Parts for 2002 ES???

I'm kinda new to this whole "making your car 50 times better than what you bought" thing, so I haven't a clue on where I can get parts for my new 2002 Lancer ES. Someone please let me know. Thanks

if you find out let me know, i have a 2002 oz rally edition, and i want to go really fast. i want to spank honda civics, i hate those damn rice burners. there pretty though, yet i still wanna beat them.:smoka:
