Calling ALL Nitrous Gurus...

[SRdS14]

OKAY...check this out. those that don't know, i have an sr20det. i currently am running a t3/t04e .82 A/R, 60 trim. etc etc. i have the fuel to back it up....

my problem is my turbo spools up around 4000. for the track, i'm have been thinking about running a nitrous setup. however, i DO NOT want the nitrous still kicking when the turbo starts to boost. i want it to start from throttle response on to about 4500rpms. i guess this means i need a computer controlled nitrous system?? i have no CLUE. will someone please further my knowledge on this. Like i said above, i want my nitrous to only work from throttle to 4500 rpms...if anyone has recommendations, etc...please let me know. i know about the basic nitrous kits, etc, but when it comes to this cpu controlled, i have no clue. Thanks VERY MUCH...

well im not much of a nitrous guru...really i have fuggin clue what im talking bout with nitrous BUT!! Venom does have some computer controlled systems that i am sure you could program to do that job for you or you could get just a plain old nitrous system and jam the button til you get to 4500 and then just be done with it. I think you should check out the venom system though.

Pick up the new SCC, they have a new Suck Squish Bang Blow article about nitrous in there. Good ****, you should read it.

[Nismo1182]

or you can use a msd rpm switch to turn the nitrous off when you get to 4500 rpms. The N02 will make the turbo spool quicker than the 4000 rpm your getting now. Be sure you use it wisely and not blow something up.

[Phax]

The Electromotive TEC series of computers can control the nitrous injectors, along with the fuel to back them up.

SCC is written by a bunch of Honda drivers who have no clu what a setup on a RWD car looks like.

NOS and NX both make boost sensitive switches for nitrous applications with turbos and superchargers. You should invest in one and set it to about 2psi so that when the turbo spools it shuts off the nitrous.

[Open4Cycle]

Location of the nozzle is criticle for a turbo, the expanding nitrous will spin the compressor if located correctly.

ok, i have done a nitrous setup before, oh but it was on a honda, like that matters, man whats your deal, like a rwd car changes the way nitrous works on an engine....no, anyways, first off go with a wet setup, thats where you get gas and nos at the same time, this is important b/c you do not want to run lean, 2nd if it is over a 50shot, then do not just slap the thing on, you need to tune it or you could run to lean and blow things up or you could run to rich and run slower than before, as for venom that is such crap, over a grand for a dry set up, no thank you, Nitrous EX, or Nos, is good, as for Zex just say no, anyways its a dry set up, yes i have used the MSD window switch, it works great, Nos when used right is really cool and fun, when used wrong well it can be your worst day, just do it right, you can also look into a Jacobs Master Mind, its a Nos Ecu, its soposed to be prety cool, it has the window and some othere goodies with it, good luck and oh yeah, maybe im wrong since i used to drive a honda...b/c there engines work diffrent when it comes to NOS:Werd

Since you're fairly new, and obviously don't know who I am, I'll give you a break...

SCC began as a magazine run by 2 Honda technicians who believed that the only fast imports were made by Honda. Today, it is still true of them. They are known to print incorrect figures in their articles, as well as to under-rate horse power produced by many non-Honda vehicles durring dyno testing.

About the nitrous...I am and have been a Holley dealer for the last 3 years. Nitrous Oxide Systems is a brand we carry. Nos as you so eloquently put it, is a brand name. Nitrous on the other hand is a compound gas that enhances burning durring it's expansion in an oxygen rich environment. Hence, the oxygen is copmacted and becomes somewhat easier to burn.

You don't EVER just slap a nitrous kit on something. That is how perfectly good motors become door stops. Every nitrous system has to be installed and then slowly jetted up along with retarding/advancing the timing as is dependant on the car. The best way to do this is on a dyno, however the seat of your pants will work on smaller shots as long as you monitor the motor for detonation or knock.

I do know my stuff. I wrote the the little nitrous FAQ in the tech section.

I think your confusing a "spool up kit" with being directly used to spool up the turbo. The use of nitrous in a spool up kit is to produce added exhaust flow and added thermal energy which spins the turbo's exhaust vanes. This in turn gives you not only a boost in power from the nitrous but a decrease in lag time.

BTW... I welcome you to spray a compressed gas on a spinning turbine that is well over 200 degrees. Happen to know what happens to thin steel when it is heated and cooled rapidly?

So how does the spool kit work if you cant spray before the turbo?

[godspeed]

im not saying you don't know what you are talking about, and i jumped the gun a little there, I just like honda's, i have had 4 and think they are good cars, as for the mags yeah there is a bunch of bs in them, but i just don't think its hondas fault for that.... but i guess there are a lot of people that are giving honda a bad name, while not the fastest car, i do think they have good engines, anyways back to your post, sorry to take it off track

[Aries]

It's alright, all is forgiven I just get testy late at night after bring under cars all day long.

