Dry shot? Wet shot?

If you are running any more then a 55 shot with a dry system, i would suggest upgrading the fuel pump, running a step or so colder plug, and retarding the timing 2 - 4*.

 

yea what jv guy said....specially the colder plug part ignition system owns too.

 

Make sure your car runs fine first. Then just do a little with the spark. I ran a 65 shot of dry zex in my in my crx which was all stock with 165000 miles and it was fine!

 

You really dont need to do anything if your using a small shot like 55 but its always good to run a colder plug, add more fuel and of course like it says run 92 octane. I am running 55 shot wet kit on my d15b7 w/ 149k on it and it loves it.

 

i have a friend that has a dx with 174xxx miles and he runs a 75 shot of zex and it runs great. He does not use it much but he does every once and a while.

 

he does how ever have and msd ignition but he ran it with out if for a few months

 

I'm going to be running a 55 shot for now....The car only has 66000 miles....So I dont have anything to worry about with it?

 

dont boost in 1st gear, and u have to be ready to shift because u can blow a ring

also upgrading spark plugs is almost a must also 92 octane gas...and your set...it will take it if your carefful...just dont be a dumbass with it

 

Some of the info on this thread are correct and some are NOT so correct.

If you are using any type of force induction whether it be turbo or any amount of nitrous, it is ALWAYS best to make sure your engine is up on its maintenance. Make sure your car is running well before you toast it with a shot of nitrous... But if everything is running well then proceed: Make sure you retard the timing according to Zex's instruction. I think for a 55 shot you dont retard timing at all. 65 shot 2 degrees and 75 shot 4 degrees. Make sure you use they highest octant you can when you shoot nitrous to be on the safe side and make sure your spark plugs are CLEAN or at least new. I recommend just getting the ZEX spark plugs or get a 1-2 degress colder in NGK spark plugs, but it's your call. Just dont get freaken BOSCH spark plugs from Autozone or Kragen/Checkers.

No need to upgrade the fuel pump or get do any fuel upgrades. Zex takes care of your fuel needs by adjusting the amount of fuel it dumps into your engine with the amount of nitrous flowing through--the purple box.

If you are nervous about the whole nitrous deal, I say start at 55 and move up slowly to 75. With the low mileage on your car, you'll most likely be fine with a 75 shot of nitrous, but like I said do a step wise increase in the amount of nitrous so you can see how it handles and adjust your driving to it. You can shoot nitrous off the line and it wont mess anything up. Just make sure you are quick to shift and get ready for quite a bit of burn out! What I do is launch the car with the trigger "OFF" and as soon as the car hooks, I turn the trigger "ON". So I'm doing nitrous through all the gears. If you have slicks and are doing this at the track, shoot nitrous off the line and you'll get GOOD 0-60' times.

I hope this has been helpful and drop me a PM if you need some more info on ZEX. I've had enough experience with ZEX to know that its a SAFE nitrous kit to use with some precaution and a lil knowledge about upkeeping a car.

haha... thats why I said in my post that he could. he'll just get mad wheelspin if he doesnt know how to feather it or control it or doesnt have slicks...

 

Anyone have experience using this kit on an auto trans?

 

Dry kits dont control fuel though just FYI only ZEX wet kit will control the fuel. Wet is alot safer because you have the right amount of added fuel. I run my nitrous off the line as well and seems to do ok on street tires, slicks would most def help me though since I still dont have the greatest 60ft times.

2.38 60ft 14.97@92.86mph on a D15b7 55 shot

I did a NOS brand nitrous kit on my friend 00 EX auto and it seemed to do ok. It made is car a bit faster but still a slug so much power is just lost in a auto tranny.

 

The Zex dry kit DOES control fuel. Depending on the pressure in the bottle the Purple Box will increase the pressure in your fuel rail accordingly so that you get fuel compensation for the added amount of nitrous flowing through.

I agree with you that Wet is a bit safer. Wet kits also have the added of advantage of having the nitrous and fuel already mixed and nozzled together before it enters the intake.

 

Does it? I didnt think they did that, sorry maybe I am wrong I know with other brand dry kits they dont control fuel at all. Thats what I thought made a dry kit dry no added fuel and a wet kit a wet added fuel

 

the other dry kits dont control fuel because its just shooting nitrous from a solenoid into your intake but the zex does have some control over fuel--kind of like a FMU.

 

So theres nothing major i need to do to keep from blowing up the motor?

 

nope just make sure its already working and follow them directions that came with zex.

But for extra precautions, use the highest octane, check your spark plugs, retard the timing, and check all your wirings... Thats it! Go spank some V8's! haha

 

i ran zex on my car for a few months

i just ran 2 step colder plugs (Actually ran the zex ones), i had a b&m fpr, and a injen shorty intake... that's all. was fine @ 55 shot

Every dry kit must have some way of controlling fuel, just not using the same method a Zex kit does. How are you going to run nitrous, even just a 55 shot and not compensate with added fuel?

 

My friend has a 98 civic coupe and he runs a 75 dry shot. I dont think he upgraded anything else.

NOS says in there directions you do not need anything else to run 55 shot besides what is supplied. In the box they did not supply you with anything to run more fuel to there DRY kit. There for NOS brand on this particular kit doesnt control added fuel to the system. If you want more fuel you have to go buy a upgraded Fuel pressure regulator.
