Nitrous Express is offering a $50 mail in rebate on its systems right now at www.summitracing.com plus free shipping. I scored an EFI Proton Plus system with 10 lb bottle for $369 shipped after rebate. One could also score a Nitrous Express Mainline EFI kit for $349 through these deals. That's dirt cheap
.

I will post pics and a review up when I receive the kit, as I did not find a whole lot about this kit on this forum, or even around the Internet.
I am interested in the Proton solenoid module, I think if done right it could really clean up the installation of a nitrous kit. One black box instead of two solenoids, fewer wires, etc.

I think Nozzle kits open you up to a lot more chance of user error since the user decides where to install the nozzle (and in what) but I wouldn't classify all nozzle kits as junk.Originally Posted by patin88z

The nozzle kits are not junk it just as good as a plate system,

I received the kit last night. The quality of all of the parts is excellent, I especially like the bottle with the built in nitrous pressure gauge. I will post pics up tonight, I am currently fabbing a bracket to mount the bottle in the spare tire area.
Can't wait to see Pictures....
I am going to turn this into a build thread as well as a general review of the kit. I am 28, I installed my first Nitrous kit when I was about 20. I no longer feel the need to rush through the install to go race on Friday night, so hopefully my quality of work is a bit better lol.
Here is my mounting location and bracket fab. I just used a 1" piece of square steel, as well as a few pieces of 3/16" steel bolted to where the spare tire and jack were mounted.

Here are the brackets painted:

With the bottle mounted:

You can see the Nitrous Express bottle valve in this pic, it's pretty sweet looking to be honest. It has a built in gauge port and is constructed well.

Next up I will be running the nitrous line under the car

3. Never said the kit was junk...just dont waste your time with nozzles. Step it up to a plate or DP-I

Why is a plate system sooo much better than a nozzle anyway?
It looks like a great system and the price is right!!!

You can push a 150 shot from a single nozzle I like how it mixes together in a fog,cause I ran both years ago with a paxton sn-93,the plate hit was very hard but the nozzle hit was nice.
Well I drilled a 3/4" hole in the spare tire well and ran the nitrous line under the car. I am trying to decide where to mount the solenoids now. I think thinking of making a little bracket and mounting them on the passenger side valve cover.

I see your point, my line of thinking was that the plate kits, particularly carb kits mount the solenoids off the intake manifold. I called NX and asked them, they said the vibration wouldn't be an issue, the heat could be an issue. I won't chance it and will mount the Proton box somewhere else.Originally Posted by patin88z

I mounted the Proton Solenoid box last night, this is the best location I could come up with:

I am picking up a schraeder valve removal tool today and will be hooking up the fuel line. I am also hoping to find a throttle body to MAF silicone adapter locally to get rid of the ugly accordion piece, if not where can I get a good one online?

Thanks man I bought the tool today and remove the schraeder valve. The fuel line included in the kit is about 3" too short, and that would be a very tight fit. I am going to have to find a way to make it a bit longer. I am thinking of adding an inline fuel pressure gauge, or coming up with some sort of 90 out of the fuel rail.Originally Posted by patin88z
Looks good man, also the tool you need is a tire value tool that they sell at the local parts store. So I am hopefully going to the track on Sunday, I want the kit to be operational for that even if I don't use it, although if I run a decent number NA I plan on running the kit.
I really wanted to keep this kit clean most of all. I see a lot of EFI installs where it just looks like braided lines running all over the place, I think the install is looking clean personally.
Here is a shot of my new MAF to throttle body connector:

Here is a shot of the entire system now:

So I have one question that is on my mind, the kit says the jetting is based on 50 psi. Stock TPI is 43 psi and I don't want to mess with adjusting my fuel pressure and retuning NA.
So since my fuel pressure is 14% lower than what the jets are rated at, should I be running a 14% larger orifice fuel jet to compensate?
I will most likely call Nitrous Express tomorrow to ask, I am sure I am not the only person to run into this...

I am thinking I may end up running my system this weekend if all goes well, I received this in the mail today:

It is the NX adjustable to 60 psi fuel pressure safety switch. Pretty spendy but I think it is worth it when you consider how much a new motor would be.
Edelbrock made a FPSS for $18 but it appeared to be on back order on Summit's site, plus I would have needed to buy a -4 coupler with a gauge port on it and those aren't cheap.
Nitrous Express said that 43 psi vs 50 psi is ok and to use the jetting recommendations that came with the kit
I will definitely be checking my plugs after the first few passes but he sounded very knowledgeable.

Any more pics and how did you splice into the factory fuel line?
How is the kit? I'm thinking of getting the same kit.

Sorry for the late reply. So I bought a tool at a bicycle shop to remove the schraeder valve from the fuel rail, and then I used some AN fittings I already had to build a -4 AN line off the rail. here is a pic:Originally Posted by monsterjam5000

Here is another shot:

Since this post, I wound up rebuilding the intake piece out of better components. I also bought a FPSS and have had problems getting the system to engage with the FPSS hooked up. So I bought a fuel pressure gauge and added it to the system, then decided to rewire a few things and thus, here we are
.Plus, my car was running 14.6's at 94.5. When I bought the kit, I thought I would be running 13.9-14.2 and touching 12's with spray, I didn't think I would be barely in the 13's on spray, so I decided to wait until the car picked up more ET NA before I sprayed.
