I understand you're trying to cut some corners and get a system for cheap. When you said you'd have to buy the adapter and jets I was only a little concerned. Then you asked about mixing and matching brands and I just have to say stop. Nitrous is nothing to fool around with! If you really feel like you need to add nitrous (which I'm scared of to begin with) get a complete kit, from one company, specially designed for your car. The risk of blowing up your engine just isn't worth saving a couple hundred bucks.
