Alright i just got a 50 shot of zex for my 95 gsr. What i heard is i need to bump my fuel pressure up on my fpr. This may be a dumb question but would that be more pressure or less pressure on the gauge. I heard that the more pressure u have the leaner u run. He could of just been a dumbass, so any help i appreciated. :rock:

If you bump the fuel pressure it'll run richer. And dry kits already do that, if it's wet then you don't really need to do screw with fuel pressure. These kits were generally designed for stock fuel pressures, if you up your pressure and run it richer you'll just be killing power.

Literacy is your friend....just kidding. If it's a wet kit, don't worry about it. ZEX is an idiot proof nitrous company. Everything is contained in a "brain box" so there isn't much that can go wrong I hear. If it's dry, by all means, up your pressure about 2 psi for added insurance. I am TOTALLY against "dry" firing of nitrous, it's just too risky to me. Anyhow, that's pretty much it... :hs:

I was replying to him for saying just read the damn directions. But does anyone have the wet kit directions :wompwomp:

I'll explain to you how to hook it up. It's easy, a stoned monkey could do it (they have actually). ANyhow, hook the line that says "fuel" to a pressurized fuel source (probably your fuel pressure test port). Hook the one that says "Nitrous" to the bottle feed line. As for the electrical, the wires exiting the "brain box" should be marked. One for power, one for ground, and probably two more going to the arming swithc, and WOT switch (or hand trigger). Not complicated at all. Try wiring a home brew setup, without a kit....gets real fun, especially when using multiple relays.

Have you tried looking for directions?
Dry kit instructions? (http://www.zex.com/Technical/Instructions/DryNitrousKit/DryNitrousInstructions.pdf)
Wet kit instructions? (http://www.zex.com/Technical/Instructions/WetNitrousKit/WetNitrousInstallation.pdf)
Did you get a bottle heater? (http://www.zex.com/Technical/Instructions/BottleHeater/ZEX118.pdf)
What about the purge? (http://www.zex.com/Technical/Instructions/PurgeKit/)
Bottle opener is always nice... (http://www.zex.com/Technical/Instructions/RemoteBottleOpener/)
Need recommended jetting? (http://www.zex.com/Technical/Instructions/NitrousTuneUpSpecs/)
Still have questions? Here's an FAQ. (http://www.zex.com/Technical/Help/NitrousOxide.asp)
Jesus Christ, I didn't even have to use Google. I'm all for helping people out but goddamnit at least take some initiative.

i personanly dont recomend you running that kinnda kit on your car ( if its a civic or integra) becouase of the way the inatke mani. is made unless it is a diret port system i promise you will blow it up becouase all the nitrous is going to go to the least restrictive path with i garrentee you is never where you want it. i have seen so many honda, integras blow up on 50-75 shots becouase they where using this type of system. i would be surprised if you made it down one pass unless u take extra percations like i did
1. 2 heat ranges colder
2 at least 93+octain booster
3. retard timing a few degrees
4. bump fuel pressure
i did all of those things and was still scared shit less everytime i activated the nitrous. but hey you dont have to listen to me man ima dumbass and dont know shit.
[SIZE=1]yea right
