the correct term. Since each injector is a solenoid, Inductance might be specified, also.

 

Well, I just know there are two MAIN injector types. High Impedance or Saturated injectors which are the most common; and peak n’ hold injectors which are Low Impedance. The latter are normally better for performance (or so I read). I have always head of them being grouped in "Impedance". Sorry if I asked/worded my question wrong, and thanks for correcting me. However it is all the same really, just another way of saying it. People call the VQ35DE I have under my hood a motor, but by definition it is a engine. The terms are synonymous, much like these. So I think everyone knows what I mean. I would still like to know which injector type the VQ35DE uses. So Please Help if you can. Thankz.

Below are a few sites that miss worded it also.

PS: I do believe you spelled it wrong. "IMPEDECNE” = Impedance

 

Just shows that the people who describe parts or write marketing copy are not engineers. Impedence can only be measured with a induction bridge whereas resistance is measured with a VOM.

True there are 2 types of injectors [the solenoids inside]: saturated and peak hold

Nissan has used the saturated type ~~12 ohms resistance for about 20 years......for a better idle.

The peak hold type open faster [place more stress on ecu transistors].

But there would be no difference in the performance of the two types. As air flow into engine by external atmospheric pressure is the power limiter not fuel flow.

Thanks for answering my question. I was wondering this because all the prices I've seen on injectors that are labeled for the 350z/g35 are high compared what I’m used to seeing.. So I was wondering what main type of injector they used, so I could know what would work and what wouldn’t. (Without having to add resistor packs or other modificationss.) After knowing which main type of the injector, the other things to worry about are the size of the injector (physically) and the plug type. (Of course you must pick a size in lbs per hour or CC to fit your needs also.) So thanks for the help. Seem to be rather knowledgeable on the QV35DE power plant.

I mean 190 per injector seems high to me.

Oh another question, Do you know the size of the stockers ? In cc ? Thankz
