well I finally read all this shiznit and it was entertaining. It went from one question to totally off the wall...I got lost and got bored for a bit. Finally, my 2 cents... Nitrous is NOT bad for cars, that is if it is in small amounts. Also, no the end result of nitrous being filled and filled over and over makes it one of the more expensive mods that you can do. Sure its cheapest at first and definately the most bang for immediate buck...but then its more and more and more to get that same "bang".
(yes I know this whole thing is over and finished...but I wanted to say it anyway
