Just bought a black 06 STi with 450 miles @ my local dealer.Will share pics soon. But until then I want to learn as much as possible I know everyone out there knows something I don't so feel free to tell me about it. What works? What Doesn't ? And Especially what parts are the best bang for my buck.Also any of those little tweaks that you've found to make free HP.

 

Cobb Accessport (Engine Management) and Turboback exhaust are usually the first two power modifications subie owners get.

Stiffer springs and larger sway bars are the first suspension pieces purchased. Buying all four of these components will make your car a blast to drive.

 

look up the "snorkus" mod. once you remove it, you'll be able to hear your turbo better, and wont end up buying a BOV*






*BOV's are bad for our cars unless you have a upgraded turbo.
