i run the NX wet kit. It uses your stock fuel supply to add to the nitrous. No need for upgraded fuel pump/injectors. Get the RPM window switch wich keeps you from spraying befor or after the desired rpm (3000-6000 in most cases). Also get the GENX2 upgrade, it comes with the accessories you need to make it a little more safe like a bottle heater, pressure gauge, ect. You'll need one step colder plugs for a 100 shot, you wont need to retard your timing. I run a 150 shot with 2 step colder plugs and iv had 0 problems. I wouldent expect your stock clutch to last long though.
