What would be involved replace a 2.5 AT with a 2.2 5MT motor . Taking 2.2MT motor from a 1992 Legacy into a 1998 Outback that has a 2.5AT.

Thanks

Year of the cars would help. These guys know them like the back of their hands.

Says in his original post he wants to put a '92 Legacy 2.2 into a '98 Outback.

Pretty easy to do over all. Pull the 2.5. Swap the 2.5 flexplate in place of the 2.2 flywheel.  Install the 2.2.

 

You'll either need to swap the 2.5 wiring, etc. over to the 2.2 intake manifold which should run fine but throw an EGR code. OR - the easier way would be to find an intake manifold from a 95-98 automatic 2.2 that is EGR equipped and bolt that to your 2.2 - there's an easy workaround to run a hose so there's no check engine light. Pick n pull is your friend.
