so many threads!!!! well after searching it is really unclear....what suggestions do you guys have for the best kit option for the 2.2 balts? i heard some kits like NX i think come w/ window switches and whatnot....i am not tryin to spend endless loot but dont want something cheap that will fuck up the ride....let the comments begin!

any of the major brands, NX, NOS, ZEX will work just fine. they all have the same basic components so you won't see much difference between them.

good to know....ya slowion2 told me to that route as well. I just need to make sure it is installed correctly...thats the main thing right? And how hard are they to install?...im no tech but i know my way around a car and a garage...think i can do it...did my intake and exhaust but those are way too easy

i knda feel stupid askin all the ?'s but i have never dealt w/ n2o...i also asked slowion what other parts are needed...i want a purge kit but i can only afford the absolutly necessary parts...like a heater cuz it gets cold soon...what else should i get other than a heater kit?

i know it has only been an hour but im ordering asap...so....bump

damn another 2 hours....bum bump....no more bumps untill tomorow...plz respond guys lol im dyin to spray!!

well i'm going with the Zex kit, its got the cleanest install of the mainstream kits. the only downside is the pinkness.

i'm sure if you can do a little bit of wiring it shouldn't be too bad...

a guy out here by the name of Fatalis has the NX kit on his Ion sedan and he says the install wasn't too bad at all. and it was his first time with nitrous too so I imagine its not too hard.

as far as bare minimums of what you need.

wet nitrous kit
msd digital rpm window switch (although I believe you have an auto so not sure how important that is to you)
2 step colder plugs gapped at .035(NGK BKR7E-11)
91/93 octane ;)

if I had to get the bare bare minimums, which I am that is what I would get. I would then get the accessories kit later on which usually comes with the bottle warmer, nitrous gauge, purge, and blowdown tube. its cheaper to buy it in that kit than individually...

but if I had to pick one from that list I'd go with the bottle warmer...

You shouldn't need a bottle warmer unless you are trying to achieve a specific bottle pressure on an unregulated system. Since you are probably only using a small shot, like around 75, a higher bottle pressure won't do anything for you.

Yo.

Install is pretty easy if you do enough planning. Wiring was the easiest part and I did it correct the first time. Yea, sorry to say that nothing was reallly that hard and you dont need a shop to do it.

I pretty much have the bare minimum on my kit with a purge.

NX GM EFI wet kit 10lb bottle.
2step colder NGK 7e-11's (Colder plugs)
MSD Digital Window swith (some will argue that its not necessary, but I believe it is)
NX Purge kit

Thats pretty much my kit.

I dont have a heater but I live in AZ so the heat does the job for me. STill my bottle pressure is going to be low, but my shot is still healthy enough to feel the power. A heater will do wonders for the shot though. 950psi is a hell of a lot different than a low 800psi. Or so im told.

You may also ask why ive had so much succes and not even a slight misfire on my car. its becuase of hours of research and the badgering of SlowIon2.

The only real problem i had, was my spark plugs. But i think after like 50 nitrous runs they fouled up, so you have to switch them out... always keep a couple sets handy as well. And check the plugs a bunch to see if youre running lean or rich.

As for kits: NX, NOS, Zex, Nytrex are the main ones ive heard of. Personally ive had success with NX, but the others are outstanding kits as well. Zex is more user friendly.

thanx guys....lol ive been badgering slowion as well...he knows his $hit....i think i know what i need now so i should be good to go...gonna self install too woot should be fun:lol:

just wondering if you get the colder plugs would i have to change them out for daily driving or would they work ok

okay, so ive really only been INTO cars for a few months now, and know plenty on the cobalt...but nos is the one thing i never really looked into...
anyone want a breakdown of how it works?

NOS is a company first of all... just call it "nitrous"

Nitrous Oxide (N2O) - is sprayed through your intake into your engine... the N2O particles seperate and the nitrous escapes the engine, leaving pure oxygen - sinc engines run off of oxygen, the N2O setup provides a PURE set up of Oxygen, resulting in better performance.

so instead of burning fuel in 20% oxygen in the air, its burning in 100% oxygen ...bigger flame....i heard too that when nitrogen separates from oxygen, it absorbs heat energy, helping to cool your engine

if the gas burns bigger....wouldnt that = more pressure n then you'd need stronger pistons?

The intake charge is cooler because nitrous is at like -140 degrees F. Thats more horsepower right there alone.

ALso, you dont need new pistons unless the torque is too much for the rods to handle. The stock rods on the ecotec 2.2 go out at like 250+ hp/torque or something.

So, lets say my car, about 125-130 WHP, add in a 50 shot = 175 whp. Which as you can tell merits no use of stronger rods.

You can run a 75 shot on the ecotec and be fine. 50 shot all day long. 75 shot more conservatively.

I was thinking of buying the NOS Wet Kit from Cobalt-Addiction. They seem to have the best price for Wet Kits. Is the NOS Kit you think just as user friendly as the NX or Zex kit? Its 499 + 30 shipping + 100(RPM Switch) is ~ 650 total. Thats about the price of a Zex kit alone. Plus i like the NOS bottle over the NX bottle =P

I doubt you will be able to tell much difference between NOS and NX kits, to my knowledge they are setup pretty much the same.

The Zex kit is the only one that differs in its setup...

