The Subaru BRZ 2.0-liter SUBARU BOXER engine receives several internal updates for friction reduction including new valves, camshaft and cylinder heads. Accompanied with a new aluminum intake manifold and redesigned exhaust manifold for increased air flow, the engine output in models with the 6-speed manual transmission is increased to 205-hp and 156 lb-ft of torque. Also, a lower final drive ratio from 4.1 to 4.3:1, paired with the standard Torsen® limited-slip differential, improves acceleration on models with manual transmission.
