Welcome to CI...I'm Justin. Hope your enjoying your car!
A few things...
1) To learn what people are talking about on forums...I'd probably advise you to join up on Team-Integra as well. They have a ton of articles on the site submitted by really knowledgeable enthusiasts and should help you get familiar with the acronyms around here. (ie: SRI = short ram intake, etc)
2) To squeeze any real power out of your car, its going to take alot of time, planning, and money. You cant turn a car with just over 100hp at the crank into a monster with a few basic bolt ons. Sure you can invest in an intake and full exhaust system, and that might suit your needs...but to make ALOT of power your going to have to overhaul the internals, plan a build out in full (this includes suspension work, transmission work, etc...you can make all the engine power in the world but need a STRONG transmission to withstand that power and a GREAT suspension setup to be able to keep the power on the pavement), and most likely plan a weekend at the dyno for tuning.
3) Street racing is a pretty sore subject with some people. Some don't mind talking about it....others will frown at you. People get seriously hurt and destroy other's lives when they can't keep racing off public streets. You'll find that people that are really into these cars prefer to take it to a track and actually get real results as to what their car can do...rather than if you can beat some other shmuck out on the street. Sure everyone has a little fun sometimes...but please be SAFE about it and don't jeopardize any one else's lives, property, etc. I really hate seeing threads about people crashing their cars and/or losing their lives in a racing accident.
You sound fairly young...16-18? Just enjoy having the freedom that comes with having an Integra and get used to the car. Modding and racing will come in time. Most kids immediately want to hop on the fast track without ever learning the basics of their car at normal operating speeds. The best thing you can do is get to know your car and learn what it does under certain circumstances before you get into a situation where your going to fast and have to guess.
There are alot of good people on this board that don't mind helping out with information...so definitely take advantage of that (but at the same time doing your own research as well!!!).
