Subaru BRZ Engine gets Turbo, new Injection System

Subaru BRZ Engine gets Turbo, new Injection System

Rumors of a turbocharged Subaru BRZ are swirling around the internet, but would a turbo version even make sense?

Subaru is developing a turbocharged version of its 2.0-liter Boxer engine, one use of which could be the BRZ. That version will use a twin-scroll turbo system and Subaru-sourced straight direct-injection system rather than the Toyota built injection technology in both the FR-S and BRZ. Automotive News reports that the system, tuned for the BRZ, could make as much as 280 hp and 250 lb-ft of torque which would be a big jump over the naturally-aspirated engine’s 200 hp and 151 lb-ft.

Toyota already said it doesn’t plan to offer a turbocharged version of the FR-S. That combined with the fact that Subaru seems to be working independently on tweaking its engine would support the idea that this won’t mean a factory turbo FR-S is on the way. What about a BRZ?

Subaru spokesman Dominick Infante flatly denied the rumor, saying “we have no plans to offer a turbocharged BRZ.” Instead, he said the engine, as previously reported, is the powerplant being developed for the next WRX.

But with fans brandishing cash, it’s difficult to understand why the automaker would ignore such an eager market segment, when the engine will be ready to transplant. Or is it? Both the BRZ and FR-S are focused on well-balanced driving dynamics. Some worried that 200 hp wouldn’t be enough, but that idea proved to be generally unfounded.

Ramping the car’s power up by 80 hp could improve its straight line performance, but it may tamper with the car’s elegant handling.

Despite the denial, it seems likely that the engine will find its way into other cars. Subaru shared its WRX drivetrain with the Forester XT in the past and it seems logical that the engine would be shared, but Infante said those discussions haven’t begun yet.

Widely thought to preview the next Legacy, reports suggest the next WRX is actually being previewed in the company’s Advanced Tourer concept from the 2011 Tokyo Motor Show.
