While Toyota is believed to be planning a supercharged version of the engine for use in its 86 sports car (the twin of the Subaru coupe), it is unclear if Subaru's turbo engine will ever appear in the new coupe.
The report comes from the USA's Motor Trend magazine, which claims that a Subaru of America executive has confirmed the engine's existence, but would not divulge any power or performance figures.
In its regular naturally-aspirated form, the FA20 benefits from the addition of Toyota's D4S direct-injection technology to produce 147kW and 205Nm of torque.
With a turbocharger and the requisite tweaks, the engine could conceivably deliver 200kW and beyond. The current WRX offers 195kW, while the WRX STI leads the way with 221kW and 407Nm.
As for a debut for the new WRX, Subaru has confirmed only that it will separate the performance model from its Impreza roots, with the goal of taking the iconic Suby's handling and performance to all-new levels.
