zex Nitrous kit questions

hey first of all are all zex kits dry? Can a zex kit used on a 3rd gen work for a 2nd gen? is a 75shot kit safe? what about are the hp increases with a 75 shot zex kit?

it's not all NAAAWWWSSS....he's asking about the zex kit. Now this might seem harsh to you, but it's annoying when people call it nos and NO2.

I've never understood why people have such an issue with N²O, it serves the EXACT same function as turbo or superchargers, ie more oxygen for specific volume...
and it can be made to run all the time also, above certain rpm's

I ignore those people. Everyone should learn to do the same. Ignorring people that irritate/agitate you will add years to your life .

Nitrous, Nos, NAWZ, N02, N20, is all good!!!

I don't have a problem with it.
If I hadn't invested major $$$ into a huge turbo, and actually spent my time drag-racing, I would use it too.

Either way, it is used for more than just direct injection. People use is for IC sprayers, too.

The whole anti-nitrous backlash started when people wanted to prove they are not F&F riceboys, so being anti-NOS is just another way of proving that to the masses.

NOS is a brand name of nitrous oxide systems created by Holley. Some people are **** about it. It seems that the use of the term NOS instead of nitrous oxide has become more prevalant since the release of the movie the Fast and the Furious as the stars can be heard shouting "NOS!!!!" etc... Its basically like calling a copy machine a Xerox machine, or calling facial tissue Kleenex.

a kit should be labelled wet or dry. a wet kit will most likely come with some way to access your fuel system and add more fuel at the same time as adding the nitrous oxide. www.fc3s.org i believe has writeups of both a wet and dry NOS brand kit on an FC.

From stuff I read . People recommended the Wet system.

I saw a write up on installing that and OMG it was easy.
I'd like to do it cause I have 90k engine and don't want constant abuse from other FI applications.

Last time I looked Nitrous Systems had a Dry only system for our cars.

I'm sure it's a universal kit. They probably slapped a dry on a rex and said yup it works.

Just don't get the F&F edition nitrous and you should be ok.

If I had another car to use as a back up I would do it.

If you know you have probelms with your engine then don't mess with this.

I'd say if you have good compression then it shouldn't be a problem. Just make sure you don't use it alot.

I read the FC3S write ups but I didn't see anything on timing.
I would geuss you would have to retard it right?
How many degrees? Need different plugs?

I would geuss running a higher octane gas would give a little cushion for detonation.

75 shot dry is a little much. I'd be a little worried about that. anything over 50 that is dry is pushing it.. do it wet. MUCH safer. Worth the extra money and labor.

engine with 151K?!! My goodness! That's wild. No, I'd save it. Get a rebuild.. That poor thing won't be able to hold on to much, ESPECIALLY a 75 shot dry. Maybe if you ran it wet. But I wouldn't. Spend the money on a rebuild.

And by the way... NOS freakin' rules! Holley DEFINENTLY knows what's up. I have Holley "NOS" fuel injectors, which can be used in conjunction with a "NOS" kit that directly clips to my injectors for a wet nitrious application. Too bad that it won't work on mazda's (damn UIM sits right on top of the rails! It won't bolt back down!). But Holley makes a fantastic product. A friend of mine is running their kit on his mercury caprie turbo (mazda 323 turbo engine).

I love talking about nitrious. Gets my blood pumpin'... Can't wait to do my kit when I blow my motor.

What are you going to do when your nitrous runs out in the middle of a race and you loose $500?

Nitrous is not "just like a turbo".

of corse its not a turbo if you dont want to "RUN OUT" theres a little thing called a guage that tells you your low. and besides you have a turbo but you can also add nirtrous to be even faster you dont neccisarly have to put it in your engine along with the turbo you can spray it in your intercooler to lower the temps of your incoming air.

N2O is great. Ive said it before, and ill say it again....its only dangerous if you use it improperly. People who say its sucks "just because" dont understand it.

Get a wet kit. Wet means that the correct amount of fuel is introduced along with the N20. This decreases the chance of leaning out and blowing your engine. Most kits arent really "customized" for any car. They just have the right lengths of lines and etc to make it easier to install on specific cars. A FI kit will work for any FI car as long as you understand how it works although you might have to buy a piece or two.

Read up on the holley website and other sites on how N2O works and how to install it. Im not gonna say its just as good as a turbo or whatever cause itll just get people here pissed and they'll go on for 35 pages about how its not. Just know its a power adder like a turbo or supercharger. It just isnt always on.

"Just like a turbo" maybe not, but could be pretty close.
have a rpm-activated switch that turns it on @ 5000 rpms, you wouldn't hit it in normal driving, just when you've got WOT
make sure fuel is compensated (or go wet injection), keep the shot down below 75, you should not have any problems for MANY miles...

that would be cool but how do you set it up to work at a certain rpm?? i would set it around 4500-4750 cuz 5000 is pretty far up considering you usualy shift around 6-7k plus it usualy drops to about 4500-4750k anyways after you shift.
