100 dry shot??
Take your time and read the sticky's, or call the vendors and tell them what your goals are if you want the "Quik" answer.
Either way its worth your time to research the issues and check the AFR/KR on a new nitrous setup.
Best Kit is subjective as well, but you can't go wrong with Dynotune, HSW or Nitrous Outlet who are the site nitrous vendors.

With a dry sytem tunning is alittle more complex but very doable. When you add your cam you will deffintly need to upgrade injectors. For now since your car is pratically stock you should be fine with a small dry shot. I would verify duty cycle on the injectors while tunning.
There are many systems to choose from.
Please take time to check out our products and feel free to ask us any questions you may have.
