nitrous newbie help !!! well not too much of a newbie
Well, I have been curious about nitrous for some time now. I have decided to get a small 50 shot wet setup on my car. I am on 1 step colder plugs and will go to 2 steps colder once I put in the spray.(good idea?)
My research took me to ZEX, I like the simplicity of their install with the zex box.
However this is where I want to get creative, I want to start spraying only after out of first gear, I do not want to spray 1st gear and I want to spray only from 3000rpm - 6400.
I know that I can use a window switch to spray from 3000-6400 and probably just arm the system when I shift into second, but will that work? Like will it just come on and start spraying right away after I arm the system going into second? Is the ZEX kit the way to go? I know they say the box tunes according to nitrous pressure and blah blah blah......wtf, Im just getting confused.
BTW, I am SCed and running 12 psi of boost with methanol / water injection also.
definitly will want the 2 step colder considering your SC'd. now as far as Zex's goes........some of the reviews i read even on here on the forum weren't the best. with its whole "module" thing. its been a while since i read about Zex's kits. i went with nitrousexpress/dynotune. but whatever you want man. good start with the wet shot though!
yeah that's definitely something like what your looking for. have you read any reviews on it? i searched a little and couldn't really find much. but alot of people use Zex...its definitely cheaper than the other ones.
well i know mardigrasmax had a turbo with 10 psi and sprayed some nitrous. i'm not sure how much though. his engine was fine...but tranny had problems. you should be fine starting the spray in 2nd gear. but you know how it goes....when you start messing with stuff it starts to break! haha....learned that one too many times

^ thanks for the help man, looks like the maxima community did not venture too much into the world of the bottle, I read the stickies and saw some nice setups.
After alot of reading I am almost ready to do my setup. Just as a little insurance policy, lol. Now all I have to get is about $700 to buy the zex wet kit and the traction controller box and it should be good from there.
its all good bro. i know i didn't tell you much that you already didn't know but i just tell you want i learned along the way with my nitrous.
props on the reading....its always a good insurance policy!! haha. most if the info is always out there it just takes time to find us.
dude keep us posted on your setup and your progress. i'm interested to see how the traction module works out and the SC with nitrous. take some pics and post them! good luck dude!

^ will do Kevin, I have some good rubber on the car now so hopefully the 2nd gear spray will not break them loose. If they do I have some drag radials that I can use.
ah! those are some good tires. i wanted to get some of those but they don't make the size i need....guess i'll get those when i get some 18'' 350z wheels
good luck with the instal man. when you think it will be ready to spray? have you been drag racing before?...i'm guessing yes

yes the tires are great, should be spraying soon, by the end of the month.
dying to get to a track.....just dont have the time man, but seen my fair share of street action

good choice with the zex, its so easy to install, ive had it for about 2-3 months now and loving it, you should look into the racer's kit package as well, its got a purge kit, bottle heater, blown down tube (required for drag racing at most strips), and a bottle pressure gauge. if your going to ship it to your house be careful, they kept mine at the post office till i called zex and they called the post office to let them know it was empty.

good deal....will look into the racer's kit, happy to hear some positive feedback on the ZEX kit.
I was running a zex kit for a while in my 96 maxima. 55 shot felt amazing in it. I liked the zex kit - it was easy to install and wire up - only took like 12 hours. The only other mods I had were an injen air intake so it was easy to drill into and install the nozzle. Supposedly at a 55 shot a 10lb bottle will last 3minutes about. I'm pretty sure you should be stable up to a 75 shot with them if your motor is in good condition. Anyway, I ran a 15 flat without nitrous (a bunch of other mods) and a 14.3 with the 55 shot. I just kept the nitrous switch off til I hit second then flipped it on the way up from shifting to second then gunned it. It worked for about 30k miles and then the motor blew so be careful.
well I have been reserching and gathering information and prepping for the install and blah blah blah.....here's my question. The jets for lets say a 55 shot is calibrated for stock fuel pressures, with boost and the FMU my fuel pressure shoots (high ~85 psi) up when I hit boost......I guess I need a smaller fuel jet or larger Nitrus jet to compensate for this. Or does the zex box have some sort of fuel pressure regulator in there?
Im also a nitrous noob.
my 3.slow has gone through over 50lbs of wet 75 shots.
judging by several nitrous dynos you shouid be concerned with the afr.
Aslo be concerned with the flow rate of your pump.This is why I now have a walboro high psi pump. It would be a great idea to purchase a bigger fuel jet just incase you run lean like
I did. DYNOTUNE FTW. Goodluck

