Engine Hacks: Build a turbojet from junkyard parts

Turbo chargers from cars are readily available and easily modified, so why not modify a turbo into a jet engine?

While [Mike]‘s junkyard jet made the rounds on the Internet over a decade ago, the theory behind the homebrew turbojet is still sound. After pulling a turbo out of a 1983 Nissan Pulsar, [Mike] built a combustion chamber out of 2-inch pipe fittings. The propane fuel is ignited with a simple motorcycle spark plug and produces a hot and powerful blast of air twenty feet from the exhaust.

We suppose [Mike] wasn’t satisfied with such a puny engine made out of junk, so he decided to step it up a notch and improve his engine. After some development, [Mike] managed to build another jet out of a larger turbo that doesn’t require a constant spark. The newer engine produces ‘hurricane force wind’ 10 feet from the exhaust. We’re not sure how much thrust that translates into, but we’re a little surprised this engine hasn’t been mounted to a go-kart yet.

Check out the walk through and demo of the junkyard jet after the break.
