[mark]

Can the EJ22 engine (2.2L Legacy Engine) swap directly into a 97
Outback that previously had the EJ25 (2.5L Outback engine).

I can't give you an authoritative answer,
but I suspect not. The 2.5l engine has
camshaft sensors that might not match
signals from the 2.2l

I've been told only the 95 2.2 interchanges. Seems the 95 engine has the
dual port exhaust heads and something about an EGR port.

Hi Mark!

Outback that previously had the EJ25 (2.5L Outback engine).

It will physically fit, but there will be significant differences in
the wiring, emissions, and (I think) exhaust port configuration.
You'll probably want a "donor" car to facilitate the conversion. You
can probably find more than you ever wanted to know about this on the
usmb list <http://www.ultimatesubaru.net/forum/>, I'd start there.
