To quote Brendan (a good guy to ask questions if he hasn't already answered them) from a recent post (go back and look for a post called 'nitrous').

Which system are you geting, I recomend zex for easy install and safety, nothing special you need save for new plugs, get plugs 1-2 heat ranges colder, and NO PLATINUMS . start with a 55 shot and hit it @ 3000 rpm or more, you'll be fine. headers and exhaust will help more, read you plugs when you first use it to, as for fuel I changed the fuel pump, a regulator won't do squat if you can't give it the fuel.
