Default 04 engine into 02 wrx help please

Hi everyone, I just picked up my first wrx (2002) not to long ago. I loved them for a long time and finally found one at the right price and right time, but due to a timing belt slip I am in need of a new motor. I may still rebuild mine but in the mean time I found a 04 motor and just want to know whether it would work or not. So i guess my question is will a 2004 wrx motor swap into a 2002 wrx with out any problems I would still be using the 02 tranny, 02 ecu, ect... also i have a cobb ap (02-03) that why i dont want to change ecu's. This maybe a stupid question but like I said Im new to them and am not sure. I did sum research and haven't really found any differences that would be a problem but i could be wrong that's why im ask.

Thanks for the reply, I wasn't sure myself if it would all be compatible (wirer up and bolt in) I was pretty sure the motors didn't really change but was not sure about the 02 ecu and harness matching up with the 04 and if they all had the same # and same type of sensors
