EJ253 to EJ255/257 swap? So, I have a 2011 impreza hatchback with a EJ253 in it. My goal is to build this for rallycross but as a student my budget is limited. Should I build up my current EJ253 or swap to a 255 or 257. I've seen a lot of people say to just get a wrx but my current shell is actually in crazy good condition, I've taken care of it and any rust that is on it, so I'd rather not sell it. (PS This is my daily and will still be my daily)
