Tunehouse, tuning company based in Sudney, Australia is one of the first tuning companies that has brought out details on what could be done to the eagerly awaited sports car. And it seems that Tunehouse is going the way of a complete engine change.
Details are vague, but it isn't very surprising. Tunehouse (who seem to have upgrade kits for just about every brand sold in Australia) intends to throw away the Subaru BRZ's (seen in stock form right above) normally aspirated 200 of so bhp 2.0liter flat-four and replace it with a 2.6liter Cosworth tuned Subaru flat-four that would be good for over 330bhp.
Going the way of the turbocharged engine makes the most sense if you wanted to make serious horsepower. The Cosworth powered engine would have more similarities with the Cosworth tuned Subaru WRX STI or the Litchfield Type 25 WRX STI
