Subaru BRZ Getting 230 HP Without Turbocharging
However, with the 2.0-liter boxer engine being so compact, and mounted very low, it is very difficult to fit an intercooler to it, according to autocar.co.uk - they could, however, fit one on top of the engine, like in the Impreza WRX.
Thus, Subaru will be launching a more powerful version of the BRZ next year, yet they will not use a turbocharger to boost its power. Instead, they will be taking an old-fashioned approach to tuning, fiddling with the engine mapping, intake, variable valve timing system, as well as the exhaust, to get a slight increase in horsepower and torque.
They apparently want to raise the total output by 20 to 30 hp, and the extra grunt will be kept in check by larger (and wider) 18-inch rims, larger brakes with four-piston calipers, as well as a subtle body kit and a hefty rear spoiler. Inside it will get sportier seats, as well as other sporty touches, to let owners know they are not sitting in the ‘base BRZ’.
Expected to be called the BRZ STi (or not), it will arrive in Japanese dealerships in the spring of 2013, with Europe and the US soon to follow. Expect it to cost at least €3,000 more than the regular model.
