Sources from Subaru of America revealed of a turbo in development for the Subaru BRZ's 2.0-liter flat-four FA20 engine.
Compact in size, FA20′s square 86x86mm bore and stroke plus a trick D4S port and direct injection system allow the engine to produce 197-hp and 151 lb.-ft. of torque. No word on the turbo's engine output, its size, and its applications for the new powerplant yet, but we believe the addition of a turbo will make way for a standout BRZ STI in the future.
However, Subaru has not yet confirmed development on a turbocharged BRZ, but the anticipated release of a new Impreza WRX variant implicates a need for a turbo FA20 there as well.
