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.
Generally u shouldnt need to go over 3000rpm for normal driving, but it is a 1.8L so u might need to rev more to get it moving. Its not really straining the engine, but your just wasting more fuel.
