He is in finland and he don't have a V8 available as I under stand, that is why he is talking some kind of 6!
When I think of car modders in Finland, I think crazy turbo. Not to keep getting on the German cars, but when I owned my 633csi, all the guys from Finland, since engines are sparse, and maybe also due to car regulations, were stroking their current motor and slapping a turbo on. correct me if I'm wrong on that part, it's been a while since I've read Fin turbo threads.
I agree, a new motor dual overhead cams sixteen valves fuel injection would be the way to go if a v8 wasn't available
