I have exatly 65,000 on my car and am currently installing a ZEX kit on it. I havnt sprayed it yet because I want a few things in place before I do. I bought a range colder NGK plugs for part# 6097. I also want to install an EGT guage (already installed AF meter)

Also some people have trouble with the clutch holding a 55 shot. I think our engine can handle it fine, just not the clutch. for this reason I am going to retrofit a NOS jet to the nozzel so I can run a smaller shot. prolly a 35 or 40. I dont forsee any problems with this setup, but im kind of anal....I want to be safe.

I should have it finished within a week or 2, then I can update you on how it goes.

wow what a useless post...not only are u completely unhelpful you are wrong

"of aspirare to breathe toward or upon, to add the breathing"

refering to pressurizing the engine...nitrous does not increase pressure!

ok, I definatly am not wrong, nos is forced induction. it's not hard to figure out, N/A means that you don't have a turbo, supercharger, or nitrous. you can learn that just by going to a track or picking up a book.

maybe thats the definition from a car enthusiast's perspective, but from an engineering perspective id say nitrous can stay in n/a, pressure is increasing ever so slightly

but more importantly ur post was a completly unhelpful, if he posted in the wrong place maybe instead of saying "wrong place" you could have linked him to some relevant information!

no one ever said if you post it has to be helpful. there is a nitrous section, it's called forced induction. that's where this post belongs. and yes everyone would agree with me nitrous does not keep your car naturally asperated it dosn't matter what your definition is. look at it my way, say you're looking in the sti sectionand people are posting pictures of their car and asking what kind of exhaust they should put on their car. then other people in the same section posting about their sound system all in the sti section. just keeping control, don't want stuff to get out of hand.
mods please move this thread to where it belongs.

Running a 55 shot of nitrous on the RS motor will not cause too much harm, at least in the short run. The motor should be fine, your clutch, unless you have previously upgraded it, will go pretty quick. I have heard that anything above 55 is going to start putting significant stress on the motor and all drivetrain components. Colder plugs are a must as well.

As far as this threads location though, I agree with Supraru

Good luck with your setup, what kind are you getting by the way?

Well, nitrous is not forced induction, you're still under vacuum, not boost (Unless you have nitrous on a FI car). You're merely providing a cooler, more dense intake charge. I'm sure driving in Antarctica would have the same effect

it is still n/a...
the motor still has to "SUCK" the air in it ain't being forced in.
all that is happening is a power adder is being injected into the air and that combo is being "SUCKED" into the engine

Just keeping control? That's funny, I don't see a moderator title. Nitrous posts about 2.5L n/a engines belong here. Now go away troll.

he is whats refered to as a "Troll"

It definately belongs in the NA catagory.....but I think there should be a dedicated Nitrous thread...I searched for hours on end getting info on it and digging through all of the repeat posts. Would have been nice to have it all in one place. Just my opinion....I dont have "control" or anything...

Definatly not a troll you guys crack me up. Well lets see you go to a local track of your choice and enter in a competition running nitrous and see if they put you in an N/A class. They won't. They will put you with the turbo charged and supercharged cars. You may be right about it not being forced induction but it dosn't fall under natrally asperated.

Yes, you are correct that nitrous will put you in a different class. That's not really the point though. The point is all of the people posting about nitrous in this forum are talking/asking about nitrous on a N/A car. If they were posting about putting a kit on a WRX, it would go in the FFI forum, an RS-T or supercharged RS it would go in the AFI forum. So you see it would be pretty stupid to post this in either of the forced induction forums and there is no nitrous forum. Maybe you should ask Nick to create a nitrous forum so you can sleep better at night knowing that every post is in it's exact place. I'm sure he has nothing better to do than re-format NASIOC's forums for you.

Sheesh. N20 = NA or FI? I've seen it posted both ways and try not to get worked up over it. Anyway, my young 2.5 seems to run just fine on a 55 or less shot of nitrous. I haven't tried anything higher. However, my theory is that any extra hp is extra stress = shorter life. How much less is somehow proportional to the extra stress. An engine weak link is probably headgasket. Play = Pay. At a 55 shot of ZEX, my clutch started slipping briefly after about a dozen 3 second blasts. It does lock up eventually. I think a progressive kit might help avoid the sudden "rush" that seems to cause the slip. Course, I kind of like the rush.

i wish ignorant people like you would learn when to shuit the hell up, you obviously have no idea what your talking about.
just because its a power adder dosent mean its forced induction, somehow you are confusing the 2 categorys.
and if you go to a racetrack they wont put you in a turbocharged or supercharged category, they will put you in a power adder class, for forced induction and nitrous. your a moron

now as for nitrous, i have neve had it on my subie cause its too slow. but i had it on my contours, a 98 svt contour with a zex 75 shot, and a 95 se with a manual solenoid activated dry 85 shot, i had a safc for fuel control and i richened the **** out of it when i ran it.
engine wise, as long as your not going for etended shots should be find on a 55 shot, anything higher than that will cause premature engine wear.
