the thought of adding a nitrous system has recently entered my mind.. hehehe.. i have a 95 gle with about 70k miles on it. my questions are.. how big of a shot can i SAFELY run? if any at all that is. what kits are made for our cars? can i use one of the zex systems? what else should i change (fuel pump,ignition)?what systems are you nos max's using? for how long? any probelms? is this a stupid thought? how much do the kits u guys use go for? im gettin the bug so now i need to look into it.. i think i just wanna be able to put some small NOS stickers in my back windows and put a purge system in it just so i have a new toy. hehe please let me know

 

Do a compression test before nitrous. The following links should answer most questions. I believe the NOS kit is still available through jcwhitney.com for $375...

Why do you want to do this? You'll probably blow up your car and then blame Zex

 

 

without an upgraded fuel pump, you could do about a 60shot at most - safely. NOS seems to be the most popular choice among max owners. a ZEX kit will work. i've had my kit for about a year and a half without problems.

 

haha.. nah.. then ill just be on the prowl for parts.. hi.. where do u live?

 

what zex kit are u running? i already looked at their application chart and there no listing for a maxima. mind if i asked how much u paid for it? are you running the remote bottle opener or the purge kit from them either? is that what u have it set for, 60 shot i mean? oh. how many miles are on your car? thanks..

 

i don't have a ZEX kit. i have an NOS kit, but i know someone that had a ZEX kit on a maxima. it cost him around $400 for the ZEX kit. it's a universal kit by the way, they don't make one specifically for the maxima. i have a purge kit from NOS, i'm running a 100shot, and i have 40k miles.

 

i coulda swore when i was on the zex site they had an application chart with diffent models pertaining to the cars.. or mabye its some kinda software. i duuno.. did you upgrade anything for the 100 shot? i didnt think id be able to use a shot that big safely.

 

A 100 shot of NOS requires a new fuel pump, gauges to moniter fuel pressure, air fuel ratio, and exhaust gas temp or recommended, you will need a step colder plugs, along with a reduced gap, and a lot of tuning. Start small, around a 50 shot, and work your way up from there. Good luck. Patience is the key to safe NOS use

 

So it seems to "possibily" run 100 shot on a mechanically sound engine all you need a upgraded fuel pump, FPR, and colder plugs all others are to keep a eye on vitals.

 

Hey...Everyone is talking about adding nitrous oxide and all...Doesnt it ruin your engine ????? Regardless of how much you add ? I've heard even adding small amounts slowly ruins your engine...its just a matter of how much or little you add...faster ruining...slower.....isn't this true ?????

 

No...

 

Wow. Seriously ? Hmm...

 

When I was installing my NOS kit at my local Hobby shop, one of the on site mechanics kept coming by and saying "Your gonna blow your engine!" I finally asked him why he thought I would blow my engine, his response? "I put a 150 shot of NOS in my 92 Ford Probe, the first time I ran it, it blew the engine!" My response? "Well duh, you stupid a$$ dumb $hit!"
IMHO, NOS is comparable to a turbo or a supercharger. All add power, but when that power is abused, bye bye motor. Any aftermarket part is potenially causing more wear and tear on your engine. If you are adding aftermarket parts, you are most likely driving your car harder, which puts more wear and tear on it. In a nutshell, NOS add's oxygen, and cools your intake charge, increasing the power of your engine. It doesn't stuff the air in there like a supercharger or Turbo, it just provides it in a nice mist. Don't add enough fuel to go along with that, and you get detonating, which causes engine damage. The increased pressure will put more wear on your internalls, but it's not like your running it all the time, like forced induction. Then again, there is alway's the great quote which will always hold true... "Ya gotta pay to play". Play smart however, and you don't have to pay as much... Just my $.02

 

by the way.. what sorta tunning do you mean? im assuming i'd have to retard the timing 2 degrees if i wanted to run a 100 shot.. but what else? and i gotta ask this.. what kinda cars have you raced and beaten?

 

By tuning I mean the following; Frequently check your plugs for detonation and signs of leaness, this is a must no matter what shot you are running. With a stock max, you should be able to, fuel pump good and all, run a 60 shot with no other mods. But once you add an intake, exhaust, etc, you start to run into fuel problems. The stock fuel system cannot supply enough psi to deal with all the extra power, which is why you need to upgrade your fuel pump to go above a 60 shot safely. I tried a 60 shot with my current mods, and I was running lean, so I went back to the 50, but hopefully my new fuel pump will be here this week. When you start getting to the higher HP's like a 80 or 100 shot, it is also a good idea to get on a Dyno with a broadband a/f ratio meter and find out exactly what your running, lean, rich, etc, so you can get the most HP out of your car and still be safe. Patience and Safety cannot be stressed enough. Rushing or getting greedy on the power will only equal bad things. If you haven't already, check out http://www.clubmaxima.com/articles/N...ForParties.php by MardigrasMax. Great article and very informative. Good luck. BTW, for the last question, I don't use NOS on the street, but if I ever did, Mustangs, Camero's, Honda's, Acuras, Lexus's, Toyota's, Etc, all depends on the car AND driver...

 

i hate to keep pestering you with questions, but you seem very educated on the matter.. i have a 95 gle, automatic. im currently waiting for a stillen y pipe, stillen b-pipe, random tech. cat, and already have the stillen ss muffler. i was planning on getting a CAI also. if i do decide to juice the car, it will most likely be a few months down the road. this is why i started asking questions now so i can give myself some time to learn exactly what i NEED to do. im sure id be happy with just a 60 shot, but i was kinda leaning more towards like 75. the zex kit has caught my eye and if i can, may decide to go with that. mind if i ask what kinda of fuel pump you bought and how much it ran you? im going to the local speed shop in the next few days to talk to the owner about his thoughts on what i should do. im a long time customer there, and do trust his word, but would rather walk in knowing as much as i can before hand. any other advice for me?

 

Well a 75 shot WILL require a new fuel pump. I ordered a 255lph Walborro pump, which I was recommended by the other NOS users on this forum (thanx). It set me back $118 shipped. I think the part# is FPD006, but it's the same high flow 255lph pump that they sell for the Eclipse. http://AutoPerformanceEngineering.com
is where I ordered from. I have the Nitrous Oxide NOS kit, and I don't have any experience with the ZEX kit, so i can't really say anything about it good or bad. Good luck.

 

thanks for all your help.. i checked out that site. very informative.. thanks again