As for how a spool up kit works...You place the nozzle 8 to 12 inches before the turbo. The nitrous sprays, cooling the air going into the turbo and basically doubling the effective cooling power of your intercooler.

[Cyberkreig]

You could just mount a pipe-loop to your IC... That'll cool your intake charge, and you can still run any kind you want (DIRECT PORT!!)

:withstup

Dirrect port is the only way to spray

another option would be to run a tube from the turbo inlet down to the small duct under the left hand side of the bumper.Basically like a cold air intake would be, but routed to the other side. Problem is, there just isn't that much room in the engine bay...

[Cyberkreig]

:withstup

you are right.. what was i thinking? wet-kits are for b-series engines ..

But have you seen that plug-and-play intercooler loop Zex makes? I'll definatly be gettin one of those.

[Aries]

the Zex loop is much like the NX intercooler ring.NOS has one as well, I just can't think of what it is called...

[midnight brother]

The Zex loop to me is a big waste of money and Nitrous Oxide. I have read about successull setup of a "Co2 loop" on dsmtalk.com. It cools just as good as nitrous, and doesnt cost as much. If you have the nitrous oxide to waste then be my guest.

Aries you have more knowledge than me on nitrous, so i have a couple questions.1. would the nos "noszle" system be better than a standard zex kit.2. i have read of tiburon beta engines in puerto rico who can run a progressive nitrous setup where they can handle 125shot safely, but not standard zex / blah shots of like 75+. are there any good progressive setups you can recommend out of the brands out there?

[Cyberkreig]

I would agree about the loop if you were only using the nitrous to cool the intake.. but if you are already putting in a nitrous system, a branchline and an the NX N-ter Cooler would be a 10 minute addon..

this post made me go back and read over the websites (NOS, NX, ZEX) The NOS systems seem to be a notch above. But i'd love to hear what Aries has to say..

The NOS noszle system is actually better than the Zex kit in a couple of ways. Zex is computer controlled based on a sensor pulse from you TPS. Should your TPS malfunction, your motor could easily be toast. Zex is not nearly as upgradable as NOS. With zex you are literally forced to buy a second full kit to run a dual stage setup. With NOS you can simply expand your existing kit with a few lines and solonoids. No extra computer controller to buy.Also, ZEX and NOS both rate their shots at the flywheel not at the rear wheels like TNT and NX do.

As for progressive controllers...I am running a NOS progressive which is actually sold by Holley on my LT1 and loving it. I have tried the MSD, and it did work, however it was not as adjustable as I would have liked. The NOS progressive nitrous controller is definately a notch above.

On the Sharks (Tiburon means shark) you are talking about, the heads flow with a system very much like VVT. When they recieve a sudden large burst of nitrous they tend to have valve train control lockups causing the valves to all be open at the same time and detonate. On the progressive controller, the nitrous is released in a controlled and gradually increasing stream that gives the valvetrain time to switch to the 2nd set of valves in order to handle the increase in flow through the head.These beta motors are also rumored to ba capable of holding 500hp on a stock bottom end...

So when I'm ready to spend $$ you gonna help me pickout what i need Aries?

So when I'm ready to spend $$ you gonna help me pickout what i need Aries?

sure.I'm always happy to help out anyone that asks

Just let me know what kind of numbers you want to run, and what thwe budget is

[gibbo80]

Back to the original question, i think JWT makes some computer controlled nitrous systems and are supposed to be some of the safest (some people on altimas.net run it). Another when it comes to NOS vs Zex I am pretty sure nos measures the shot at the wheels and zex does it at the fly that is important if true. I also heard that zex doesnt run fuel selenoids to make sure your getting gas plus your nitrous. I know NX does this im sure NOS does to.

[Aries]

both NOS and Zex measure at the flywheel.

The JWT chip is crap. Simply crap. They retard the timing using the chip by 14 degrees at launch and 18 degrees before redline. Their programming is waht stops it from being good. And they only do it to coverthemselves from lawsuits due to blown motors using their chip.

[godspeed]

my cous...works for forced proformace and he always tells me that nx kit is better than the nos, it will get you more whp

[Cyberkreig]

Which is more important to you WHP or flexibility and engine safety? Which makes a kit better?

[Aries]

which would you rather have...advice from someone who's been doing nitrous installs for years, driven a sponsored nitrous car, and owns a performance shop specializing in Nissans... Or a 4 man turbo shop that builds DSMs?

Forced Performance used to be based out of Kyle, and I know most of the guys there. They are dealers for NX, and that is why they push it. (BTW, Who is your cousin over there?)

Personally, I don't like any one kit. I like to buy them in pieces and use the best of every kit to make the most power in a safe way.

[Structure240sx]

i was goin to mention that jwt makes an ECU program for nitrous b/c SRds14 im pretty sure runs a jwt ecu. but after hearing what aires said i would stay away.
