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?

first off, pulleys don't give you 40 horespower. You should build up your engine before you get Nitrous. Camshafts, header, exhaust, underdrive pulley, intake, lightened flywheel, racing clutch, etc.
