Of all the possible engines available in the Subaru Impreza range, one thing remained constant: they all had four cylinders. That's why we're filming this one. With a flat-six engine sourced from a Subaru SVX, and driveline, suspension, and interior parts sourced from a huge range of other Subaru's, this is one of the more interesting modified Subaru's we've seen. Amazingly enough, it works!
