i love the idea of nitrous or turbo but alot of ppl do the same mistake and that is not preparing the motor for the extra load you can put a small shot of nitrous on it but its still hard on a basically stock motor. if you wanna spray or boost and really preform you need to build to handle the power. i like the other guy's idea of a cam thats always good and all of the ppl that ive ever been around that did serious motor modifications didnt do chips but instead had the computer tuned on the dyno. theres a guy here in greensboro nc named mark at Turbo Tune that does great work its not cheap but HE WILL find all the power that your motor can put out. theres probably a shop around you that can do dyno tuning. remember that the strongest part of your car is its weakest component so make it strong enough to hold what your gonna throw at it
