what are needs to be done to install NOZ

i have a 94 Z and a lot of miles on it, 115.000 miles, is it safe to install NOZ? or should i get my engine and my fuel injection clean out first? also will my tranny strong enough to handle all the power? i have 2.73 tranny, thanks for all the info...people told me to worry about ignition and rev limiter? can somebody please explain this to me..i dont understand what a rev limiter is and ignition has to do with nitrous? thanks for all the info.....:)

What is NOZ :confused:

Well,you kinda need to know what you want first. NOZ is nothing,doesnt exist unless you live in Fast&fictional. ALso your trans isnt a 2.73,that would be the rear gear.

Based on your questions, I recommend that you keep looking around the internet and learn more about your vehicle before you begin to think about modifications...

I'm sorry I shouldn't have said that..........

Go with a wet kit, it'll be cheaper because it doesn't use your injectors to support the extra fuel so you won't need to replace them. It just screws into your fuel line on the intake, fairly simple there's a test port already on the fuel line and you just screw it into that. Your trans shouldn't have any problems if you keep it around a hundred or shot, which you will want to do anyway cause from what I hear that's all the stock fuel pump can support. You'll also want to think about an ignition to cause if you hit the revlimiter you'll ruin your motor.
Good luck, I'm still learning to.

So what about puddling in the intake. You wouldn't be worried about that? I only ask because I'm tryin to figure out which kit to get. I'm going to go with either the TNT 100-250 system or the NX GM EFI race kit. They are both wet kits but I've been told I would be better off going direct port. I agree to that but Do you have to go direct port if you plan on pumping a 200hp shot of nitrous? Is there anything you can do to ensure that a regular wet kit will not puddle in the intake of an LT1?

To prevent puddling you can leave the stock intake alone, from the research I did you'll be safer going with a wet shot. Considering your using the stock injectors. Although it's true about puddling from what I've heard the stock unfinished intake is a bit rough and grouty on the inside, which helps prevent puddling on the walls because there is a slit bit of turbulence around them. If the intake were polished smooth I could see where the dry shot would be a better choice, and I'm sure from a technical stand point the dry shot is safer when you run upgraded injectors, but on the other hand I have never seen a back fire on a stock lt1 intake with a wet shot. Also if you end up wanting to go with a 150 you'll want to run bigger than a 24lb injector on a dry kit which means on top of the 300 for injectors you'll also have to pay for a reprogram to run the larger injectors.

Edit: didn't finish reading krsones post. I'd say the bigger the wet shot you run the more risk you have of puddling on the intake cause there obviously will be more fuel in there. From what I remember from the searches the biggest shot was 150, so who know what the extra fuel from the 200 would do in terms of puddling. If you have the money go for the direct port if not to be safe I'd only run a 150 wet. As for who makes a 200 i think there is a kit the replaces your maf ends and sprays threw them. I think tnt make it but am not sure, it said it was good for up to 300 shot for 94-02 f bodies.

can someone explain to me about the rev limiter and the ignition...thanks

I have been running wet systems for about 8 years now.NEVER had a "puddling" problem. UNless the fuel solenoid sticks open,or you go WAY big on the fuel jet,you shouldnt have to worry.
As far as the shot size,many guys have sprayed a 200 through the NX single nozzle.
Also if i remember correctly,the stock rev limiter cuts fuel,not timing,which is BAD when on the bottle.

And one last thing,SnakeatinZ, If you actually READ what i posted the FIRST time you would of seen i shed some light on his question. Not my fault i dont know what "noz" is.

Can the stock internals handle a 200 shot safley or would you have to go with forged pistons?
If I were to go with a 200-250shot I was probably going to put in forged pistons and robs, but wanted to know what you guys thought

I just got edited for not playing nice.

People like this guy make me wonder why i even try to help people go fast. Snake,what are you trying to accomplish,wanna start a flame war? :rolleyes:
BTW it's N2O ,not NO2 or "noz".

I'm all for guys running nitrous,but at least KNOW what it is,whereas you seem to be a tad confused like the first guy.

As far as going above a 200 on stock internal's thats REALLY going to be pushing it. If you run above the 150 shot,make SURE the fuel system is in TOP Notch shape.Also make sure to run a colder plug ( i would go colder than the TR6,and will be switching soon). Also you will want to have all the typical safety equipment.

Thanks for all the help guys!

hey snakeatinZ,

If you can't spell, you obviously can't learn, so why would we want to teach you, especially considering your poor attitude?

