Several years ago EDM Speed Projects built Vini the Mini with a naturally aspirated 4.0 L BMW S65 V8 and M-DCT seven-speed transmission. More recently the company built a Subaru BRZ to compete in time attack. Instead of using the factory 2.0 L flat-four, they swapped in a 3.6 L Subaru EZ36 flat-six. Unfortunately that engine broke and it was replaced by a 3.0 L EZ30 flat-six. The car has raced at several tracks including Silverstone, Donington, and Brands Hatch. Listen to the flat-six sounds in the videos below.
