Thankz,

Josh

most people here dont like running no2 in a rotary..i cant see why a 50-75 shot can be used if tuned for.
With all the bolt ons including bigger injectors i cant see why I cant run a 50-75 shot...anyone want to chime in?

I think your dead on matty. I don't know if I'd want to install myself. Maybe when I get her tunned I'll drop one in.

I have my car fully tuned, almost nothing left, ($38,000 so far invested). I just think a 50-75 shot of zex wouldn't hurt especially because of the automatic shut off (overheating of the mainifold). PLus it would probably get me in the 9's posibly.

Nitrous Express (or NX) makes a universal single fogger wet system thats for all cars, and can be used for the FD. Not too sure about Zex, however, there system is trottle activated, which is less controlable and possibly more harmful for a sequential twin turbo FD. Nitrous is something very dangerous to mess around with, especially on a rotary, so Id do alot of thinking before using it.

Zex sucks ***!

Nitrous makes me nervous just because everything happens soo fast. Not saying you can't use it in a rotary, but with the stock turbos you can just crank up the boost a bit to get the same results. Then when you reach the 14 psi limit you can apply the Nitrous costs to a single T conversion. For a high hp N/A car, nitrous seems to be the way to go just because you don't need that much hp all the time. Just the times you want to have some fun.

RX-Racer

I don't want to go to a wet system only dry.

Zex So far is the best way to go!

GsrSol

If he's that close to the 9's I doubt he is still tt.

RX-Racer

I have a single turbo (greddy T-88) i need bottom end power until turbos spool up.

Crashunit

If your going to use Nitrous, why would you go dry?? Wet is the only way to go imo if your even thinking of using it. Zex is fairly a new company as well, so I would stick with either NX or NOS. Using the Nitrous to spoll up your single turbo is why most people like to look towards Nitrous, and if you have nothing else to do, then thats one avenue you could take I guess .

RX-Racer

I was also just thinking of putting a 25-50 shot in my intercooler sys to colden the air twice as much.

Why would you go wet over dry?

ttpowerd

Till what spools up? turbo(s)

I would not go nitrous unless you have a big bank account and enough experience to tune for it correctly.

RX-Racer

Yes, the turbos. (The launch)

Experience in nitrous is something i don't have but that is why I'm asking questions.

Why wouldn't you go nitrous?

Supposly the Zex kit is safe (has a shut off valve).

Also i have money to a point. But since im only 17 it's it sucks because mommy and daddy aren't giving me any money at all. Unlike every other teenager out there.

matty

i dont think what turbo u have should effect your decision on wether or not to use no2. I think fuel is the real issue.
I dont know squat about what is out there on the mkt for nos but i dont think i would like a sytem that sprays all the time based on throttle..i would prefer something that i control. I would only use it at the strip or if i am up against something on the hwy that has more rwhp. Or if i just want to show a friend what she got. All the bolt ons puts a 2800lb fd near 350 rwhp. That is more then enouigh for some spirited driving. I just want the extra power on tap if i need it.
The other issue is who knows how to or who is willing to tune it on a FD. KD is my tuner and a doubt he would say its a good idea for some reason.

RX-Racer

Well my fuel system is upgraded :

-Fuel regulator
-1300cc Primarry
-1300cc Secondary
-So i don't need a fuel rail
-Performance fuel pump
-And a Power Fc to control it

Crashunit

A "Wet" system introduces a homogenous mixture of nitrous and atomized fuel into the incoming air stream, thus providing a perfect air/fuel ratio for each. Which means a more consistant and stable amount of Nitrous flow then a "Dry" system would deliver. "Dry" also does not come with additional fuel pumps like a wet system would as well too. If you just want to spray your intercooler with Nitrous, NX also makes a kit that sprays your frount mount with nitrous as well. They supposedly made a 50 HP gain on a turbocharged civic with it.... but thats a honda were talking about .

Also as gay as the Fast and the Furious was, there Nitrous was delivered via switch activated, which gives you more control with when and where you need your nitrous, as opposed to having it always come on at open throttle or at a given RPM. Wow I actually refered to the Fast and the Furious for some automotive reference.......

RX-Racer

I can see how a manual activated nitrous kit would be better but it is for people who know how to use nitrous.
You must know how to use nitrous in order to run it
safe.

I don't know how. And i don't want to learn the hard way.

matty

whats to know..u push the button when u want more power.

Crashunit

Before anyone ask..... Yes I've blown my engine with Nitrous in the past.. so there....

Anywho..... 1300 cc injectors for primary and secondary is a good start for a single turbo FD, however, adding 2 additional fuel injectors, going "Wet", and getting tuned for the Nitrous can also helps you from blowing your engine sooner as well. When playing with Nitrous, not getting enough fuel is not an option.

RX-Racer

Its pushing at the right moment.

I heard if you don't do it at the right time you can do
serious damage to engine.

matty

u have 1300 primaries with a pfc..i thought people say not to upgrade the primaries with the pfc?
who does your tuniing?

RX-Racer

I do some of it and Sr Motorsports

Crashunit

What's "New Engine 2mm Heavy Duty seals"

Are they ceramic?? If so then cool, that helps too.... but the last thing I wanted to say was, read up and learn alittle bit more on what Nitrous does and how to use it. Your car does not run the exact same way all the time, and the condition you will be facing at the track will vary, so what if you launching your car and you already lost all your traction and pointed to the wall at say 3000 rpm and your Nitrous decides its time to kick in?? Id stick with the switch... but thats just me. And if you want to play safe with Nitrous, dont play with Nitrous..... One day it can make your car run wicked and the next run you blow your motor. boosting alone is already hard on the motor... injecting nitrous just makes it even worse.... Im not condoning it, just warning if your going to use it. Its like StErIodS.... fun till you lose your *****....
