Plenty of places to read about this car.
On these different sites the car is sneaking up on a million page views around the world.
This is probably one of the most documented 912's in the world.
This is the first 912 in the world to have this engine type installed 2010ish.

A very cool article about Porsche almost putting a 4 cylinder 2CAM4 engine in the 912. The article is from the Netherlands. If you go to the back of the article you'll find an English translation.
