Default NOS?? Good or Bad on '00 RS??

My friend amzingly is able to hook me up with a free used NOS kit from a shop he knows and just got alot of work done at, the nos kit was originally used by a dumbass who blew his engine ( not sure what car ) and he is now giving it away. It is a 100 shot nos but to be on the safe side i would get a 50 shot nozzle because i have heard bad thing, Im just wondering if this is a good idea to install on my 2000 2.5 RS with the only engine upgrade being an AEM short ram intake, also do I need other modifications to have it work? Any recomendations on what i should do, after all, it is free...

i heard that every time you use nitrous you take 1000 miles off your engines lifespan. that is, assuming you dont blow your engine when you use it

That is utter BS.



It'd be helpfull to know what it came off of.


I wouldn't worry about a 50 shot ruining your engine. As long as it is not used excessively.

RSblood, the RS is not the ideal setup but then again people stick nitrous on anything. From what I've read nitrous can be safe on just about anything too, if properly installed and safely used. I believe it's illegal to use on the street too... It's really a ricers wet dream in that it's only made to go fast for a short time (light to light), is relatively inexpensive, and can bling out anything even if with a microscopic shot of juice. Now since it's free...just be careful!

I don't think I've ever seen you say something remotely factual in General.

Just leave the NOS to the ricers. You're subie really doesn't need it. Find other ways to get more power into your car that are safer and won't hurt an otherwise reliable car.

It's your car. Personally, I wouldn't bother. I had a friend with an 01 RS that got a kit and everything and it sat in his room for like a year. He didn't want to bother with it either.

I'm always amazed at how people react or respond to nitrous questions. Just because you don't know anything about it doesn't make it "a ricers wet dream" or a bad thing.

As with any modification to improve a vehicles performance you have to look at it realistly otherwise you will be disapointed with the results. If you are thinking that you can install a 200 shot with no other upgrades and run 9's all day long. You will be dissapointed and end up with a blown motor just as installing an over sized turbo running maximum boost will end with the same results.

If you want to install nitrous be cautious, do your research, and mod slowly. Taking your time to do it right can result in a dramatic increase in performance with limited harm to your motor, self, or pedestrians.

To answer your specific question: I would look to upgrading the stock RS exhaust system (header + Cat Back). Make sure you run the appropriate spark plugs (for a 50 shot one step cooler will be sufficient). Make sure to get guages (bottle pressure, fuel pressure, ect). Engine management sould not be required unless you get a specific tune for nitrous (most EM advances timeing but when running nitrous you need to retard timing).

Good luck and like I said above, take your time and you will enjoy.

I commend you on some of the most well thought out responses to a question I have heard in a long time on this board. This is the type of response that got me interested in theis board in the first place.

Bottle warmer and bottle cover definitely improves consistency in using the nitrous setup. A small shot like a 50 is no big deal, you could probably even get away with a 75 jet but without full exhaust I wouldn't push it. A 50 shot can generally be used safely on most bone-stock cars, but your safety margin definitely goes up with a set of headers and a nice cat-back.

there are many that have done it on the boards. I believe Kevin Thomas has nitrous on his RS but i may be incorrect.

Is it a wet or Dry kit. From the research i have done wet is safer.
I personally wouldnt feel comfortable with nitrous unless i had lots of supporting mods. wet kit, A/f guage,egt guage, knock link, a method for datalogging, method for adjusting timing and fuel.

if you plan on using it, just be careful you don't end up being like the dumbass who blew his engine as stated above.... personally i say screw the Nitrous, but thats IMHO.

Boost is rougher on an RS than an equivalent shot of nitrous...

Do it.

Nitrous is fine I ran 13 bottles of a 75 wet shot on my last block with already 112k on it and it finally blew a hole in the piston. Cheapest mod with greatest horsepower just look at my dyno sheets with it. http://rallitekforums.com/forums/sho...0&page=2&pp=10

Little bit of a wobbly torque curve but very nice gains. What sort of supporting mods did you have to pull 160 whp out of it before the nitrous?

id put nos in my car is a second, but i'd probably just show of with it, pull up to a stop light with a civic there and just shoot the nitrous purge a couple times to make them feel like sheet

very nice numbers. I'm going to run a 100 shot in the near future and see what that gets me. I'm going to have all bolt on, cams, and the nitrous. I'm sure with a 100 shot the numbers will be even more crazy.

Simple supporting mods can benefit alot. Open up the engine and let it breath and you will gain even more with the nitrous. Add an svx fpr and wrx fuel pump and you should be able to run a 35-50 shot all day long. Now your clutch... that's a totally different story.

Exclamation good luck

I hope you have some way of adjusting ignition timing. RS tend to run kinda advance tuning and that much N2O will be hard to tune safely without detonation and melted pistons. Even though N2O isn't always on, 100hp is still 100hp and will create similar cylinder pressures, putting alot of stress on the rotating parts(bearings, pistons, etc) Setting up a car to run really good with N2O usually follows in the same path as modding it for an aftermarket turbo kit, and can be equally expensive when you start to run alot of N2O.
