What you are looking at is likely a first even for the aftermarket automotive arena. It is a Subaru powered Porsche 917/10 replica–and it is available. I have met many, many gearheads over the years and there are many who are fans of both Subaru and Porsche, so molding the two together to create a beast does make sense in a strange way.
Who would have thunk it? This guy fused two Subaru flat sixes to amass a flat twelve engine. Next, he placed it into a replica of the 1971 Porsche 917/10. Yep.
