i myself have a 2.5 rs, i have minor bolt ons, exhaust, short ram intake, and a lightened pulley, and wondering what else i can do keeping it n/a. Also i have a question that someone with some extended knowledge in subarus could answer. I was wondering if you could put a block from one of the subaru suv's or the legacy into a impreza to make it a 3.0l or higher, just like how they do with some civics they put the b20 (crv) block into it to make it a 2.0l. anyway could this be done to make give the impreza more potential to be a fast n/a car. and please save your time if you are just going to give me a rough time for wanting a n/a subaru. thanks
