Zex and NX are the most popular.

I just learned recently that the Zex kit is Crank HP. so the 55/65/75 shots that come with the kit are Crank HP.

Whereas the NX kit is estimatedly wheel HP. The 35/75/100 shots that come with the kit are WHP

Zex now too has a wet kit that inject fuel into the intake.
Zex items all go into a little puple box to take care of all fuel/nitrous.
Zex has a built in auto-shutoff if fuel pressure drops too low.
Zex is purple and kinda gay looking.

NX has the most options so far as extras. They do a direct port setup.
NX has a Gen2X kit that comes with the fuel pressure shut off/warmer/purge/blowdown tube. It costs anywhere fro $340-400 from any dealer.
The NX kit has solenoids that are seperate and in small cylindrical units that bolt to the firewall. They are not as organized as the zex and are becomse a more complicated install.
Zex is all brushed aluminum on the solenoids and the bottle comes in an array of different designs including the white bottle as well as a carbon fiber one.
NX parts are more expensive than Zex parts when it comes to the opener and other options.


Here's prices from a guy I'm thinking of doing business with.
Zex "wet" = $515
Purge = $109
Warmer = $93
(I may have the purge and warmer prices mixed up)
Opener = $195

NX "wet" = $535
Gen2X Kit = $340
Opener = $212

Note that the blowdown tube missing from the Zex setup is not that necessary really. It is a cheap upgrade from Zex and I don't know how much exactly though. The price difference basically is that the NX kitis about $100 more with a similar setup if you go and get a Zex blowdown to make up for it.

Both are similar in price and gains. Both have really good support. They're the leaders in the nitrous market until you go towards the Venom 2000 system which I don't think is tuned for our cars. Iti s completely computerized. Seems very straight forward and pretty damn cool. You can set different ranges for different shots. Therefore in your low end you can be running a 35 shot and in the top end a 100 shot.

thanks civic4982 for the info. big help. are you actually gettin a kit?? if so lemme kno which one u get and how the install goes. im still jus contemplating it. would prolly get headers first anyways.

Wtf is the blowdown tube? I was at Pep Boys yesterday (looking for a tag cover mind you) and I saw a Nitrous display - they carry NX in the store...kinda cool. They had that kit you speak of, but as I recall it didn't have the purge included. The kit was like $225 or so and the purge was another $125. Anyway, they had those blowdown tubes - it acutally said "NHRA Aproved Blowdown tube" and there was another NHRA part to, a pressure check valve I think.

civic4982

you have to have the blowdown tube for the tracks... it blows off pressure if it reaches too high of an amount. It's absically a safety precaution so that your bottle doesn't blow up if you levae the heater on too long and the pressure gets too high.

I do'nt know what kind of NX kit you're geting for $225 but it's probably not the right one. Generally a NX kit for 4-6 Cylinders is abou $500-$600 depending on distributor.

The only one that comes close to the $225 is the "incognito" setup which is basically a half ass setup that is a POS. don't buy into the pricing.

proaudio22

I mean the accessories kit. They just had the purge kit seperated form the other stuff. The actual nitrous kit was like $550.

Gotcha on the blow down tube. Does this tube need to be routed out of the trunk? IE drill a hole? I would assume so...

Btw, I've seen those pics of the guy whose bottle exploded in his truck while in his garage b/c he left the heater permently on. Not good. I like the check valve/blowdown tube idea.

civic4982

well there's an easier way to prevent that exposion proaudio... wire the whole nitrous setup to a remote switch (like on a stereo) so that it only turns on when the key is in and power is given. no heater on, no exposion...

SiGGy

Been asked so many times, I figured no one wanted to repeat themselfs...

Looks like someone didn't mind though

SiGGy

You can either drill or route it though a rubber plug...

I've never had one on my setup.



Also, unless this is a new rule. I haven't heard of it at all tracks....

pimpscls

i wanna get one but are they bad for the engine

civic4982

pimpscls... if you have to ask then you shouldn't get nitrous...

proaudio22

Right, but given the heater somehow gets power, it's nice to know the bottle would just blow off the excess. Thanks for the info.

You don't need one.

I have blow-off installed and it dumps right out of the left side of my bumper. Never had to use it, never will. But yes every track that I have been to requires it on any nitrous setup.

power3dfx

mtbikr,
i would kill for that engine bay. clean as hell with everything someone could want. have any track times?

njtls2

blown and on spray?

I have also considered using nitrous. As I understand it, it's a good idea to use "colder" spark plugs if you install nitrous. Also, I know our cars (CL-S) run rich, but is it a good idea to install a fuel pressure regulator or Comptech fuel pump to insure that we don't run too lean in the upper RPM range? I guess since these newer nitrous systems have alot of fail-safe's it's not that necessary, but does anyone have any insight as to weather upgrading the fuel system would be beneficial when using nitrous?

Also, I was talking with some employees at a local performance shop (Carboy) about using nitrous. They said using a wet setup is the best because if something goes wrong only the intake manifold would be damaged, whereas with a dry setup there would be a greater amount of internal damage. Does anyone know if this is right?
