New to Tuning, Would appreciate any help possible.

I finally got a car which I can actually say I own. It's a 2003 Mitsubishi Eclipse GTS, that was previously a show-car with no performance mod's. My friend used it as his daily driver until it was in an accident, but it was mostly cosmetic damage.

The car is basically stock. There are a few changes that he made for aesthetics, but everything else is factory.

Now I like driving fast, and I decided that I wanted to experiment a little with this car. I have only the slightest idea, mechanically about cars.

Is there anything you would recommend to help me get started? I'm looking for ways to increase the performance, but I want to be able to do most on my own.

Any specific parts I should look for, any websites or books to teach tuning/modding, or any help at all would be greatly appreciated!  

There is lots of mods you can do such as cold air or short ram intake, oil filter, or headers. Here's something to help:

^Thanks for posting that Wolf.

Treyzian, if that guide helps you please post on it.  Also, get the Chilton manual for your car, that will help you out with a lot of the DIY stuff.  Also, get yourself a good set of tools. Craftsman is a good tool company.
