SUBI1981 Posted September 2, 2016 Share Posted September 2, 2016 I have a 1998 legacy 2.5 DOHC needing a engine. I also have a 1999 forester SOHC. can the forester engine work in the legacy ? maybe a ecm swap with converters and o2's along with engine?

987687 Posted September 2, 2016 Share Posted September 2, 2016 Not easily, the only thing you could really do is use the forester bottom end between the outback heads. That's a generation split with no easy swap route. Quote Link to comment Share on other sites More sharing options...
wtdash Posted September 3, 2016 Share Posted September 3, 2016 (edited) Welcome, As noted above you're in between 'generations' Phase1 vs. Phase2. It's covered a LOT on here and most Subaru sites as it's one of the most asked questions. The easiest and best swap (that are also covered on here) is the EJ22 from a '95-'98 Impreza or Legacy. It's a 99% compatible swap. Read up on the minor gotchas. The 2.2 is a better engine, albeit 30hp/torque less powerful. But unless you haul a lot of stuff, tow or drive up into the Cascades often, it'll do. You REALLY don't want to try to get the '99 into the '98....just not worth the hassle.
