look at nitrousoutlet.com. I ran there stuff on my ram. There brand X stuff will support 200hp. I would run a direct port system, even though you say 200 is what you want to run. Nitrous is very adictive, and you will want more. Spend the money now and only buy it once. Instead of getting a plate and wanting more than what it will do and having to upgrade later. Remember that you need a fuel system that will support it as well. You could run a dedicated fuel system with a 1gal tank and keep race gas in it for when you use nitrous, that way the tank can just be used to run the motor. Unless you have a track only car. Then it's probably not that important.
