nitrous systems are a waste of f**king time and money period. If you want fast re-build your engine, remove and bolt on accessory performance parts, learn how to tune your prelude its not that hard for christ sake. if your getting beat its because you don't have the will and desire to win, dont blame the lude blame yourself. If you got the money to just sell your lude and go get something faster more power to you but dont come to CO without something like a Z06, GTO, because if you come into the wrong parts out here this prelude will surprise your ass, haha!!! but then again I got to keep up with all my buddies who drive DSM's, STI's, and EVO's so when there upgrading their turbo's I got to get more parts, and tune my lude. Thats just part of racing if you can't work with what you got than you won't make it on the streets being an all motor car, but I'm proud to say I rape stock evo's and dsm's better have a 16g turbo with some mild bolt ons or they will be in shock while im pulling on by them too. P.S. I love that feeling.
