I have only one nozzle that came with my Zex. It's a .46. Guy said it was a 100 shot. Any idea? and what size would be a 75 shot?

I searched but didn't find anything. Would that be the nozzle kit they sell on the Zex site for like $20?

Thanks Dave. I'd probably find them on a site that sells nitrous supplies but I am exhausted so I'll look in the morning if you don't find any.

Yeah, no problem. Thanks that helps. Seeing as I never got any documentation. I think I can grab some off their web site though.

Those are the correct jettings. The Jets from some of the others are a bit different. You can purchase the jets directly from ZEX if you choose too!!!!

The size may be the same number but the necks and how they fit are a bit different.;)

I'll just get the .40 and .43 for now since I want to go down to 75 until I can work on the engine more.

The jets from the different zex kits are different as well. the 55-75 kit is different than the 75-125 kit. So the 75 shot in both kits do not use the same jetting charts.

For zex kits you can also use jets from NX. I got my jets from ZEX, but their sizes are limited when you really want to fine tune your air/fuel via wideband. You cannot use jets from NOS, Compucar, Edlebrock, Nitrous works...ect.ect.

zex and NX meassure their jets in thousands of an inch (.017, .045). NOS measures theirs by drill size i believe, so a 32 jet is a #32 drill hole. You'll tell right away because the NOS jets are huge.

Just a heads up.

Fast SC 92 is correct.

The earlier kits, which mine is, initially came with the other jets and was adjustable only from 55, 65, and 75 and the 75 HP jets are different than the updated settings from 75-125.

I have both sets so I can now run anywhere from 55-125.

I'm assuming since there is a 100 shot nozzle in there now that I have the 75-125 setup. I ordered from Zex's site. Since I only needed 2 jets. They didn't have a choice of jets for kits so I guess they no longer sell the older style?

nitrous jets are nitrous jets. There isnt a set just for kit A or kit B. My point was that the zex kit 55-75 uses a different jetting chart than the 75-125 kit. An example of that is the 75 shot for the 55-75 kit (#82011) is .038 nitrous .032 fuel. And the 75 in the 75-125 kit ( #82015) is .040 nitrous, .043 fuel. Each kit can take whatever you want to put in there. You could have the smaller kit and add a 200 shot if you wanted.

Like i said, just trying to straighten out some facts.

Is there a way to tell what kit I may have? The only number on the controller is the patent number.
