From the web site Wayne has listed up there, it looks like the Forester is going to get a tweaked version of the 2.5L Turbo engine. This engine is currently available in the Forester line, as of the 2003 model line I believe. The stats for the standard 2.5 turbo are 210 hp @ 5600 rpm and 235 lb-ft torque @ 3600 rpm. Not all that bad really for a boosted four banger.
