NOS dry nitrous system with single flare jet.

I installed the NOS nitrous kit for imports on my 1996 Miata (JR headers/exhaust, RB intake, Holley fuel pump, 14 deg adv timing). I installed the nozzle just before the throttle body. After playing with the jetting, the difference in acceleration is substantial and was well worth the investment (about $500; my son and I installed it ourselves in about 3 hours).

My son has had a fair amount of experience with nitrous (on a car using for drag racing) and he was my consultant. The danger is hitting the engine with a shot of nitrous when running in a lean condition. To prevent this, we used a microswitch on the throttle. The nitrous (when armed with a dash mounted toggle switch) does not kick in until I am almost at wide-open throttle. I do not like to hit the bottle until about 3000 rpm. Once the nitrous kicks in (immediately), the difference is amazing. Not like the movies (e.g., Fast and Furious), but still impressive. I also run NOS Octane Booster and 92 octane pump gas. I have not had to retard the timing, but I would pull the plugs after installing and check to make sure the engine is not in a lean condition. I use a fairly cold NGK plug. Cost to refill a 10 lb bottle is about $40 in our area (central KY).

Difficult to remove without leaving damage

This is a nitrous system by NOS nitrous originally for a camaro I had but I instaled on my 91 miata when I sold the camaro. This nitrous system adds 250 hp

Not good for tires but think about it. a superlite car with 300+ hp. DO not put this on a miata that has not been designed for it. But if you have the money and the time DO IT!!!!
