Zex wet kit.

[bobby2002s2k.]

Well I just bought the Zex wet kit with all the extras bottle heater, perge, Remote opener and traction control.Figured that if i'm goin to do something that i know most of everyone hates on here I would do it right,lol. Kit comes with 55,65,75 shots. The Zex seems like the safest kit and I can 4see its not goin to get used much. Anywho pics after install if i figure out how to post single pics.lol.

Very interested to get your impression after you've used it a few times...Always an entertaining notion to have some quick HP in your back pocket ... or trunk... as the case may be.


pls let everyone know how it works out..

thanks, kevin

Yeap 4 sure man.

I've got a dry NOS kit that I've tried to sell(brand new). It puts out about the same amount of power. Let us know how you like it and I might throw mine on. Just don't forget to get some colder spark plugs and watch your a/f ratio. Also purge the lines before you use them for the first time. Sometimes crap gets in the line before you install it and it'll screw up the nitrous solenoids and possibly go into your engine. Good luck with the N20!

Well thats the good thing about this kit I dont half to worry about to much of that, has it own computer that checks everything and if something gets to dangerous (high or low) it cuts off the no2. You should check it out.
• ZEX Nitrous Systems have an advanced, patented feature called "Active Fuel Control". This feature monitors nitrous bottle pressure and adds or subtracts enrichment fuel so the engine never runs too rich, or too lean, when you engage the nitrous system.
I havent checked into the spark plus yet I'm thinkin i may have to got to a 1 colder set, but i'll keep yall posted forsure.

[D1sclaimer]

All the zex active fuel control system is is a box with the solenoids and a vacuum system in it to determine if somethings not right. Most other kits like mine have this, just without the fancy box and advertising. You bought a great kit though.

[bobby2002s2k.]

Got it hooked up. Very clean install. One Problem first test run i blew a rod out the bottom of the motor!! Naa, Just jokin,lol. There was a problem although. I had to have a new Perge line fabed up(the one in the kit is only 4 feet, needed 6) and as soon as we turned on the Bottle the line burst. So its goin to be tomorrow before I can get another fabed up and connected.

What hp jet will you be using? I was talking to a guy from s2ki. Hes got the same dry kit as me, but is running a 75 shot with only a test pipe. He said he only uses it about once every few weeks. I think thats a little too big of a shot.

[bobby2002s2k.]

I"m starting with a 55 shot because I dont have to retarted the timing. I'm goin to move up to 65 or 75 after i get the MSD Retart thing so I can stay safe.

[D1sclaimer]

Good choice. Im gonna start with a 50 also.

The photos after the install sorry it took so long.

Looks like your setup is pretty awesome. Have you raced anything good. The only thing that I would suggest is positioning your bottle a different way. Since its sideways, the siphon in the bottle won't get all of the nitrous when you're accelerating. But since we're only running smaller shots, it doesn't matter as much anyways. Great job setting it up.

BTW, did you run your line to your bottle under the car, or how did you get it to the trunk? Any drilling involved?

[bobby2002s2k.]

Naa, no racing yet. need to get it to a track sometime this summer. I drilled a hold in the trunk just big enough for the line to fit and used a like factor rubber grommet to seal it off. then ran it along the bottom of the car.
I also had my doubts about bottle pos. but like you said it shouldn't be much of a problem with the little shot and as long as the heater is on.

i have this kit on my ap1 with a 75 shot on it. any larger then that an it jumps your timming. you will need kpro or something like that. but so far i have sprayed the shit out of mine. i dont recomend it but i have a built head an a new bottem end ready. the only problem i experenced was a snaped axle an i blew the shit out of my rear end was fun tho. but have fun with it . be safe

Looks really good bobby. You got to take me for a ride with some nos shootin when we meet up in April.

I just installed this same kit in my car last weekend.

The NMU (Nitrous Management Unit) houses the solenoids along with a switch thats calibrated to your position sensor on your throttle body. It's a peddle to floor activation setup. Real easy...

The NMU also has a safety system... If either of your inlet pressure's drop, Fuel or Nitrous, the NMU will kill the solenoids to prevent potential damage to your motor.

here's a PDF if anyone is interested in the Kit http://static.summitracing.com/globa.../cca-82021.pdf

PM if you have questions or post here

After a good wash


My airbox has to go!!!


The airbox does hide it well though...

Bottle is mounted to a board that use to have my amp mounted to it

Hey Dude,I have a APEXI neo piggy back computer.I see in the instructions that you shouldn't use the system with that set up.Any input on that?

[Gammit]

You have to look at it the way ZEX does... They wrote this manual with one thing in mind... reliability. They do not want your motor to blow with their product installed on your car. Thus, they inform you of all saftey precautions and general do's and dont's. The majority of their testing was done on stock motors with this kit. So, naturally they are going to advise against it. I dont see in the manual anything specific about the Apexi NEO or any Fuel Controllers. I would do some more research and find out if anyone is having problems running nitrous with your setup.

Probably the most important part to remember:

Start with the lowest power level nitrous jet and corresponding fuel metering jet. Make a full throttle pass and read the plugs. Not enough nitrous/too much fuel results in a sooty, black plug coloration. This coloration means that the fuel mixture is too rich. Too much nitrous will exhibit high heat in the form of a bluish or rainbow-like coloring on the plug's metal surfaces. This means you're engine is about to, or is, detonating. Check all plugs! not just one or two!

Any updates on this? how did the wet kit work and how long have you been running it? how big of a shot are you running? do you think a wet kit or dry kit better... anyone running a direct port kit?

I been waiting for some progress on NO BLOWN MOTORS!

You can use the AFC Neo, but I'd turn corrections off when spraying. Changing jetting is the best way to tune nitrous.

i have the direct port wet zex kit its nice you can go to a 75 befor the timing retard becomes a problem i have thew 75s in mine love um till i blew the ring an pinion to peaces lol well it was sitting for a year i just got it back togeather i think i might keep the switch turned off lol but its so fun. let me no how you like it after you use it a few times

[Gammit]

update: since I put the ZEX wet kit in ive had no problems with it.

However, the bottle did get warm one day and it must have blew off in the trunk while i had it parked at work. I checked my bottle pressure before heading home and it was at 300psi. I thought i had a leak so i check the the fittings to see if any of them were frosted over... none found. Would have been nice to see it blow off!

Im running the 55 shot and i want more! Is anyone running the 65 or 75 shot for this kit on a stock motor??

Was this the same day you got your bottle filled? or within 24 hours? If so, let it sit in your garage in a cool spot for about a day. If it heats up fast like that, the safety valve will open.

Edit: Im looking at your install pics. Why did you throw the nozzle so close to the filter? Wet kits need to be sprayed as close to the throttle body as possible or you get unequal cylinder distribution and the back cylinders will run lean while the front run rich. If you ran a dry kit, that'd be a great spot though since you want a dry system to atomize through all of the intake.
