I know this is such a noob question...forgive me.

I have a 94 civic lx sedan and i love it. Theres no way im getting rid of it. Just one thing, ITS SLOW. It is very slow. Sometimes its embarrassing when im at a red light and some old broken down car beats me off the line. The only thing i have done to it is a cold air intake and exhaust. Considering i am 17, I am willing to spend a good amount of money on this car, but not too much. I just want to know what would be the best item(s) to get in order to gain more hp and have a decent quick car. My friends tell me to get rid of it because there is no point but i dont listen. I love this car adn i know it has potential. Thanks for all the help.
