    Rumorpile: Three Different Power Boosts In Play For The Toyota GT86

    Peeking into the Scion FR-S and Toyota GT86 rumorpile, we have a number of stories talking about more power via two different ways; turbocharging and using a hybrid system. Add a third option onto that list. Chief engineer of the GT86 family, Tetsuya Tada told Drive.com.au that they are exploring of using a larger displacement boxer-four engine. More interesting is that Tada said the company is testing all three.

    "I hope to make an engine upgrade at least one time with this car. We [have] already tried all possibilities and there are several types of 86 prototypes at the Toyota proving ground now; one is a turbocharger, one is bigger displacement and [the other is a] special hybrid system," said Tada.

    Tada declined to give any details about the larger engine, but insiders say the engine is likely a 2.5L flat-four with 254 horsepower, a noticeable increase over the standard 200 horsepower of the current 2.0L. This option has two advantages over the turbo and hybrid plans; cost-effective and maintains the lightweight-ness of the vehicle.

    Go with the FB25 2.5L boxer (from the 2012 Forrester/Legacy) and use an Eaton TVS R1050 supercharger -- preferably with air-to-water aftercooling. The combination should be good for about 300hp with a like amount of torque peaking at about 3000 rpm. Boost will be about 17 psi which is a little on the high side, but not any higher than was used in cars like say the C32 AMG.

    That's enough for a FT86, there will be zero turbo lag and the car will feel as connected as with a large displacement NA engine.