Hey RacinLT1,

200 shot is no problem, been doing for 3 years on a stock LT1 bottom. However, as you mentioned, a top notch fuel system is a prerequisite. Mine is redone 100% from the 20 gallon aluminum fuel cell, the Aeromotive pump, -10AN lines, Holley regulator, etc.

I've been running 93 octane Shell or Amoco, 33deg total timing, TR6 plugs, Magnecors, all Crane ignition, no knock sensor at WOT.

Dirk,

I myself consider you one of the best contributors to my favorite corner of the board. :) Don't let the Diaper section chase you away.

George, we need your knowledge in here more often bud! ;)

and as for Snake, well, play nice or not at all.

I knew what he meant, I was being sarcastic. It really looks like he needs to learn more before he starts doing stuff like this to his car, judging from his post. Also, TMD, ya gonna need more then 1 header... ;)

George, we need your knowledge in here more often bud!
Hey Kurtis,

Thanks for the invite :cool:

Now as to the diaper section, one of the reasons I haven't been on here too often is that I tend to get a bit huffy and sarcastic with people who are unwilling to even do basic research. I have been known to do some flaming :p

I mean really, NOZ??? NO2??? NOS???

I guess my NX system has no NOS, and definitely no NOZ or NO2 :D

What I would really like to see is an advanced N2O section. I've learned quite a bit in the last 3 years, things which I never would have suspected. Even simple things, like how the nozzle angles greatly impact HP, or how much NA power you lose every time you hit the button, or how little many of the Nitrous company techs really know.........

Good idea about the "advanced nitrous" forum George.

sadly i still dont know why NO2 will hurt my ignition or my rev limiter, can someone please explain this to me...please guys...thanks.....btw i'm really a beginner, maybe after taking some mechanic classes than i'll be able to understand...sorry to bother:)

Kurtis,thanx for the kind words. Glad to know someone likes what i have to say :D

TMD,it WONT hurt the ignition OR rev limiter. and it's N2O.
Anyway,if you want to add it to YOUR car,make SURE you have a good ignition system and use a window switch. A bad ignition can lead to detonation which will KILL the engine. Also you dont want to hit the rev limiter while spraying....that could also cause big problems.

It may seem like a few of us have a hard a$$ attitude, but using the correct terms always indicates you have taken the time to learn a little more about the use of nitrous than the time it took to watch the "Fast and the Furious".......:D.

To be specific on your questions..... adding nitrous to your engine increases the load on the ignition system. It will not "hurt" your ignition system, but if the system is not set up correctly, and "strong" it isn't going to allow the nitrous to produce the power it is supposed to produce. It is very easy to see problems from an excessive plug gap or the wrong plugs. The larger the gap, the better the chance the spark will be "blown out".... no fire = no power. So, you typically reduce the stock 0.50 gap to 0.35". Using plugs like the stock AC/Delco platinum can result in the platinum pucks falling off, and increasing the gap to as much as 0.100". And, the extended ground strap on the plug can lead to detonation problems... so you don't want those plugs. And, you will benefit from a "stonger" ignition.... easilly provided by something like an MSD multiple spark box in the ignition system.

As far as the rev limiter..... N2O won't hurt your rev limiter, but your rev limiter can hurt your engine when you are spraying. The stock rev limiter cuts fuel..... you don't want to do that when using nitrous. So you need an adjustable rev limiter that will cut spark a couple hundred RPM below the stock rev limiter setting, or you need to use a window switch to cut off the nitrous a couple hundred rpm before you hit the limiter. I cut my nitrous at 7,000rpm, and have the computer rev limiter set to interupt spark to random cylinders at 7,200rpm, but my sytem isn't anywhere near "stock".

A good source for basic info on using nitrous can be found here:

Hope this helps.

thanks a lot guys, i'm very new at this, i'm just a young asian guy who want to get a fast car with a minimum cost, thanks a lot one more time, just one more question, after installing the no2, how much would it cost me to adjust the rev limiter, etc...thanks a lot for the help....i feel very welcome here.......

sid,

guy who want to get a fast car with a minimum cost

U need to be able to afford a new motor to go on the juice IMHO.

With that said u r not ready for NOZ.

how much would it cost me to adjust the rev limiter, etc...

I HAVE programed or jucie at the track with major sucsess on a nearly stock Z28. 12.6's @ slow ass Fontana! but it is all in the setup and parts. A nice setup is not cheap.

Keep your eyes and ears on George Debski he is the LT-1 No2 Jedi Master!

Yep! do it right and have a plan B ready........and its NAAAZ not NOZ:D

Do you think a nitrous-caused engine F-up would be obvious to the dealer :) ?
