I'm new to this, Here's my question can I use a 2.2 engine & transmission from a 99 Impreza Outback Sport to replace engine &trans in 02 Outback wagon 2.5 ? I've heard that 98 2.2 was last year that could be used. I would like to keep this engine & transmission together if possible (They are matched set with only 43,800 miles). What else would have to be swapped ( CPU,TCM) ? HELP!!!
