I have a lancer OZ 2002..... and was wondering if it will fit a 17 inch wheel base.... also wondering about what i should do outside of a turbo to add some horsepower... at an affordable range.... also... what type of wheels are good (in general) please help... i have a week before schol starts and i need to start ordering parts!!!

yes, 17's will fit on a lancer.

the easiest part to add a few hp is an intake, you can get a decent one for about $100 and it adds 3-5 hp and gives you a noticable increase in throttle response, certainly won't make the car a world beater though.

Lots of wheels are good, avoid chrome though because it tends to crack and they're really heavy. Rota makes alot of wheels that are pretty affordable yet look classy and perform well.
