q45 injectors...need resistors?
As the title implies, do the Infiniti q45 370 injectors need some sort of resistor to work in a sr20? I've read where some say yes, and some say no. So who's right?

Picked up a set for cheap, and they tested good. They're the brown tops. I'd like to use them on my other de.

What year Q45? If its the vh45de, it uses the same injectors as the 300zx TT, which are high impedence and you would not need resistors.

A 96 I believe.....maybe 95. It was a small V8 IIRC.

Did you have them flow tested? I have a set of brown top Q45 injectors myself and am skeptical about them being 370's.

My friend owns his own shop, and hooked each one up to check function and pattern. Didn't have a way to measure output. Plus I don't have anything that will measure that accurately.

Conwrath, how much do you feel yours put out? If mine can move at least 320cc, that will work for now.

Mine are putting out nothing, as they are in a box.

I guess I'll just have to bite the bullet and send them out to be flow tested.

I'm not really up to speed on the Infiniti line. But I figure they can't put out any less than 260cc. I'm going to use them on a de (no turbo) anyway.

Cool, let me know what you find out!
