well hun, the kids here who have been kind enough not to flame you to purgatory and back have given you a lot of info. they're telling you what kinds of mods would be best suited for the car you're considering, and what to do if you're intent on going the nitrous route. probably most importantly, they're telling you to forget for a moment what you've seen in the movies, slooow down, and learn to understand and handle your car before you get involved in any of that. these are people who have a lot more experience than you do. can you take a hint?

oh, and by the way, the people who have encouraged you to check www.howstuffworks.com have probably given the most invaluable advice so far.
