So... I have tried to compile the information I need to replace my '99 Outback' EJ25D with an earlier EJ22, but there is so much *conflicting* information this is quickly getting ugly.
I have read somewhere else that I can remove the EJ25D and throw in the EJ22 just carrying over the EJ25D intake manifold and flexplate, and -depending on the year of the 2.2- using the original or the donor's Y pipe. Now I'm reading that some 2.2 don't have the EGR pipe, that I may need to replace the ECU, that the starter motor may not work, etc. So, what's the real story? This thread talks about an EJ25D to EJ22 swap and paints things very nice, but I wonder if because of the MY ('99 vs '96) something may have changed.
I just want to replace the engine with one that works, but I don't want to mess with ECUs or mess too much with modifications. If anything, I like to get more MPG out of the swap (and keep using regular fuel). I hope it's not too much to ask...
BTW: WJM... if you see this could you let me know? I have a question regarding one of your posts, but I can't seem to be able to find how to send a PM