I would suggest getting both a smaller and larger fuel jet and adjust till your a/f is were it needs to be on spray
you should tap the fuel line for the nitrous right after the fuel filter and before the fmu so you are getting a steady psi no matter what rpm your at
and like stated above make sure you have a good pump that can hold psi and you should be fine
I am pretty sure you have one but if not get a a/f gauge or tune at the dyno

^ thanks, I got a wideband and fuel pressure gauge.....I ditched ZEX, their stuff is too expensive. I went to dynotune and will be looking forward to the install and setup as soon as I figure out which coil I fried on the car......
I been reading up on nitrous and it seems like the people that are having problems are the ones that do not do their homework or the ones that over do it.......I feel that I have a pretty good understanding of how it works to have a successful install.
Have you contacted Cmax? He (as you know) has been running N20 and supercharger for a few years now, and he can help you.
I was following you thread, did you get that J and S? It will help you greatly....
I was running the Nx kit on my white max and I loved it. I picked it up for $350 off the .org with everything including heater, purge, racer kit with blow down tube . So look around the .org.
Well, after tuning my car and juicing all the power I could get which was closer to 400 than my 369 dyno the 3.0 finally gave up. By giving up, I mean the motor held but the weakpoint is the head gasket. To overcome this I will be getting into my winter build early this year and beef up another low mileage 3.0 to handle some serious boost and n20. However I am looking into turbo......hopefully will be turbo + n20 by next year.
build should consist of, cometic head gasket, arp headbolts, pathfinder cams, stiffer springs and retainers......then boost the **** out of that ***** and see how well she holds up.
Nice thread, i too am running Nitrous. I've got a Zex dry 55shot...works awesome. No probs what so ever. Got a question...i want to go up to the 75 shot, however wud rather not have to replace or fabricate a whole new fuel rail and injector set up. My dyno-guy suggested possibly re-calibrating the ECU, or getting a chip to produce the appropriate air/fuel mix increase to handle the larger shot. Have any of u out ther tried or done this????? Wud it work? In theory it sounds like it wud.

I ran a zex dry kit and I max'd out the injectors with a 100shot and a walbro pump. I have dyno proof to back it up, I would not suggest going over a 55 shot with stock injectors and pump. And 65shot with stock injectors and a walbro anything beyond a 75 shot you should get either bigger injectors or convert to a wet kit which is what I did and picked up another 38whp

thnx for the info...so u say i cud go up to the 65 shot, but shud get the Walbro pump if i do...got it. Did u have to pull the fuel tank apart? cuz thts were the pump is..sounds like a pain in the @ss!

You do not have to pull the gas tank apart.. The fuel pump is located under the back seat..

sc and nitrous is overkill, just by a ten speed bike and call it a day,lol. theres a few things you must put in place if you want to do this successfully. most of the stuff was mentioned already, but the main thing is be very careful and just dont throw it in and start racing. of course when we meet up i can help you more, good luck. p.s should i bring a stack of 20's to our next kill meeting,lol.
....i wish 
....some of the reviews i read even on here on the forum weren't the best. with its whole "module" thing. its been a while since i read about Zex's kits. i went with nitrousexpress/dynotune. but whatever you want man. good start with the wet shot though!
