I know this has probaly been discussed before, but is there really a difference between NOS's setup and the one NX offers. Right now I'm leaning toward the NX setup with the GenX kit, is this a good choice for my 99 GS? I'm deep into the show scene and need a system that will look good as well as perform good. I don't want the all the time power that a turbo provides, just a little kick every once in a while or during those 1 time a month trips to the track so I won't be spraying but a small amount. Anyone with some info, let me know

There's no difference between the two. I've found that the NOS system is cheaper and it's easier to find NOS brand parts & add-ons. Ofcoarse, most of the parts are interchangable between the two systems.

Before installing nitrous on that car, you need to learn everything you can about it so that you know exactly what is going on and could descibe it to a class full of people. :) I just don't want to see you fuck up your car and it sounds like you're a but confused. Good Luck.
