I like this thread. I don't have any plans for a bigger turbo but my inlet pipe has a slice in it right at the turbo end and I've been looking at replacements. such a pita though with it being such a tight space. a wrx pump/resy would be a smart idea. also I don't know whether the pumps would be different but it looks like the regular 2002+ impreza's p/s system is the same as the wrx. so if that widens availability of used parts, then it'll be that much easier to find
