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.

[slowrodent]

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

[bobby2002s2k.]

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.

[D1sclaimer]

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.

[bobby2002s2k.]

[bobby2002s2k.]

The photos after the install sorry it took so long.

[D1sclaimer]

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

[sonic]

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

[Gammit]

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...

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!

[Snafu4286]

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?

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.

i have the 75s in mine i just took it out after rebuilding it i loved it so fun i ran them on a stock moter for like a half a year the only problem i had was the rear end sucks

I've had many fills before that day... it just got hot sitting in my trunk... and yes the safety valve opened. Theres no cover parking or a place i can store my bottle at work.

The nozzle is as close to the TB as i could get it with out putting stress on the lines and fittings at the NMU. The lines arent long enough. plus, i dont want to drag the lines over my belt.

[Castanza_AP1]

what wire on the tps are yall hookin up to

[playingmilitary]

when installing a wet shot of nitrous were did people conect to the fuel. have a nitrous express kit. i have the botle mounted and the location of the syliniods ready just not sure were to get the fuel from.

[DirectPortJuicedS2K]

AEM UEGO
Marshall Nitrous Bottle Pressure Gauge
Custom Nitrous Switches
Zex Direct Port Kit
Zex Bottle Opener
Blue Earls Elbows
Zex Purge
Zex Bottle Heater
Zex traction control window switch
Denso IK24 colder plugs
Dynotune lean shut-off switch = BEST THING YOU CAN BUY FOR YOUR CAR IF YOU ARE RUNNING NITROUS, SHUTS THE NITROUS OFF IF IT SEES ANY LEAN CONDITIONS.

Everything cost my about $1500 or so, free labor from myself

Granted i'm only 20 years old, i been running nitrous for 4 years. (First on my 05 Accord) I started running nitrous when i was 16 and never had a problem. My cousin was running 100 shot on his E46 so we decided to juice my accord as well. The direct port kit in my S now was the one straight out of my accord. I bought the kit and all the accessories new, although everything was a lot cheaper 4 years ago. Nitrous is not what kills car, people who dont know what they are doing kill cars. I been running this setup on my S for well over a year now and have no problems. A/F ratio stays consistent at 11.5-1.

I frequently run compression tests, and my most recent one showed 240 PSI in EVERY cylinder, which is perfect. I was running 75 on 93 pump gas for a couple months and the occasional 100 shot when i would fill her up with 100 octane. For the past 3 months or so i been running about a 110 shot on 100 octane and put down 318 whp and 284 wtq. This is stock fuel pump, and no tune. I pulled the plugs right after the first 110 shot pull and the plugs did not show any signs of detonation.

All in all, if you have a brain and about $1500 you can put down these kind of numbers. The car feels AMAZING. A lot of big turbo setup dont even put down the TQ this thing does on the Juice. My car puts down 212 whp by the way without nitrous. I also do NOT recommend anyone running nitrous if they cant install a setup themselves.


If enough guys are into a DIY, let me know...

[hammerhead300]

I'm hoping to go to nitrous before long. I know a guy who has a NX wet kit he'll sell me for $350 shipped. I'm a bit worried about going with a wet kit, because I've heard a lot about intake pooling destroying engines. What do I need to do to prevent that?

[PRB2000]

whats the diff between wet n dry, or direct?

[turbosix]

simplly put:
dry = nitrous is injected only, the stock fuel system supplies the additional fuel pressure via the fuel pressure regulator upping pressure when you spray
wet = nitrous and fuel are injected (see the nozzle pics above), the stock fuel supply still provides the extra fuel instead of the stock system upping fuel pressure to deliver it through the injectors

direct port just means instead of using one nozzle before/after the throttlebody, you're using oen nozzle per cylinder, as seen in the pics above with his nozzles in the intake runners.

[PRB2000]

which method performs best and which is safest?

[rodrodriguez760]

what spark plugs are you running on nitrous. i want to go with a 75 on my ap2 but dont know wat kind of sparkplugs?

[D1sclaimer]

go NGK 7173 gapped around .037ish. Whatever around there to your liking.

[turbosix]

dis, you ever use iridium plugs under spray? they're good for high boost apps figure spray would be no different..

[D1sclaimer]

No point in using Iridium. With nitrous you want to pull the plugs and put new ones in after a couple bottles to make sure everythings running right. Alot of people don't do that, but your plugs tell you how you're running and issues will show on the plug if issues are starting. Might as well throw in new plugs when you take the old ones out.

Only reason to switch to iridium or platinum would be to run them for more mileage IMO. This may be complete BS, but the general consensus from the big nitrous drag racers is that iridiums and platinums do run hotter than their copper counterpart even though they're rated the same. They run a little hotter so they don't foul as early as coppers. Also, nitrous will weaken/eat platinum so platinums are highly discouraged.

Coppers are 8 dollars total for 4 plugs for me at Advance Auto Parts and outlast what I want out of them.

Copper also scientifically has more conductivity. Some people claim that coppers don't hold power as long because they carbon foul quicker. When I'm spraying, it takes/eats off the carbon so it doesn't matter.
Electrical conductivity of Iridium: 188.679 1/mohm-cm
Electrical conductivity of Platinum: 94.34 1/mohm-cm
Electrical conductivity of Copper: 595.8 1/mohm-cm

[turbosix]

mileage was basically my reasoning. platinum is a no no in boosted cars so i would definitely not use them in a nitrous setup
