I will look into Modifry's shift beeper and maybe search for some of his old posts. Gating nitrous is a great idea and in the past I have used the msd digital window switch to do it.
No one should really even think about using a dry shot, they are dangerous and dont make nearly as much power (its been proven that identical shots from wet and dry setups favored more power from the wet).

Dark, you are on the right track with your proposed set-up. If you want to play it safe so you can enjoy the S for some time to come then here is my suggestion:
Get a better fuel pump- the stock is good for stock power
engine management is not an must but highly recomended
dont spray much over a 75 shot
if you plan on spraying in lower gears then you need a better clutch & pressure plate
a progressive controller is great for taking the initial shock out of the drive train, will help the tranny and rear end last longer
Don't spray off the line- Your rear end will hate you!
Now I know people will tell you that so and so is spraying 150 all stock but they dont tell you his car wont last for more then 30 shots. And some people will say the progressive controllers are hard on the solenoids, and they are right, but what would you rather break in the middle of nowhere? A solenoid or a clutch? Or rear end?
Good luck with your quest in nitrous and spray safe!

thanks screaminyellow for that info, a 75 shot is less then what I was hoping for but understandable in the terms of what I am to expect later down the road.
red mx5, the one thing you need to consider about a 'small direct port setup' is that a: they may not make jets as small as you are looking for, and b: extremely small jets can clog much easier and the last thing you want is one of your fuel jets getting clogged. A good rule of thumb is to keep any direct port system spraying no less then a 100 shot across a 4 cylinder car.

I had a 50 shot wet zex kit. I was running it with NGK 2step colder spark plugs, zex window switch, bottle opener, and even the purge. It was pretty sick. Sprayed quite often, and never had a single problem. If you really want to get info on nitrous I would check out the mustang forum they do 200+ shots and they really know their shit when it comes to nitrous. When I did my research before I planned out my kit. I read that, to stay safe you should get at least 1step colder spark plugs, and if you are going over a 75shot get it dyno tuned. Also running a window switch is a must because if you hit the rev limiter it cuts the fuel to you engine so you spray just nitrous=BOOM, or you spray to early the nitrous builds up on your pistons and BOOM.

whatever you do, have the n2o turned off when shifting or at the top of the rev band, i saw a couple of hidden n2o setup before, the drilled the manifold from the bottom and hide the sneaky pete in the hatch(civic btw). the throttle plate thing is so is ragged to be out of sight

I know the AEM EMS has an entire parameter "page" just for nitrous. If your injectors are sized correctly, you can safely run a direct port dry shot system, and have your AEM EMS nitrious setup increase the injector duty cycle on your injectors to keep the fuel flow where it needs to be, as well as all the timing control needed to keep things intact. If I didn't autocross my car, I would be all over a nitrous setup, but you're not even allowed to bring a bottle to any of those events...
It's too bad, a direct port setup on ITB's would look

One guy locally is running a 150 shot along with a Vortech SC. However, he has fully built internals. I am also looking to do a nitrous setup, but I'm still debating how I want to run it. Let me know your results. Thanks.
