Dry Kit Questions...
Stick with the jets that come with your kit, or at least that style, as there are some diff ones out there.
Not knowing what year your car is, it's ahrd to determine what your max hit should be. A 125hp hit is doable but some considerations may be needed ie: injectors.
The kit I rec is the PRO Dry kit from Nitrous Direct, it's a little more than what you quoted, but a complete and quality based kit. It also includes Fuel Press Safety SW, NHRA Blow down kit and more, whereas the cheaper kits normally don't included these items. Also, dual stainless steel nozzles compared to the normal aluimin in most kits. Includes the 400hp Pro noid with a lifetime warranty, one of the best noids on the market. I can link you to a intro thread on this kit if you like. we also have the cheaper base kit, closer to your quote. let me know if you have more questions, you can pm me if you like. Iam sure the other vendors will give some more ideas. Good luck on your kit choice.
