In 2012, Subaru will introduce two turbocharged variants of its latest-generation direct-injection four-cylinder boxer engine, including a 300-horsepower STI version.

The new FB engine architecture, first launched in the U.S. in normally aspirated guise in the 2011 Forester, will add boosted 1.6- and 2.0-liter variants next year.

Yet to be determined is whether the boosted version will find its way eventually into the new Subaru BRZ sport coupe. So far, Subaru is only talking about a normally aspirated version of the new 2.0-liter boxer engine for the BRZ, a variant of the FB architecture known as FA. The FA engine in the BRZ is understood to produce 200 hp and employ Toyota's D-4S direct- and port fuel-injection layout, though company officials would not confirm these widely held notions.

On the force-fed FB variants, the turbo is mounted beneath the engine, in contrast to the high-mount location typical of the turbo EJ-series engine still used in the U.S. The intercooler remains mounted directly above the engine.
