But mods like light weight pulley, bushings, and a n/a Cobb acessport (given your manual transmission) Will help you gain a few numbers, but the butt dyno should say more.
Honestly, there's not much you can do. Personally id keep the money and get a wrx, because if you are looking for bigger gains, turbo is practically the only option. You could get an Avo turbo kit which puts you at 3grand to put onto your 2.5i. From there who knows if it Will pass inspection or throw codes.
The Cobb website only offers this for their turbo models. Is it not even worth it then?
