I have a 94 Nissan Pathfinder 2wd, V6, 5 spd. I was told I can run the Infinity J30 injectors in my motor and it :biggrin: will increase my HP and fuel economy. And ideas??

idk about that i thought the 94 pathfinder had the vg30e(that being said i think you want to post in the z31 section) so i dont see the injectors making a difference. UNLESS the pathfinder had smaller injectors, so im not too sure on that one.

I'm pretty sure the injectors in your pathfinder aren't even the same shape as those used in the J30/300zx engines. Even if they were, the CC's are different and you would probably just end up running rich. You definitely wouldn't be getting better mileage

yea it does have the VG30E, I posted here bc I had not looked through the forums yet. that was my bad, so basically its not looking like they will work so I might as well order a factory replacement. Oh well. Are there any other injectors that will work in that motor that I could swap out with?

For whatever reason, the injectors from your pathfinder look like this:

And most of the injectors from other cars (J30, 300zx, Maxima, Altima, etc.) look like this:

However, it looks like newer injectors from a VG33E engine (found in newer pathfinders) will fit. In order to do this you would have to swap out all of your old style square connectors to the newer style oval ones (you can find these in almost any 94+ nissan car/truck at the junkyard). There's 2 wires for each connector, you just cut the old one out and solder in the newer ones. These will also last alot longer than your current old style ones.

Whoever told you this has absolutely no idea what he/she is talking about, please do not take any more advice from this person.

Injectors just by themselves don't affect horsepower. Also, you would have to have your ECU flashed to accommodate the different characteristics. People go to larger injectors so that as they do mods and their engines get hungrier, they can supply more fuel, which will lead to more power.
