Reply With QuoteYeah it's all about the wet kit. You can use a dry kit as long as you don't go nuts 45 50 shot i've heard of people using dry, but like i said i've HEARD, never really seen.
So after all the threads best to go with is WET NX or NOS with Direct Port? if i am running a 50 shot will it hurt my motor at all stock 02 civic Si with 8700 miles. let me know please im really considering this.

Damage
Will a small shot say 50-70 do harm to my motor at all?? some people say it actuall cleans ur motor some others say it weakens it. i want my car to last me some time, i just bought it.
Dude you can use a WET kit for up to a 75. I suggest using a direct port on the 75 and up for safety. Think about it a wet system n20 and fuel fills the intake manifold. Its pulled in unevenly because the intake is made for air not fuel, Ever notice how on old carberated car the ports on the intake are equal legnth? Thats why because they are designed for fuel too. Direct port is sprayed in by the valve like an injector that way the nitrous is pulled in evenly by the cylinders and lots less explosives fill the intake manifold reducing the risk of fireworks in case of an intake backfire. I doubt that n20 cleans the engine in any way. Any hp adder will cause a reduction in longevity with the exeption of stuff like i/h/e as these (adders) are just freeing up power that is already being made.
ok, if you have any questions about anything you read on c-rsx, ask it over there ;)
But hopefully, i can help out a little over here too.
You need a wet kit. Nx + Nos are basically the same kit. You do need a WOT switch, as it is only safe to spray at wot.
125 has been done on stock plugs, stock internals, no issues. However, no one said it'd last forever. With using it every so often, you won't experience much extra wear at all from a 50 - 75 shot (wet). A big concern with nitrous is heat. When you pour all that extra gas in there, and run it, things get hot. This is why there is a 15 second limit on spraying (rule of thumb). Anything more, and you're quite possibly gonna start melting internals.
As far as cleaning? well, you're putting more gas + more air into the engine, so yes, it's gonna burn hotter, and hotter = cleaner.
Direct port is not needed for anything 100 or below. 125 is even fine with a single wet fogger. However, some people crave the DP setup, and while it is "safer" when properly installed, you have 4x the jets to clog + change and deal with. A single fogger just hooks into your intake, and you're set.
Nx stuff guarenteed for life? Thats news to me, i'd love to hear where that came from. I got some parts i could use replaced :D

edit: again, all of this has been done on the type=s engine. keep that in mind when making decisions.
Nice post Warm Pepsi! Nitrous doesn't kill engines, Stupid people that use nitrous incorrectly does! Most people that run nitrous only use it in racing situations or purge half the bottle to look cool. To some people nitrous can be addictive. That can get you in trouble. It's what i call "trigger happy". Say a guy is running a 75 shot. He's fine for a while, but it gets old and he wants more power. So what does he do? Up's the jet sizing. It might run well for a few times but eventuially it will destroy the engine. 20 hp per hole is a good limit for a stock internal engine. With more nitrous comes upgrading the pistons, rods, fuel system and ignition system. Ever heard the old saying "If you want to play, you gotta pay"? If you want i can explain why dry kits will not work properly on our cars. Just ask.
we're all k-series people, and someone asked me what the site was for the new si, so i decided to shoot over here and see if there was anything i could answer. I forgot i'd even already registered :D
heh, i'm not the most knowledgeable with dry either, only know what i've run, wet.
a bit of flaming in this post, but a fairly good "owning" post about why you don't use dry ;)

really, you need more fuel? i would have never thought of that. well there are two ways, apply more pressure to the injectors by applying nitrous from the solenoid when activated or increase the amount of time the injector is on. always check for your specific application when ordering a dry kit, b/c if not having a return line will make us unable to increase press. to the injectors (if anyone knows the answer to this question i would like to know, thanks) or not being able to trick the ecu into making the injector pulse longer, you will obviously not be able to run a dry kit b/c you need extra fuel. i havent inquired about dry kits for the civic si so i dont know if there are any out there that would work. and there is a limit to how much extra fuel you can run with those two methods. which is why they are limited to such a low hp setting.Originally posted by Vertigo
Yup! I'd love to see how your going to get the extra fuel when spraying. Please enlighten us all. Like 2k2ep said, please film it.
oh, one more thing, running a wet system on an intake manifold designed for air only (unless you have forced induction or are using a dp sys.) you run the risk of creating fuel puddles in the manifold and backfiring. sorry for the sarcasim in my previous post
Now I wonder how long the motor lasts making weekend passes at the dragstrip? Especally with stock plugs and a basic wet kit at 125 shot! I'd guess either you never have done this to your car or you will be one of those lucky n20 users everyone hears horrible stories about.
me? I never said I was the one running it. I'm simply playin with a 50 and 75.
Feel free to browse on over to clubrsx, and take a look at some of the threads. Hell, Az, owning a base auto, put a 125 shot on it... it did no damage unless he got burnout happy and turned down his window switch.
Nitrous in the K series doesn't do anywhere near the damage that you're thinking. The only causes of failure have been user error. (spraying too long, in too high of gear, spraying at too low of rpm, selenoid failure).
And don't go and say that it was only a bottle or two, these guys have gone thru dozens with no issues.
All I'm trying to emphasize is that nobody should run 125shot on an all stock motor. You talked about running a 125 like it was it was a walk in the park. Its not safe for anyone to run the setup you described. Espically not a noob to the stuff.
oh, i totally agree, but the fact did remain, it was done with no timing retard, no nothin. more balls than i have :DOriginally posted by 2k2ep

same goes with hondata + n2o. with progressive controllers, it has been done, however, nothing i wanna play with
I spent a long time researching nitrous last year even though I had the hondata flash. While it's true that hondata and n20 can play well together, it's not entirely proven for how long or in exactly what manner.Originally posted by WarmPepsi

Doug (from hondata) put a 70 shot in NUGs ep... NUG had the original n/a hondata flash and it worked fine... I think they even accidentally sprayed it once without the "jet" nozzle even installed and had no problems. This is on dyno and on the track from my understading.
Anyway, me being a "noob" to nitrous and having hondata ... ive been wary to do it. The ZEX kit with the controller/mixer box all in one looks fairly safe. The kit that was installed in NUGs ep was the Edelbrock direct port.
Take it for what its worth.
yeah, we had a guy go though it after he got hondata ( already had a Nos DP setup) i called him nuts, but alas, he had it workin just fine, but nothin i'd ever do...
my system is just for fun when i wanna go.
great hearin from some other people though, you can only explain how switches and relays and pills work so many times before you're just repeating yourself :D
