I want to do autocross, but I'm also going to drag with my friends and stuff at the track. And I espically don't have the money to get a turbo or supercharger, and I want some more power. Should I buy nitrous, or I could get new pullys which will give me like 40 more HP. Should I get something like that or are there other things that will give me kindof more power? And if I bought nitrous would that mess up my engine or anything?