My only concern now is installing the rpm switch. Do most of you guys install them in sight or out of sight. They come with wiring directions right? I know im not going to have a problem running the lines and doing all the under the hood work, just installing the WOT switch and RPM switch. On the 2.2's, WOT has to be under the peddle right?

TNT is IMO one of the best Nitrous companies you can get ahold of. Thier kits for EFI cars are some of the best looking and performing kits I have ever seen. That and their shot numbers are WHP, with a 50 shot you put 50 to the GROUND. UNliek with companies liek NOS and Venom which claim that kind of power. TNTs jets are actually sized with drivetrain loss in mind, so their 75 is more like a 85. It might be a bit much for you but the kits are worth looking into, especially if you want them to make a kit for the cobalts. Hell they might even make it custom for you with no additional cost just cause, hell you can't beat sponsorship.

yes the WOT switch has to be installed under the pedal

which is one reason why I want the TPS switch, the WOT switch under the peddle sounds ghetto rigged

well i thought you would run the WOT and TPS together. For example, you must be WOT and between say 3k and 6k rpms to boost. So you dont HAVE to be in WOT to boost, thats just one way of activating it right? That makes the setup seem a lot easier if you dont have to put in the WOT switch as well. Any good ideas on TPS locations?

I just realized, if you dont have the WOT switch, your gonna boost in 1st n 2nd right? Thought that was a bad idea.

you ONLY want to spray while at WOT, hence the microswitch and tps voltage sensor switch. if for whatever reason you didn't, you can lean out and also risk detonation.

I use the kit in every gear. I'll repeat that, every gear. If you can hook up somewhat, you'll benefit over being off the bottle.

lol @ Fatalis, conservatively? I think I used the 75's more often and such than the 50's, but by then I had a lot more experience and knowledge. hell I had more at 50 than I originally thought.

I don't care where you live, bottle pressure is key. if you want consistent delivery and times, you need to regulate bottle temp with a warmer. I used at first a heating pad and power inverter, which worked but took a very long time. the N.O.S. warmer I have now is way better and worth the money.

you know, not many people mention TNT, and I have heard nothing but good things about their setups. sure they're a little more pricey, but they seem to be of great quality.

exactly. under compression, the oxygen atoms lose their bonds and burn with the extra fuel added. you net a cooler egt too typically when setup right.

just wondering if you get the colder plugs would i have to change them out for daily driving or would they work ok

no, you don't change them out for daily driving, they work fine. they actually last quite a while too, I'm on the same set for I want to say almost 8 months? I may change them out for peace of mind, but they have lasted great so far with no fouling and MANY runs on them.

I would mount yours where you have easy access to it from the driver's seat, but that's just personal preference. to me, I'd rather have control over my arm/disarm points with little effort, and I get to make sure the tach signal is correct when it's in view (mine is hidden but easily exposed, I think Fatalis has it like this too). I also had an issue with losing my tach signal and only realized it by watching the unit itself. I temp fixed it but I will be splicing in a lead to snag the signal soon.

Simmons - did you just call me again today? I've been slammed at the office and all week in general with nationals this weekend, don't think I'm trying to avoid you I'm just up to my elbows in work lol

you definitely want at least the pressure gauge first to see where your residual pressure is at. you can always heat the bottle in a tub of hot water as a last resort, but you don't want to go too high on pressure and risk leaning out a bit.

well i thought you would run the WOT and TPS together. For example, you must be WOT and between say 3k and 6k rpms to boost. So you dont HAVE to be in WOT to boost, thats just one way of activating it right? That makes the setup seem a lot easier if you dont have to put in the WOT switch as well. Any good ideas on TPS locations?

the TPS sensor is just like a WOT switch only electronic, its spliced into your TPS sensor

the WOT switch is mechanical and is mounted under your pedal or on your TB if you don't have electronic throttle like we do.

essentially they are the same thing just a different way of working, atleast thats how I see it.

So with the ZEX kit that only active at WOT would you still need the MSD-OWS or would the ZEX kit be all you need? My lil bro's friend is selling his kit off his GrandAm and I can pick it up for $300. Definately would help my 4ton HHR down the 1/4....

I would still recommend the window switch as well

What about the supercharger doesn't it put quite a lot of stress on it if your running nitrous?

this is a very informing thread. thanks to the the key guys for chiming in and hitting key points.

I am not a nitrous fan due to risk but every time i read an educated nitrous post i begin to want it more and more.

IMO dont use nitrous until you have internals built, not a good idea..... go with performance parts for the motor, dont use nitrous until your motor is built......be smart, about it......

You can run nitrous all day on a stock motor. Ive done, it SLowION has done it, and so has a ton of other people.

All built internals will do is allow you to run higher shots meaning higher power/torque. Detonation can still rip apart forged stuff if it happens, and melt pistons.

I agree with the performance aspect though, you should have basic breathing modifications done before you spray. Spraying nitrous on a stock exhaust isnt that great of an idea. Youll net more power on better breather parts.

I had a tutorial for nitrous on the 2.2(maybe 2.4) in the works, but i abandoned it a while back because I didnt see much interest. But I may finish it since ive seen a ton more nitrous threads pop up.

if you're smart about it you don't need to build anything up...

all it takes is a proper setup and you're on your way...same deal with any type of power adder.

you can add motor modifications and spend alot of money not going anywhere...or you can go turbo/supercharger/nitrous...1 of those 3 things are the only thing that will turn you into a quick car.
