Filed under: Aftermarket , Coupe , Performance , Scion , Subaru , Toyota Subaru may or may not produce an STI version of the BRZ . Things seem to go back and forth on the subject. But Subaru Tecnica International isn’t the only company with a history of tuning Subies. So does Cosworth , and now the British racing firm appears to be turning its attention to the BRZ and its Toyota- and Scion-badged siblings. For those unacquainted, Cosworth is more than your average tuning company. It’s a racing firm first and foremost, having made F1 engines under its own name as well as Ford’s (chief among them the all-conquering DFV 3.0-liter V8 of 1960s and 70s fame), not to mention engines for Indy, rally and even high-performance, road-going versions of the Ford Sierra , Chevy Vega and Mercedes 190E . The list goes on and on, but you get the point. Now withdrawing from Formula One , Cosworth is focusing its attention on tuning road cars again with the launch of the Cosworth Power Package line, the first of which will focus on the Toyota GT86 (aka Scion FR-S ) and Subaru BRZ. We don’t know just yet what will be included in the packaged dubbed FA-20, but from the video teaser below, it seems there’ll be upgrades to the exhaust, suspension, aero and – if we’re lucky – maybe a super- or turbocharger for the 2.0-liter flat-four engine. We’ll have to wait and see, but we get the feeling that with Cosworth on the job, it’ll be worth the wait.
