I can't get over how the engine "just fits" the 911 engine bay. It's almost like it was made for a V8. (flame suit on) I love my air cooled 911 but this is intriguing for many reasons.
I've hear rumours that the successor to the 997 may have a V8 out the back instead of a flat 8... I'll guess we'll see soon enough but if Porsche goes to a V8 then these conversions will be seen in an entirely new light
