Russian YouTubers have transformed a Subaru boxer engine into an industry-standard inline four-cylinder, using it to create a unique engine for their workshop. The project involved cutting the engine block in half, joining the two sides together, and rearranging the cylinder heads in line with each other. The unique engine was designed to distinguish itself from more common inline and V-layout engines due to its unique weight distribution, power delivery, and engine sound. The engineering challenges included the need for an extra Subaru engine to donate its crankcase and crankshaft parts for the new motor. The YouTube channel Garage 54 specializes in these unusual projects and experiments, which have previously included powering a Toyota 2JZ engine and powering a Lada with an engine made of 50 cordless drills.
