I have a 2003 subaru WRX and am looking to do a engine swap with either another 2.0 or maybe the 2.5. I understand all the things that have to be done to go from the 2.0 to the 2.5 but I am just curious about what year motors, either 2.0 or 2.5, would bolt up in my 2003 wrx? Just a ball park idea or any help would be much appreciated. Thank you!!
