you are ignorant by saying fuck nitrous. people are so stupid in believing what they hear. i sprayed 4 bottles on my car which is like nothing and i NEVER had a problem. i have a couple of friends that have been through 15+ bottles and the motors runs like new. honda motors fucking LOVE nitrous. to use the 59300 safely you should upgrade your springs/retainers...but i've heard of a few people running it on a stock valvetrain. if you dont want to spend the money on the valvetrain get the 59100 cam, not as aggressive but still makes better power than the stock cam does. and no, you do not need to use nitrous to make the cam "work properly".
