And other then that a blow off valve as I said before will release the exess pressure in the system that is unwanted.

Nitrous setups are usually designed to come on at WOT and only then when activated by a switch or button. How often are you at WOT everyday...and how long do you stay there? I think the most common kits are 50-75hp kits as well. Real engine blowing power there.
And also if it is not dangerous to your engine than running your engine lean is good for it, huhhh. Humm no it's not, running Nitrous causes exess heat and causes your engine to run lean, unless you get the proper fuel air ratio, and from what I understand it is very hard on a rotary to run it lean. Or maybe you can correct me once more on that one. Hell just steer me staight.

Well a little more posty right here, a wet intake NOS system should not be used on a dry intake car, seeing as how the intake has tighter turns and is ment to just flow air not air and fuel, or air and fuel/NOS, so a dry intake NOS system should be used on a fuel injected car, unless you have converted your car to carborators.

Don't listen to Cory Simpson on any of this. Seems like he got all of his knowedge about NOS from F&F.
Listen, what does a turbo do? Adds more air into the engine. In air there is oxygen. More air+more fuel=more power. That is why turbos produce more hp.
Now N20, when compressed, simply delivers more oxygen. A small nitrous boost is equivalent to a few extra psi of pressure. N20 is just like a temporary turbo. As long as you have fuel it's no more dangerous than a turbo.

All I know is, N2O is perfectly fine if you set it up right, and N2O in a Turbo car is definatly doable, you just better know what your freakin doing and get it setup real good. Anything can be done, its just a matter of how much tuneing you want to do and how exact you are going to have to get that tuning.
Personally I would not suggest N2O in a Turbo car, if you want more power then just start modding your car to handle higher boost and/or bigger turbo.
Just my 2 cents.

hmmm where to start with you... well first off nitrous oxide isn't a highly flamable gas. The previous guy was right, it just delivers more oxygen. Basicly it is a turbo that is pressurized in a HPA tank released by a solenoid switch. Friction creates heat, if you have a crazy boost set on a turbo, it will create just as much heat, so essencially... its the same thing.

finish your chemistry and physics class before u talk.
Thank you very much I have a B in chemistry, I just had a brain fart and thought that NOS was flammable for some reason.

2. Running lean is caused by lack of fuel. You need to tune a nitrous system to add the correct amount of fuel.
3. I have tuned several nitrous systems, and worked with Sean in setting up my current system. It is obvious that you have never set up a nitrous system, let alone tuned one. How can you possibly offer an opinion when you know it is based in inscience?
4. Nitrous does not cause excess heat, it causes higher combustion chamber pressures. This is responsible for the extra power.
5. Nitrous, superchargering, and turbocharging all simply add air. If you add the correct amount of fuel to the mixture, it will run perfectly. An engine making 400 hp properly tuned with nitrous and an engine making 400 hp with a turbo will have the same approximate engine life.
6. Until you have first-hand knowledge in this area, please keep your comments to yourself. There is no need to promote nescience, it just makes you look bad.

You will notice that the manufacturer's ALWAYS state to use a wet kit on a turbocharged car, EFI or not. Could it be that airflow has something to do with the picture?

Wow, I understand where the nitrous folk are comin from, because hey, there's nothing like the throttle in a bottle... BUT, i've had my share of car experiences with myself, my friends, and my club, and have never had a good experience with nitrous. I'm not going to go technical because it's just not needed. From my experience, a properly tuned bottle will not be as reliable as a properly tuned turbo. Period. I repeat... FROM MY EXPERIENCE.

wow, the guy with no rx7 is smarter than all of you.
Nitrous is NOT RECOMMENDED on a stock turbo because, well, you'll just have way more exhaust available than it will know what to do with.
Turbos don't need excessive amounts of nitrous, anways... that's what the turbo is there for, just turn up the boost!
A small amount of nitrous on a turbocharged car (50 shot or so) can help things by eliminating lag and cooling intake charge temps. But there's really no need for lots on a turbo car. And REALLY no need for any on a stock turbo car.

Why do people book dyno tuning with a wideband for their Turbo cars, yet expect to just pop in a nitrous jet and expect to have the car run perfect?

Look kid you need to get to know our car befor you start putting things on it that can and probably will kill your engine. Second you have a TII you do NOT need N2O all you need is some fuel mods to keep her brom blowin up and then open up her exhaust and intake. Like the guys above said you will run some great numbers with those BASIC mods. Third N2O is ghey and runs out quick specially if you race a lot(me) I don't want N2o because it is ghey like that (unless you have enough NAWS to blow yourself and the engine up) you run out of juice you suck again.

Take the advice of some of the people here, do the breathing and enginmanagement first.. ( intake, header, downpipe, exhaust, hi flow cat, fuel computer, or piggyback.. staying on the inexpensive side.. actually APEXi just lowered the cost of the S-AFC to something like $289 )
On my 91' NA I have N2O but before I did that I did aa street port, a new shiny stainless header and high flow cat, boxed intake and I put a B&M fuel pressure regulator and PF guage on my rail, along with an HKS super AFR and even then I'm only going to ever run the 55 shot. N2O is nice but the modifications I've made to it already will get it into the 200+ hp range from what I've heard , as I've yet to dyno it..
one thing about N2), when it enters the chamber it's cold, very cold in comparison to ambient temps, to break N2O into it's parts it requires @ 575 degrees and allot of pressure, when it does break apart the reaction absorbs heat cooling the chamber down even more and the N2 also acts as an ignition retardent ( like lead or octane)
One thing if you do do it.. be aware that the nitrous gremlins will strike if you don't have self control.

You don't know what you're talking about, you have no experience in this field, and you've obviously just been schooled by those who have the knowledge.
The smart thing to do would be to keep yourself quiet to try and minimize the damage.
Sorry Cory, but it makes you look pretty bad when you get caught spouting off about something you obviously know jack **** about.

Nitrous on a turbo car is used to help before spool up. Most guys who run it with a turbo setup don't run much more than 50-75 hp hit till the turbo spools up then it shuts off. Helps with quicker spool up on big turbo cars where lag is a big issue.
If your tuned right you will not run lean with Nitrous. Thats why most poeple suggest using a wet system. I have never run nitrous on a rotary engined car but I have had several different kits on my V8's back in high school..(late 80's)Three of them were N.O.S. brand systems and one was so old it didn't even have a name on it. Just a plain nonfinished metal bottle and a plain ol injector plate with a non adjustable 100hp jet bar in it. I ran the 100 on a bone stock 301 pontiac and the other 3 were all cheater systems run from 150 to 250 hp jets in it on 2 different cars, never ever had a problem with a motor because of Nitrous. N.O.S. brand is good, they been around a long time and I would trust any system from them. I'd stay away from the "rice" NOZ kits and stick with a reliable proven name if you feel you must use the gas. Most people look down on you though for using it when you haven't even tried to properly tune your engine first. Get an exhaust, intake, fuel pump, boost controller and get it tuned up first. If your still not happy then try a Nitrous system. you'll need an afternarket fuel pump before you got a N2O system anyway.

nitrous is a power upgrade...just like a supercharger or a bigger turbo. before you can do any of those, there are certain steps you need to take to make sure your car is capable of handling the extra power without breaking down. that being said....i have nitrous in my rx7 and its great. but i have a thought out and tuned system with enough supporting mods to keep it running on the rich side. nitrous actually cools the intake charge up to 75 degrees. and those who say nitrous is gay either dont have it or dont understand it.
