"Awesome" doesn't even begin to describe this miniature Porsche 911 engine, which just so happens to be fully functional. Building a miniature anything is a royal pain, but creating a tiny engine that actually works takes things to a whole other level. With today's technology just about anything is possible, but this engine was built 40 years ago using the original factory schematics. Oh did we mention that it was made entirely by hand?

The man behind this project is a Dutch Porsche driver and precision instrument maker, so it's safe to assume he knows his stuff. Turn up the volume and watch him crank the engine on his 1:3.2 scale model.
