Engine/Power - non turbo (All non turbo Imprezas) Who needs a turbo when you have 2500cc? Cams, intakes, exhausts, etc. The 2.2L and 1.8L Subies are cool too.

it wouldnt be worth it, you would LOSE hp because it would lower the comp ratio, the engine wouldnt be able to utilize the ACVS. and n/a cams are usually a tad more aggressive then turbo ones, so either way it wouldnt be a HP increase even if the sti was SOHC and it worked on your car

first of all, its 05. the 05 rs cobb cams don't even work in the 06 so why would the sti cams? Also, i'm not so sure about the statement that sti's are DOHC, but who knows i'm only a 2.5i guy.
