zex nitrous

SGT BRAD · Post by **SGT BRAD** » Thu Mar 30, 2006 8:49 pm

i am going to eventually get nitrous after my build is complete. i have been leaning towards the zex kit b/c of its simplicity and safety features. but, i was wondering if anyone had anything bad to say about it. anyone able to give a heads up comparison to the nx kit? thanks.

got you covered. i had a nx kit on first. had two solenoids go out in two years. It is massive on wiring. Two relays, power and ground for each solenoid, four wires on the relays, toggle switch, and wide open throttle switches all have to be wired also.

GET THE ZEX

Three wire hook up. mount the solenoid box and thats it electrically. power through toggle switch to battery, ground, white wire to tps. After hooked up you smack the pedal to the floor three times til the box sees what your max tps voltage is. ( usually around 4.8 volts. )

Both kits hook up the same fuel and nos line wise.

I install these kits at one of my jobs and i would say around 4 hours to put the nx kit in and under an hour to put the zex in especially in a neon.
Pm if you need any pics , diagrams, or whatever

part number 82021 for purple and 82021p for polished bottle. about a hundred dollar difference for polish

i've got a dry zex kit i need to get rid of. It has had 1 bottle ran through it. I'd take $325 + shipping.

btw were you running a dry or wet zex kit? thanks.

wickedneonrt · Post by **wickedneonrt** » Fri Mar 31, 2006 10:35 pm

wet in both.

i am new to no2, but have been advised to stay with a wet kit. but, i am not going over a 55shot so i am considering a dry kit since the cost is less. later i'll possibly convert to a wet kit, or maybe just spring for the direct port kit if i get hooked on the "juice." if dry is really a bad choice with a small shot i'd sure like to hear the rationale. thanks.

ive always heard that zex has very crapy nozles on their bottles. any experience with this. i have heard many people say that they would sort of have a "bad shot" or a lag in the nitrous with the zex bottle and as soon as they switch to a NOS or NX bottle it solved the problem.

SGT BRAD · Post by **SGT BRAD** » Sat Apr 01, 2006 11:57 am

the story i got from some people in the know is that the zex valve doesn't flow quite as much as the nos. not sure how it compares to nx, but i think it is definitely something with the zex kit. however, the zex kit sounds basically fool proof with the control module. if i were a hard core racer then the better flowing, more tuneable nx kit might be more appropriate. for me the zex sounds like the way to go. now to find a bargain on a wet kit!!!

Noticed that too with my Zex bottle. But that was rectified when Santa's Little Helper dropped off a 20lb Cold Fusion Nitrous Systems bottle. Stay with a wet kit. Been running a Zex kit now for over 2 years. I would suggest you put a RPM window switch and relay in-line with the TPS wire to the control box. Set the RPM switch to close the relay at 3000rpms, and open it at 6200rpms. Hit the gas too early, or run it too high (hitting the rev limiter) things tend to go boom.

thanks for the input. i am sold on the zex kit. it'll have to wait until after the motor build. however, that is getting closer to being finished. just have to gather the bottom end and we're good to go.

This also may be a n00b question, but where's a good, well priced place to buy ZEX kits...besides the ZEX website of course.

and as 03neonrt this is a noob question also lol, what would be best to run in an 04 sxt atx?

03neonRT · Post by **03neonRT** » Mon Apr 10, 2006 8:52 pm

Lol i know a enough about turbo's from lots of research to know what i'm talking about (most of the time) but i dont know shit about nitrous...except some basics about the tech.

Definetly do the wet. sometimes its impossible to find a upgrade from dry to wet without buying a whole kit, then you have to buy the pieces seperatly. You'll save more money and hassle by getting the wet first.
Another thing to watch for is make sure there is someone in your area to fill the nitrous. A lot of people think the bottle comes full and of course it doesnt. There is not a lot of options where i am for nitrous refilling places but i do have one and thats all i need. Im sure theres more somewhere. Just dont want you to get stuck having an empty bottle.
Havent heard about the leaking nozzles thing but zex is a great company customer service wise. They are owned by comp cams. If there is ever a problem with their parts they are easy to get warrantied. I sell their products and kits at my part time and have never had to send anything back that i could recall.

OK, so after looking through the Forced Induction threads as best as i could...what is the overall opinion from people on the maximum amount of nitrous to use safely on a mostly stock 2.0 HO motor? (55,65,75?)

dinetuner · Post by **dinetuner** » Mon Apr 17, 2006 9:31 pm

just depends on how long you want your motor last and how much you use... dinit mopar mag run there "rental" neon with a 100 shot? i would personally say a 50 shot is a good solid number that ive seen run for years fine.. anymore your looking at rebuilding your engine...

i ran a 35 at first and blew a piston ring sky high. unfortuanately that happened with 15000 miles on the car and when we got in the motor i we couldnt find any remenents of the compression ring in the oil pan or anywhere so either it somehow magically shot out or it wasnt installed correctly in the factory. Its hard to explain but one of our rings is a three piece ring and two of those pieces were gone. whether it was nitrous or just somehow done wrong in the factory who know. My car did always lose about 1/2 qt. of oil aweek til we rebuilt it.
I'm now running a 55 shot but with lower compression je pistons so it safe but mainly because of compression being lowered for my turbo. i'd do the 35 but like most people if you have the ability to adjust your car to go faster with no money you'll wanna keep uping the shot til something does go boom. Then its too late. just do it right . run colder plugs and high octane ( which r/t's are suppose to do anyways

what about the zex direct port nitrous kit. at around 600.00 it seems to be a good deal. no lean or rich cylinders. everyone gets the same. hmmm...
