2013 Subaru BRZ by Accelerated Performance

We cannot say that no one has boosted a Subaru BRZ up until now, as we really don’t know if someone may have already done it and just not plastered it all over the Interwebz yet. That said, we can at least now say that there is officially a turbocharged BRZ running the streets. Its builder is Toledo, Ohio-based Accelerated Performance.

These guys and gals fitted a custom-built turbo onto the intake of the 200-horsepower (161 wheel horsepower) 2.0-liter 4-banger and netted some decent results. After running it on a dyno, they found that the boost netted the BRZ a cool 54.5 horsepower.

Many of you are probably wondering why in the world only 54.5 horsepower, as a turbo is typically good for 100, or more, ponies. Well, the BRZ boasts a 12.5-to-1 compression ratio and Accelerated Performance calculated that with such high compression, they could only run about 4 psi of boost – roughly 5 psi less than most aftermarket turbo cars push out.

Soon enough someone will tune the ECU a little more and throw in a much-needed set of low compression rings on the FA20 engine. Get that compression ratio down to about 8.5-to-1 and you can safely run 9 to 12 psi of boost through the engine without issue. That would get the BRZ near the 250- to 300-wheel-horsepower mark.

Maybe once people really start throwing turbos on the BRZ and have relative success with it, Subaru will finally add a BRZ Turbo to the mix. There have been rumors of a factory-turbocharged BRZ in the works, but nothing confirmed yet. For now, we just have to rely on savvy modifiers.
