im not to familiar with nos..i know mostly about what it does, etc..but i was wondering which is the way to go? i have a 95 civic ex?? is there any difference, etc. thanks in advance

edit:

Is this a good deal??

here is what i get:

Nos Brand Dry shot Nitrous system

2 10 LB bottles with Hi Flo valves

14 foot of line for front engine cars

5 Jets 25 50 65 75 Horsepower

Special mr2 install line for mid engine cars

NOS part no. 16020 powershot solenoi

Brand new full throttle switch

NOS 10 LB bottle Brackets

all for $299

is there anythign missing in that deal??

That seems like a good deal. However, for $50 more, I got a bottle heater and nitrous presser guage. I have Zex too. Not sure on which is best.

Here is what I have come to the conclusion of based on reading...
-75-80 shot and less > single fogger dry setup
-80 shot and more > direct port wet setup

IMO dry kits are terrible! But some people like them. However the one thing that I did not see in thre pics is the fuel pressure riser that has to bump up the fuel presure when the nitrous is flowing. With out that the kit will destroy your motor. I would suggest getting a fuel solenoid and a fogger nossle and go wet. :2cents:

Wet is definitely better. Running straight nitrous (dry) is very dangerous and much more stupid, is a way you can put it. But I woul also get that bottle heater too. N2O must be kept at certain tempaeratures for maxmimum performance output. Also I like the idea of having an electric bottle opener, its really nice to just open up and close the bottle at any time with the flick of a switch and not having to manually do it everytime.

I have heard bad things about wet single fogger nitrous systems having the fuel puddle up and then igniting. If you are staying around a 75 shot or less, I would just get a dry system. Zex has not sold millions of their dry systems because every car blew up that uses it.

I have been using one for 3yrs now, and i have freinds that have been using then for a long time too. And nobody has had any problems with them. The thing that causes the fuel puddle is when you spray with the bottle pressure below 800psi. A bottle warmer and pressure gauge will take care of thet problem. Also I know of 3 people that have had the ZEX kit here and all of them blew their motor within 1yr. And that was with 50hp shots and i have been running 65-80hp shots for 3yrs and my compression is almost to spec, which is really good for a motor that has 130K miles. Zex dry kits are terrible IMO. And BTW all of the guys who had the zex kits had detonation problems in the #3 cylinder.

I guess it just depends on people behind the switch. Do you happen to know if they had an aftermarket ignition, colder plugs and such or did they just slap it on and go?

Bottle pressure has nothing to do with fuel pudding or not in a wet system. Nozzle placement and intake manifold design have everything to do with puddling. Don't worry about puddling on a honda motor, the intake manifold is a pretty straight shot right into the ports, you shouldn't have any trouble. It's with a long runner intake like on 5 liter mustang where theres curves and bends that you can get problems with puddling.

You don't have to have an aftermarket ignition kitto run a 50 shot. And yes they had colder plugs, one of them had the three prong Zex plugs that are 2 steps colder, which is more than adequate for a 50 shot. Lookl at it this way you are reling on the IM to distribute the nitrous evenly but it will not and most of the time #3 cylinder will get more nitrous than the others, but the fuel injectors are only suppling enough to cover an even distribution of the nitrous and this causes a lean condition in #3 cylinder. Plugs, ignition etc none will help you when you don't have enough fuel for the nitrous! But when you use a wet kit it solves this problem by suppling the extra fuel and atomizing it with the nitrous so even when the cylinders don't get the same amount of nitrous it is still the right ratio of nitrous to fuel. See my point? I have been using nitrous for long time and know alot about it, trust me wet is better if you are planning on using it much. But knowledge is the key with nitrous period! You have to know how to use it and how to respect it!! And you have to kknow exactly what is happening when nitours is inducted into the motor ( ie. you have to know how it works).

is nitrous express a dry or wet system?

NX is a wet kit

cool :icon16:
i think when i get my next vehicle ill go spray. don't have the cash for boost :rolleyes:

That is why I personally converted my Zex dry single fogger into a direct port setup. It wasn't hard and its probable a good idea for other people.

I still dont know about that fuel puddling of a single fogger wet setup. :shrugs:

...I still dont know about that fuel puddling of a single fogger wet setup. :shrugs:

I am 24 yrs old and ever sense I have been around and involved with cars, which is most of my life I have never seen that happen to anyone. I think if it did happen to some people it would be because they installed the nossle too far away from the throttle body or they had a way too large fuel jet in for the amount of nitrous they were spraying. I still don't like the dry kit because even if it is direct port, what controll the amount of fuel added? Honda's have MAP sensors not MAF sensors. So the Map is not going to pick up on the nitrous and even if it did the oxygen contained in the nirtous does not get released until like 500 degrees or something. All that is controling the amount of fuel is the pressure riser that uses nitrous pressure to raise the fuel pressure, but it can only go so far! The fuel injectors will only spray so much fuel and the duty cycle needs to be changed and not the fuel pressure as much. Can you see my points? These are some of the reasons I always advise people to go wet instead of dry.

Well, you aint got too many years on me. :) However, you probably do have more nitrous years on me. You are right, the ones that I have heard of puddling up with fuel might have been install by careless idiots who did not know their butthole form a groundhog hole. And you are right about having to rely on the pressure riser to add adequate fuel. However, with wet kits you have to rely on the solenoid to add adequate fuel and well solenoids go bad. You just never now each way I guess.

Yes solenoids do go bad. And yes that would create a big problem. But they don't go bad that often and if you get some solenoids other than the super powershot then you should be fine but the super powershot solenoids are crap IMO. I have had 4 die on me. Now I use Cheater noids :iceslolan Going Direct port also with a 100 hp shot. :evillol:

Direct port also with a 100 hp shot
Been there, done that, and with a dry setup too. :iceslolan I backed it back down though cause I did not have too much faith in the Zex fuel riser. It is a real kit in the pants. :evillol:

Are you running an NOS single fogger?

Yea I am running the single nossle NOS system right now but I am upgrading to direct port before i run the 100 shot. I got 3 extra manifolds around so no down time. :p

hey are you guys running your nitrous where it kicks on at full throttle or at the press of a button and if at a button when do you hit it in every gear or only in like 3rd cause i want to run nitrous but i dont want to hit it and have it over rev in like 2nd gear oh yeah i will be running it in a 91 crx with a b18a motor with i/h/e and other things like ignition colder plugs etc; thanks

it depends on your experience since you havent ever used nitrous i would sugg a dry kit from zex at a 50 shot also upgrade fuel pump, and regulator and then when you feel more comfortable up the jet size

I love my Kit but just to warn you when you first get it and you feel all that power its going to be hard not to use it. But you will feel BIG difference and your car and power.

(I dont think the old ladies like it when i spray on them)

Hey whtteg are you running nitrous on a stock engine? Because I always thought that was dangerous? But im just a n00b :)

I run my on stock enigne and it seems to be ok

Yep stock internals with 135K miles and been on the bottle for almost 3yrs now. Still runs great. It is all in the tunning and self control! If you ever decide to use N20 then remember that.:biggrin:
