Alright gearheads...lets talk NOS!!! For my application, what do you all think is the best NOS kit for my car. 150 shot is what I want. Let me know if you have personal experience with the setup you recommend, and if you dont have experience, let me know why you are recommending it. Thanks.

Personal experience... Go with an NX kit... They are inexpensive, and they are a wet shot. You want to go with a wet shot rather then a dry shot... The dry shots basically max out the stock fuel system at the 125 shot... I called NOS tech while I was at work and they said that you should not run a 150 dry shot without doing some fuel system upgrades. If you want to run a NOS kit, run the NOSzle system... It goes piggy back on the injectors (so it is a dry shot that adds fuel at the injectors if you haven't seen it) and it is adjustable from 100-300.... granted your stock motor won't handle anymore then a 150 shot. Plus You need to think about how you are going to take out so much timing with a 150 shot. Your going to need to take out about 3*-4* of timing... I would not run the NOS dry shot again... I'm kinda glad it got stolen. That's how my motor got blown... The guys that took my damn car just f*cked with it too much. I only had a dry 100 (Modified 100) shot in there. They go by modified and non modified cars for a hp rating on their nitrous kits.
Ok Jeff here we go again, if you want a kit i had the N.O.S. kit #5171, on my car and as we talked before the only upgrade i made was the 255 LPH in-tank fuel pump, and i did not have to take out any timing, and i ran motorcraft platnium plugs gapped at 42 degress instead of or stock 52 degress. The car ran perfect with a 150 shot, i believe that is the highest that kits jets go, i would be leary about going any higher, as for the nozzles kit they have now, i hear it is the way to go, but once again we get into cost issues, N.O.S. kit # 5171 about $600.00, fuel pump $120.00, Nozzles kit and i don't know the # for or car's, price is over a $1000.00 but i believe less than $1500.00, they say that's the way to go now and you can increase the shot up to 300, but do you really want to go that high on stock internals. I know nothing about the N.X. kit, so i can't help you there, all i know is when i ran N.O.S. i loved it, and a dry kit is definitly the way to go, stay away from a wet system for your car.

Guess I should have stated that I already had info on the N.O.S. setup..oops... ...bad Jeff!!! Sorry Mark...dont want you to think I forgot our conversation. I talked to the speed shop guy about the N.O.S. kit and of course he says..."you need to go with NX" cause hes a dealer for them and he needs to sell a few more kits by the end of the year. Then a guy I met at the track says he's using Zex. So I just wanted to hear what everyone else had to say. The thing I worry about with a wet kit is detonation in the intake...I read somewhere that is not a problem with a dry kit. Let me know if Im wrong. And no I would not go higher than a 150 at all....I like my motor!!

Good, and as far as the Zex kit there is a guy in town that has one and he likes it, so it's all about what you want, Jeff you know it's like everything else we have to choose from in this aftermarket world. Jeff i also know someone that had the Edelbrock version and he did not like it, and if i'm not mistaken that kit only went up to a 100 shot, stay away from a wet kit, that's why there is a dry kit for our car's, think about it someone at N.O.S. designd a dry kit for the modular motors for a reason, probably works better with the internal's we have, i hade it and it worked sweet, i liked it, but i LOVE this better. Thanks Mark.

I sell the NOS, NX, and Edelbrock Kits at work. I would rather get the NX kit. Or run the NOSzle system from NOS. I've also heard Zex is really good. But I just don't like the NOS from personal experience.
I have the zex kit installed and love it, with the 100 shot I lowered my time form 13.7@102 to 12.7@110...so yeah I was impressed. As others have said it all about what you like, I have friends with zex/nx/nos/edelbrock and most like them. I choose the zex for the installation, if your good with tools, 3 hours. I choose a dry kit so I would not have to worry about pooling in the intake. A few things to remember: cooler plugs, retard the timing, AND MAKE SURE YOU ARE GETTING ENOUGH FUEL!! I hade a duel chip burnt, that way I can switch between a NA and nitrous tune...as you can guess the NA tune is a lot leaner. lol Anyway, the zex kit works off the tps sensor and comes on at full throttle, it safely adds the right amount of gas by how much fuel is coming in...more fuel more gas!! I go to all kinds of stang sites, and my friend did a real nice write up/intstall on the zex kit..check the link out. Lots of Q/A answers also. zex kit install
Good luck on which ever you choose, trust me it's a real good kick in the pants!!

I am a fan of the NX kit. It is a dry shot( which is safer on the 4.6 mod motors), hp is rated at the tires not crank, cheaper(depends on shop). I have heard good and bad about all. However i have seen more bad with all the others then i have with a NX kit. I plan on putting a 150-200 shot in mine, now my mod funds increased.
I am about to install a wet compucar my self. Dry systems tax the injectors greatly. 1 lean or out of calibration injector and 1 burned piston. With this said a wet kit can puddle in the intake a backfire breaking that "great" intake. Intakes are easier and cheaper than pistons. Then you have the ZEX system. Not the highest hp but about the safest. Do your research and put in the system that meets your needs. P.S. dont inhale.
I belive that the best gain's from NOS will be with dry NOS because
I heard to many horror stories about people running wet kit's.
The 100-300hp Pro Frogger NOS kit is awesome if your applacation
can handle it!
A lot of people talk about the wet kit and how dangerous they are when it backfires. I have a question? Is this mostly for standard vehicles or do auto's fall into this bracket too. I mean the backfire thing. Like my sig says I have a wet kit and since buying it 1 year ago I have only used it three times, from fear of the backfire tail. Please advice. Thanks
Any car that is running lean will backfire. Auto or standard. As long as you run good fuel pressure and setup the NOS system the way the manufacture tells you to you shoun't have any problems. I would pesonaly run a seperate fuel line and pump to the NOS to avoid low fuel pressure. People that run the same line for their engine and NOS are the ones that have all the problems

I run a single pump and single line for both sides and have never had a problem. Matter of fact when I ran a dedicated system for the N2O I had problems. 12AN from cell to BG5000 filter, 12AN from filter to BG400 pump. 8AN return line back to cell and a 10AN to a BG 1/2 inch "Y" block. 8AN to a BG 2 port regulator and then to carb, and another 8AN to a second BG 2 port regulator, from there through a Hobbs switch and then 6AN to the fuel solenoid.
Seems to work fine. I spoke with BG and they indicated that system will easily support up to a 1000 HP.
Your opinions on the different NOS setups..
