This Toyota 86 has a 3.0L flat-six EZ30 motor sourced from a Legacy 3.0R replacing the factory installed FA20. The motor is putting 250 horsepower to the rear wheels but the owner is hoping to get around 313 horsepower. It would seem the 86/FR-S/BR-Z engine bay can handle many different engine platforms. We have seen a 2JZ, LS1, 2AZ-FE, 2UR-GSE, EJ25, and now the EZ30.
Below is a video of the exhaust sound.
