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.

UPDATE 09/08/2012: Accelerated Performance have taken their new Subaru BRZ Turbo Kit out for some testing, managing a world record quarter mile time of 11.3 seconds at a speed of 127.4 mph! Hit the jump for the video!

I appreciate their efforts on approaching customers easily. It’s for easy communications and purchasing that will benefit both parties.

I think it’s also beneficial for the buyers whom they will ease efforts on purchasing cars for the transactions can be made anywhere with the help of the internet. smiley

I mostly look at a car’s style first. This one would not probably pass on my taste if it elaborated its components more. The performance as stated is already good.

Cool. I guess I don’t have to wait for some cars to be posted on eBay, and other online selling sites. I just have to visit the BMW site and make my payment. How much time will it take for the shipping of the paid BMW models?

They can improve this car with its interior design because it seems common than other cars.

The ponies don’t really matter on this BRZ. In fact, they’ve made it just right, and I want to see its whole performance on video.

When will it be available in the public? It looks that they made the tuning just right.

Wow. It’s engine is really something. It’s not just an ordinary or anything like the others. I think because of this many people will get interest in this car.

They managed it very well to achieve that certain kind of numbers. It’s not surprising that on the test drive, the result is above satisfaction.

Definitely, someone will get down the ratio to 8.5 to 1. From that, BRZ can reach the 250-300HP.

That is not surprising to all, though the details and data show it’s really rocking that place. Nice engine sounds. smiley

Terribly good performance awaits the BRZ. I can’t wait to watch another video of it having a test drive.

Yeah I’m a bit confused on its ponies. It’s turbo then yet has an output of less than a hundred?

Justin......"and throw in a much-needed set of low compression rings on the FA20 engine."

Yeah that’s the ticket I love blow by......Pistons maybe?
