Safe Nitrous on a B18B? (stock internals)

Just have a couple of quick questions reguarding nos. Other than an AEM Cold Air Intake and a CatBack Exhaust, my LS engine is stock. No upgraded internals whatsoever. I don't exactly have the money for turbo or LSVTEC, but it would be nice to have a little HP gain, and I heard nos can do so, even at a low shot. Would it be safe to use nos with my stock engine? And can it be done without a tune? I heard with the lowest shot you dont need to tune. Also, after I got my Integra I really started getting into cars, which was recently, so I'm still a noob at all of this. My cousin is on his way to becoming a mechanic, so for any upgrades I've just done it with help from him, learning along the way. Would nos be fairly easy to install? I'm sure my cousin can handle it, I just don't want it to be too tedious.. Sorry for all of the questions, I just really want to fully comprehend all of this.

Thanks.

Yes its safe. Its better on a tune. But 75 wet shot max and 25 dry shot max. Get a Walbro 255lph hp fuel pump and retard the timing 4 degrees. (I think it was 4 degrees). Also get a window switch, or a ZEX kit (comes with a window switch, also has a N2O pressure monitor that will adjust the fuel to bottle pressure, aka ZEX=best)


I never got around to tuning mine (sold it) but it was a 94LS auto all stock power wise (just an icebox intake) fully stock exhaust. Just a walbro 255lph hp fuel pump, NGK Iridium plugs, timing retarded to a sweet spot, and a ZEX wet kit. Ran a 75 wet shot and never had an issue.

you can safely run about a 30 shot of NOS as long as your not using it all the time. but beware... no matter how little the hp gain its still a HUGE risk to your engine

Just as large as a risk a turbo or supercharger. Done right N2O degrades engines at the same rate as the two aforementioned

Is your car an automatic or 5-speed? Either way, Mteg is the man around here to speak to.

I think Mteg runs a lot more than a 30 shot? And I also think his internals are still stock? Too bad I haven't seen him in a while. He probably just browses the forums sees all of these retarded noobs and their stupid ass posts and threads and then leaves.

end mini rant lol.

I really don't have a problem running a 30 shot, for now I just want a little extra power, and to be safe as possible. Later on I'll take it farther. And its a 5spd by the way.

Thanks for all the responses. If I dont get it tuned, does it just not perform as well as it could? And what does tuning actually consist of? (Sorry, noobness acting up)

Lean Fueling will harm your engine while giving nitrous, like the person said above install a Walboro 255 lph fuel pump and a fuel pressure regulator (FPR) just to have an idea what pressure you are running your fuel. and yes never run it on Advance timing or else you end up on broken pistons.

And as for your last question nitrous is a simple power gain, if you install it right. and Tuning of Nitrous is Easy you just have to Watch for Proper fueling in my opinion, I tune with the help of Wideband if i have to tune a car on heavy nitrous If you know what i mean.

and a another thing Greed for HP is a Bad thing. so Dont go running 75 shots jet.

A FPR is a good plus to have, you can bump the pressure a bit. Nitrous isnt as bad as the ricers who blow motors on it claim it to be. Tuning can be anything from a kpro/hondata to something as simple as borrowing someones wideband getting a fpr and have someone who knows what there doing play with that and timing. Obviously if you go to a nicer unit like hondata your results will usually be better.

Also I wanted to comment again that a 75 shot is fine. But it MUST be wet (aka fuel and n2o is put in). Again i'll preach the Zex unit, the wet unit will automatically add extra fuel given the amount of n2o being put in (monitors bottle pressure so even as your shot changes from full to empty tank, it is calculating for that). So that Zex unit plus a walbro 255lph hp(high pressure version), a retarding of the timing about 4 degrees, some better plugs, and a fuel pressure regulator (optional but highly recommended for fine tuning) and a 75 shot is fine.

Its sure is safe to Run 75 shots, but for the first time its mad.

Thanks for all the responses guys, really cleared alot up. Another question though, if I tune for nitrous, then what about when my tank runs out, or I'm not using it...won't everything be off becuase it's set for the nitrous? Sorry if this is a noob question, just I've never had to "tune" for anything before.

Not really. A nitrous motor is setup similarly to a turbo motor, just no boost. So your car will be slow as fuck, but nothing else will change without the juice.

'Tuning' is altering the air/fuel mixture and timing (among many other things) to keep a motor from detonating. That's a very simple explanation, but a motor is 'tuned' to run safely with mods at it's maximum. Not sure if that makes sense; I'll try to clear it up if it doesn't.

Yeah, that does make sense. I get it. But you said my car would be slow, as in when I'm not using the nos? So wouldnt I have to tune it everytime I plan on driving without the nos if I want to be a decent speed? Sorry, just a little confused on that.

See following for no tune, now for after tuning see the bottom comment

Depends on the tuning software you buy, but your best bet would get a system that lets you switch maps on the fly. The tuner can set it up so that N2O engaged the ECU will switch to your N2O map on its own, then once the N2O is off it will revert to stock map.

That makes sense, being able to switch when its off and on. But won't that be expensive? I'm still in high school, and nitrous itself is gunna cost me abit. What did you mean by "see following for no tune"? Does the Zex kit not require tuning? Sorry about all the questions...

Because of how the Zex kit works it is just about the only one thats mostly safe w/o a tune. I never got around to tuning mine, and with the aforementioned stuff to get I was fine. I went through a good 15-20 bottles on a 75 wet shot. :lol:
