I gotta know...
Which NOS system does everyone use? I want to put one on my 87na!
How much am I looking at?
Or would installing a supercharger be more economical? Either way I will be adding a lot of power!

Just spouting some information that you may or may not have any REAL knowedge about isn't helpfull to anybody.
Personally, I don't know much about the practical application of NOS in rotary engines but I'd bet my boots that a car in good running order with a properly tuned NOS/fuel system would have no reliabilitiy problems.
Sure, if you toss a whole bottle of NOS into the intake and go for it, you'll kill your motor but....hell, JUST running ANY engine will kill it eventually, right?

Nitrous will be cheaper to install, but you will blow your engine soon unless it is very tight. Superchargers from Atkins Rotary (sorry dont know web sight) are like $2,000.
Nos kit-600 dollars
Fire extigusiher-50 dollars

depending on the shot you want to go with, you might need a new driveshaft. basically a 40-60 direct port injection or plate kit would be all you need to get a really big boost. the kit costs like 600 dollars and isnt that hard to install. when you get nitrous, you HAVE to get new fuel pumps. and when you use nitrous, you need to open the airways more because the rotary engine doesnt get a lot of air into it. think about it, the general piston uses 180 degrees when it is working, and the rotary uses 270 degrees so of course there is gonna be less air space in the rotary engine. so you need to get a cone intake of some sort and maybe get a hood scoop to be safe. if you get nitrous, you must use 92+ octane gas or racing fuel or airplane fuel.

But unfortantly many people who mod their cars forget even the basics of making sure the car is running in good condition first. the second rule of rotary, should be That the car is tuned properly and running right before you change anything.
I can't tell you the number of people that post about a blown motor after they increase boost, or add on a better exhaust, or any number of other things, and yet never checked to see if the spark plugs or spark plug cable have more than 60k miles on them and need replaceing. Or haven't cleaned out their gas tank in 100k miles, or never changed their brake and clutch fluid every 30k miles.
This is why the old wives tales that NOS will blow a motor comes from. Yes, it will help you blow your motor, if you or the previous owners have not maintained the car properly.

To the point now. I ran all the way up to a 150 shot in my 86 N/A. I had a carburetor conversion and complete exhaust, but it can easily be done to a fuel injected motor(i ran mine at that level before converting to carb). If you go that high you will need to get more fuel to the engine as well as retard your timing(this is only for hits from the bottle over 125HP), but with any nitrous kit on a 7, you need to have a header and some free flow exhaust. My kit was the Nitrous Express Import EFI kit(excellent). I have also heard nothing but praise for the new Edelbrock systems, which are technically superior and are the absolute safest in every aspect. The edelbrock system has a piggyback computer that goes inline with the ECU and determines if you are running rich or lean, it then uses this information to determine how much fuel to add to the nitrous/fuel mixture before it FOGs. This in turn makes it nearly impossible to lean out when you are on the squeeze so no worries about detonation. I am buying this kit as soon as I recover from Christmas. But I will leave you with 2 rules to go by. Before you use your Nitrous, make sure you have the following:
1. an Air/fuel ratio gauge
2. Free flowing exhaust
I cant count how many bottle fills I went through on my Rex, I had my nitrous kit on my 7 for 25,000 miles and I would hit the bottle at least 3-4 times a week. Sold the car, and the bottle went with it.

and just to clarify one other thing on the subject. Like I stated in the above post, you will not need more fuel until you start jetting your Nitrous system to 125 shot or more. I am assuming that you are planning on staying at or well below the 100hp mark, which means you will have a simple bolt in install of your nitrous kit, meaning
1. NO you will not need a new fuel pump
2. You will not need to add more fuel
3. at these small levels of nitrous you suffer a VERY MINIMAL risk to damaging your engine
4. That supercharger on your N/A engine will leave you stranded long before the throttle in the bottle
If you have any questions you can PM me or give FC3S.org a visit, shoot Dave an email, he has experience on this subject as well.

also, how are you going to tell me that you DO NOT need new fuel pumps? the stock fuel pumps on the RX-7 may not be adequate enough because of how old they are. since nitrous oxide flows more gas, faster, through the pumps the old stock pumps may not be able to take it. i would be safe and buy a new fuel pump.

http://www.fc3s.org has a few Nitrous Oxide writeups, for both wet and dry systems. Good place to go for 13B N2O questions. Well some.

What I will do...
If buying a new fuel pump can only help the car and not hurt it, then I will buy one just to be on the safe side. I have advanced my timing some (about 3 deg) but I can reset that easily.
I need to do a little research of my own on fc3s.org i guess. Wish me luck!

go to www.nosnitrous.com and then go to nitrous, then plate kits, then 40-60 adjustable. it will tell you what you need.
