Cool NE1 thought about getting a NOS?

I am seeing if anyone knows what I can expect from a 50-60hp jump from a NOS kit. I have one on the way and I am real excited about it.

Talked to NOS and they said that this system would work quite nice with the car.

I wouldn't use it a lot. Just when I first got it. I can't spend the money to keep getting the bottle filled anyways. Plus its just a 50-60hp boost. its the smallest that NOS sells. I think I will be fine. Its built for stock engines too.

ummmm, does it compensate for fuel?
or are you going to add fuel somehow?
if not then with a large amount (to get 50-60hp) you can definitely expect a nice "boom" (or something to that affect)
the best kit I have seen is the Venom that taps into your fuel system and makes sure to add the correct amount of fuel to have everything in your engine nice and happy
It also has a safety feature in where it cuts n20 when it senses a lean condition
email me and I can hook you up with someone who can get them...

Well, you do need to somehow make sure you add extra fuel when the nitrous kicks in, and also a rich/lean gauge will help, so at least you know what exactly happens when the nitrous is on.

Well whats suppost to happen is this system will cause the Mass air Sensor to pick up the difference in O2 causing it to inject more fuel which means more power. It suppost to be a system set up for stock engines. This is what a NOS Tech at NOS told me so I think its all good. They said that I shouldn't see any problems. If I heard anything weird to call them and they will tell me whats wrong. Hopfully they know there stuff about the Scooby.

getting a shot is ok if the car is just a race car but remember.....you have to use the best gas...and you have to retard the timing 2 secinds for every 50 shot...all the time just so that one time you want to use the juice it will work right..thats too much bull**** for me but if i did get a kit i would get the VENOM kit, everything is computer controled, all you have to do is turn it on

Uh oh! The tech told you wrong. The kit that fits your car is kit# 5123, not #5122. Kit# 5122 is for my car (2.2ltr). Maybe they made changed after I got my kit but that's what my Nos manual stated. Again, kit#5123 is for your car, dry manifold that is.

BTW: Don't use your Nos for more than 15 second or on the highways.
Try to avoid using it below 3000rpm.
Experiment with the lowest jetting first.

I've been using Nos for 2 years with my turbo setup and my engine DID NOT go boom. Actually I used the highest jetting for my kit (70 shot) on my last bottle I had filled. It was a huge mistake since I put that jetting in by mistake. I thought something was wrong since my bottle emptied out so quickly. You can imagine how my heart felt when I looked at the jetting size when I changed it back to its smallest size.

At any rate, good luck! And by all means get a bottle warmer if you can help it. It'll increase your bottle pressure from 500-600psi to 900-1000psi. Lots of extra power that'll shove you back in your seat. Get it if you can. L8Rs

its the small 4cyl version that NOS makes that gives a stock engine 50-60 hp. This is what the NOS Tech said.

The kit that should fit your car is part number 05122 and will add 50-60HP safely to naturally aspirated, multi port electronically fuel injected engines.
This kit is also easy to install (about the same as a car stereo install w/amp/CD changer 3-5 hours). No other mods. are required to run this kit. This kit is a "pressure boost" style of dry manifold nitrous kit.


Thanks, NOS Tech Dept.

How much does it cost to get a 10 or 15 lbs bottle NOS filled?

I could be way off base with this, and if I am let me know.

I didn't think that the MY2000 Imprezas used the Mass Air-flow system any more. That's why the newer cars don't have the problem with adding an intake. If your kit is relying on the Mass Air sensor to kick in the added fuel...you might have a problem.

As for nos in general, you can use it safely as long as the extra fuel is there. Electronic cut-offs with a gauge are the best choice.

Again, if this is wrong, someone let me know.

well having the smaller system probably won't hurt it would it.

Its $3 per pound here in louisville. Also I thought the MY00 still had the MAS but it was moved by the throttle body. I was looking at it and looks as if it was moved.

Well then I am sure the MAP will sense the additional O2 from the nitrous wouldn't it??

MY00 & MY01 use MAP sensor rather than MAF.

Be careful with nitrous. It's illegal in many states to transport it without the appropriate "placards" on your car. Chances are that you'd never get caught, but if you do . . . the fines alone can really suck. Just a friendly warning

One word if your want added fuel when u hit the nitrous ZEX. I have the kit and i recently just ran the 75 shot at the track on sunday and it the car ran fine. Ive used the kit for about 2 bottles at 55 and then one bottle at 75. And as Kevin said get a bottle warmer they make a night and day difference. Oh and regarding the timing, I talked to the Subura mechanics once i couldnt find the distributor to retard the timing, and they said MY99 have a stock knock sensor and electronic timing control so if the sensor hears a ping it retards the timing on its own...

Narso,

Do you mind telling me what states say you need a placard on your car to transport Nitrous?

A policeman told me this before and we got into it. He was telling me that if he caught me with my bottle in my trunk in Maryland that he would throw me in jail for not having a placard on my car. Since I travel to Maryland to attend events at Maryland International Raceway, I checked into it. I was told by 3 different agencies (I can't remember their names. It's been awhile) that dealt with toxic chemicals and transporting them and they all came to the same conclusion. That a placard was not needed unless I was transporting X amount of Nitrous. 1 or even two bottle of Nitrous did not fit the requirement of having a placard on your car. You just couldn't have the bottle hooked up and armed while you were going to an event or anywhere else. I'd check with your local OSHA, DNREC and a few other agencies to be sure but I'm almost positive this will be the case.

At any rate, I gave all the info to this policeman about who I talked to, when, where and what time and challenged him on this since I was attending an upcoming event at Maryland International Raceway and he backed off. Guess I called his bluff or he just really didn't know what his state law was. At any rate, check into it just to be sure and even call the local police in that area to see how they would handle it.

Everyone has their own opinion about nitrous ... it's like getting a turbo in a way. You need to understand all the pro's and con's of installing a massive power adder to your otherwise stock motor. It can potentially damage things if you don't take the proper precautions.

1) Have it professionally installed by someone who knows their stuff with nitrous oxide.
2) Don't abuse it ... it's hard not to, but don't.
3) Don't spray in 1st gear unless you REALLY know what you're doing. 1st gear is too short and you'll almost always hit the rev limiter.
4) Don't spray for more than 15-16 seconds a t a time.
Edit:
5) Run one step cooler plugs - DO NOT USE PLATINUM PLUGS!
6) Retard your timing by 1 degree.

Nitrous oxide will cause premature wear on your stock internals, but so will a turbo. If you run any more than a 50-60HP shot, you'll need up upgrade the fuel system to provide more gas, so you don't run lean. I'd recommend a wet setup for more than 60HP on an Impreza.

You should also concider upgrading your fuel pump as well when installing the kit, added safety. More fuel is always good when spraying or boosting.

I'm currently selling the 5125 kit from NOS here , which is a big honda kit (I ran it on my Ford Probe at a 70 shot). It will provide 50-70HP to your car. The kit you have is the same exact thing, just smaller jets.

I highly recommend reading up on what nitrous oxide really is and what it really does in your combustion chamber before you install it.

I'll have my kit installed in a few weeks, so I'll let you know how it turns out. I'm going to run a 50HP jet for now and see where my Air/Fuel ratio sits. If I can go to 60HP, I most likely will.
