the base impreza has no room for improvement, you obviously came from hondas which is why
1. you bought a base impreza
2. you think you can just stick a turbo on it
3. want to put cams in it

some problems
1. the base impreza is not a car to modify, it would be a total waste of money
2. the engines are completely different, its not just a wrx engine without a turbo
3. we have boxer engines, cams require removal of the engine because they are on the sides.
