Experienced N2o users - Honda Prelude Forum

macswhtaccord95 · 03-05-2004, 09:01 PM

Hey guys I'm looking for some info from you experienced N2o users. I have a 95 accord w/ a H22A. My mods are as follows: cai,header,fpr, walbro 190lph fuel pump, act xtreme pressure plate w/ street disc. I'm having a hard time deciding between wet vs. dry. I know the difference between the two. I've heard the deal about the intake manifolds on hondas' made only to flow air. I want to hear from you on your experiences with wet and dry kits on prelude motors. I'm looking at getting either a Zex or NX kit. All info will be appreciated.

How big of a shot are you planning to run?

If you just want to run a 60 shot or less a dry kit will work great. However if you want to spray above a 60 shot you really should look into a wet kit, as you are starting to push your fuel system. My NX kit has held up great, and I really haven't heard of any problems from Zex dry kits so you shouldn't worry about that. You probably should plan out how big of a shot you want to run before you choose what type of kit.

I'm only going up to a 75 shot, as my motor is not built. How long have you been running your NX kit? I take it that you have not had any problems with the fuel puddling in the intake manifold?

I've been spraying for a little over a year and haven't had any problems. To be honest I haven't heard of many nitrous motors going down. The few that I have read about were due to user error. You could always go to a DP setup if you are worried about nitrous/fuel distribution.

Cool thanks. I like the idea of using tps activation rather than a mechanical switch, and I know both the NX and Zex offer them. If I run a Zex kit I'd like to know if their nozzles atomize the fuel/n2o mixture as well as NX's. I know NX has a patent on their nozzles, but how much different can the designs ne between companies. I also heard that NX uses NOS's solonoids as well as some other components. Supposedly there are NOS stamps on some of NX's stuff. Any truth to this?

NX doesn't use any NOS parts, leaving many of us very happy when it comes to the noids. The NX noids are top notch, especially when compared to the NOS PowerShot noids. Many people here on PO had troubles with the PowerShot noids, yet nobody has needed to rebuild/replace an NX noid

. You might do some research on the ZEX wet kit, since it is so new to the market.

NX Wet Kit

NX rates their shots at the wheels so you get more hp than you would than NOS, since they rate theirs at the crank

That reason does not make one kit better than another. All NX does is use bigger jets to "make more power". It would be different if NX used the same size jets as NOS and other companies and made more power. Basically what they are doing is taking the equivalent of a NOS 80 shot and labeleing it as a 50 shot. After all, they all run on the same nitrous

Thanks axion68. Anyone else?

CTPRELUDE · 03-07-2004, 12:18 AM

I would go with a wet kit no matter what size shot you are going to run, but that is just my opinion. I'm sure you could run a dry shot safely to around a 70 shot, but I prefer wet kits.

I would also go with NX as no one has had any problems with it including me. Plus the fact that you really get a bigger shot out of them, which is cool too.

Good luck!

wet kit all the way

stevej37 · 03-07-2004, 06:45 AM

Zex dry kit....simple installation...using the tps wire. Using their air injector, you don't even need to drill your intake. Easy and very effective.

Toretto · 03-07-2004, 10:49 AM

If you never plan to go above a 65 shot, the Zex kit would work just fine for you. Zex is just so simple to install. The NOS and NX kits are upgradeable, so you could always upgrade to direct port down the road. Whichever kit you go with, Zex, NX, or NOS, you will be very pleased with the results.

macswhtaccord95 · 03-07-2004, 08:41 PM

I appreciate all this info guys. My motor is not built, so I won't be going higher than a 75 shot. N.O.S. was very addament about not putting a wet kit on a honda because of puddling and backfires. NX says it's highly unlikely because of their nozzles. Zex says I can use wet or dry, but dry is safer. I pretty much expected them to say these things, but you guys are the ones with experience though trial and error.

Does NX's tps switch work the same a Zex's? If so is it connected to the tps sensor on one end and a solenoid on the other?

NXLude · 03-07-2004, 09:29 PM

Go wet, go NX.....there is no reason that you will backfire unless you spray at a really low rpm or install it really wrong

JaXx4k · 03-08-2004, 12:25 PM

make sure ur wires are ran correctly n crimp them real tight. i had a loose power wire n it touch metal.

beside that after i reran the wiring everything ran fine...

axion68 · 03-08-2004, 12:30 PM

I'd imagine the NX TPS switch is connected to the relay that powers both noids. I don't recall anyone ever posting about having the NX TPS switch on PO, so you should contact NX themselves for any technical info. Aside from that the mechanical WOT switch provided in the kit works great; I don't see a reason to replace it.

laughin2.2 · 03-08-2004, 06:11 PM

My NOS wet kit had absolutely no problems with fuel puddling or backfiring. The ****ty noids and parts however did piss me off. 13.7 with a 65 shot and some wheelhop is nothing to sneeze. Get an NX wet kit, the Genx2 upgrade kit, and some BFG drag radials. Get the thing tuned and go to the track as often as you can. Some of these NX boys should be breaking 13.5s on a 75 shot by now and I have no idea why they aren't.
Edit: I'm in fayetteville. I'll be awake until about 1 am monday(today) and tuesday. My cell # is 479 790 2818. If you have any questions give me a call. That goes for anyone else as well. I've got a bit of a drawl though, so fair warning to everyone.

wat do you guys usually check for ? or utilize in order to minimize chance of engine troubles?
