Bill, I'd say buy everything from online vendors. If you do your research, you'll save a LOT of money. If and when you do buy new parts, I'll gladly help you install them!
PICTURES, PICTURES! Turbos, rims, and WRXs!
We just installed a new turbo on whap's car friday night! We also did my uppipe install a couple of weeks ago.
Just keep us updated. And I'm willing to put you in the right direction for what you want to purchase. I'm pretty good at finding good prices on stuff!
