Can any one recomend a Nitrous oxide kit for my T2?.

I dont know much about the whole setup of the kit or what type (wet,dry Fogger etc) can anybody please help.

Thanks.

 

PM scathcart!

 

ok

 

Wet and NX. that's your simplest.

 

Why does it have to be NX?

 

There sure seems to be a lot of ambiguity when it comes to Nitrous and RX-7's. I think its time for an article of the "engine R&R" caliber... Look for it tomorrow.

 

I would agree with scathcart. Go with both wet and nx.

 

I didn't agree. Why the big push on NX? I personally run NOS. There's very little difference between NX and Holley, I don't understand the push for NX. In fact, Holley offers a lot more accessories and parts.

But I agree on wet, for the most part. (haven't worked with controlling a dry shot with a haltech.... could work well!)

 

I would watch out for NOS.
I saw this movie where a guy blew hits floor boards off when he hit the second stage. It was crazy. Then he told it to shut up and it worked and he almost beat this sweet *** red car which I think had a twin turbo b16. I think the movie was called The Fast and the Furious. It was a real life documentary of these crazy dudes.

 

I recommend NOS brand kits. They have been doing it longer than anyone else to my knowledge, and their procuts work well. I have a write-up for wet and dry systems on my site.

How-To's --> Engine --> NOS wet and NOS dry

The wet is indeed the better of the the two systems in a street application. It is safer if anything. I ran it for quite some time on our project 86 and never had any issues.

 

I have not experiene nitrous with rotary engine. But I do have some experience with Nissan KA engine and Ford V8. Nitrous are pretty much universal. As long as you have proper fuel delivery and correct igntion timing and correct plug heat range. It should be safe.

For starter, NX or NOS wet kit is very well known and safe. Personally I really don't think any of it is better than other.

Start off with small jet first, and play with it until you find your optimum setting. And DON'T BE GREEDY. (Dentonation is deadly)

For advance/safety control. There are a lot of aftermarket product that help you control using nitrous.
Jacob make Nitrous master Mind.. it control amount of nitrous and ignition timing base on the load/throttle postion of the engine.
Or, some cheaper one like MSD make the timing retard box, of course you also need to run the basis CD igntion box.

oh yes, stock rx7 fuel pump may not be enough for nitrous application. But correct me if I am wrong, since i am not sure on this one. Walbro 255lph is a good replacement, they run about $95-$125.

I hope that will help

 

ok, here's the deal.

I'm loaded to ****. I work 5-7 tomorrow, so I'll have some evening time to write during.

Sorry for the delay, but I can hardly walk....

 

ok i know all about nos for rx-7 wet is the simpleist but however its the WORST for rotory motors a dry system of 75 hp max is the best and safeist abd becarefull if u decide to use wet u will burn up uer seals

 

Right......

280 hp shots and its the worst way to go.... What the **** was I thinking?

Care to explain, or should I just trust your knowledge of nitrous used in rotary applications, considering you can't even spell rotary.

This post simply isn't true. Wet on a rotary is the way to go. 75 hp dry shots is running your fuel injectors at near their very limit. Sounds like a quick way to toast a motor.

 

Scathcart, What fuel pump are you running?

 

what about ZEX? i dunt think ZEX makes kit fer RX7 buts its a helluva lot better than pressing a button and hoping ur motor doesnt pop.

 

On a T2 don't go above a 75 shot. I would recommend only a 50 on it though. Compression w/boost/N2O your gonna detonate with any more. On a turbo application use any kit you want. Its almost irrelivent their all good kit. Any single fogger wet kit would work great. As for non turbo aplications up to a 75 shot I would recomend running dry as the motor provides more than adequite fuel compensation off of the stock injectors. Make sure its only used at WOT and you'll be fine. Wet or Dry there is always a bit of a risk. I have tried both and many different kits on different cars. I also run it on my FC. The WET gave me lag that the dry dosen't.

NOS5123 - Ask for the wet kit on the phone.. This is the RX-7 pn for the dry the wet is just an add on.

 

Okay, first off, go buy a book. I have the Nitrous Oxide for imports I belive it's from Cartech. I dont have the exact name, it is at home and I am at work. Got it from Barnes and Noble. Good book.


I would personally go with NOS or NX. ZEX would be fine if it was a non turbo. ZEX is a dry system and I would say use only a wet system on a turbo car.

You could go with a venom system. That is if you are willing to part with an arm and leg.

 

The "lag" you speak of means that you weren't properly jetted for your atmospheric conditions. Wet simply means you are injecting additional fuel from a seperate fuel solenoid with the N2O from it's seperate solenoid. You won't get a lag unless you are jetting too rich. When you shot dry, you were running the overall N2O mixture closer to 14.7 than when you were running wet. However, if anything in your fuel system is not up to par (i.e. - fuel pressure regulator, pump, clogged injectors), you will definately run lean and blow your motor. A properly jet wet system will make the same exact power as a properly jetted dry system. A wet system just provides you with a larger safety net, which is important for our rotaries. Why don't you look at these pages. They explain a little more.

i run a 75 shot of zex on my n/a and it does fine, i think its better because its simpler no wiring mess or stupid siliniods to screw with go zex and you wont regret it. they dont make a spicific kit for the rex but any car thats fuel injected can rum the zex kit. go to zex.com and look around and you will see the difference in the zex kit and all the others. ZEX IS BETTER!!!!

 

I recently aquired a zex kit and i am anxiously awaiting the car im going to put it in. I hope it is as nice of a system as everyone is saying. Ill post my experiences with it.

 

Better eh? lemme know when you've run a shot higher than 200 hp.... Wait a minute, Zex can't handle that.

For serious power, go either NOS or NX.

The FC fuel injection is sketchy enough without worrying about adding a product well-known to cause detonation.

 

A properly set up wet system gives no lag. You may wanna buy a purge valve.

As for not going above 75 horsepower without detonation, well, if you have it tuned properly, and are running a retard unit, go as high as the engine will support. I've run 200 hp for many bottles, but I built my fuel system and nitrous system to handle it.

NEVER run nitrous without retard. I'd guess that's the number one killer for engines using nitrous, as most kits don't provide any method to retard.

 

What degree retard for a 50 shot?

 

2 degrees
