So I had a zex dry kit laying around and decided to put it on my 2000 z28. I'm going to run a 100shot. I plan on a Dyno tune once everything is installed. I currently have a single spray nozzle. Where should I mount it on my slp lid? Should I invest in a halo spray bar from nitrous outlet? Or will a single nozzle spraying in the lid be ok. Any info or advice on dry nitrous will be appreciated, thx
So you're gonna spray with no tune and no timing pulled? What mods, plugs, and injectors do you have?
No I plan on spraying with a proper tune.
Mods include slp lid, ls6 intake,228r cam, 3200 stall, LTs, ORY to cut out. Stock injectors and ngk plugs. I plan on changing the plugs for spraying. May upgrade injectors if needed? What's a good upgrade for injectors if I need them?
You can find good deals on here in the classified section regarding injectors. So many going turbo, seems like there's always a plethora of 42/44lb/hr injectors on the market. Just to reiterate on what HCI2000SS said, you WILL need injectors for a dry setup.
I would invest in the Halo Bar if I were you. I remember researching the hell out of it a few years ago. I doubt it would be all that expensive, and the distribution of the nitrous is going to be far better than you'll see from a nozzle. You could also post in the "parts wanted" section that you want one. Never know, one may turn up.
I would put our X series system up against any entry level system. The tune ups and power you will put down will really be untouched by that zex system. Not including the tech help we offer.
I would really recommend a wet system since you are running the factory pcm. You could sell that system and put the money from the injectors towards a new system that will be ready to go out of the box.
If you do not have Hp Tuners and you are not savy with it. The learning curve is going to be a lot harder than having a tuner throw in a good motor tune on the car. Where you can make the adjustments necessary (fuel jet) when the weather changes for the nitrous.
For a dry and to do it right, you will really want to have an aftermarket ECU and have the individual injector control.
You do need bigger injectors for sure. Also, for a good halo system check this out. It's designed to go in the lid of your air intake box, and can be hidden pretty easily. If you have any questions about it, let me know!

Would a wet kit not require upgraded injectors for a 100shot? Just wondering what's all entailed
This is a really nice system we sell that will work awesome for 100 shot. (Should be able to sell your zex system for a couple hundred bucks and pick this one up pretty easily, and not be out much money.) It would be very easy to install and the LS motors have a place to tap in for fuel on the rail. from the factory, so it would be a very easy install for you.
Really the only thing you have to worry about with your setup(on a wet system), is a big enough fuel pump to supply fuel for both the nitrous system and the motor, the injectors do not factor in. If this setup is stock, or very close to stock, you can add 100 on the factory pump with no issues.
Could you tell us a little bit more about your setup? Mods and such?
Also if you need pricing on this system or have anymore direct questions please feel free to shoot me a PM.
Another option. If you are going to buy a halo/plate/whatever, Why don't you pick up a couple noids(fuel and nitrous), use your bottle and line and piece your own kit togather. Im sure either of these guys will put togather a kit minus the bottle for you. I installed a Zex kit on an LT1 car some years back and didn't like it at all. Besides, by the time you buy a good set of injectors you could buy the parts to build a wet kit
How does that conversion to wet work? Would it use my current nitrous management unit from zex ? Sorry I'm new to nitrous and never have done a wet kit.
I would get rid of the zex box entirely.You can't beat our X-Series systems when it comes to bang for your buck! Or just buy the solenoids and a window switch.
We get alot of calls with problems from the Zex box, actually. Might try to sell your current setup and pick up a new system and you would probably only be out a couple hundred bucks. Mixing and matching parts can become a pain.
