Wildest Engine Swap Of All Time? Check Out This Porsche With A Boeing Turbine

In a post on rennlist, the seller, identified as Daniel5691, said that medical bills were forcing him to part with their unique creation. Daniel said that the car ran and drove, something that was proven by another YouTube video dated 14 years ago. That video included a comment from a user named Scott Hammons, who claimed he still owned the 928 as of a year ago.

Keeping the car ran counter to the advice Daniel gave in his rennlist post, which was to flip the car and pocket the proceeds. “I recommend fixing it up a little,” he wrote, “as you could potentially make a substantial profit!” He went on to add some details about the build, including the fact that the jet engine weighed less than the factory V8. He explained that the jet’s turbine drove a gear reducer/reverser that, in turn, drove the input shaft of the 928’s transmission, in effect acting like the torque converter on an automatic transmission. 

He added digital gauges for exhaust gas temperature, oil pressure, and oil temperature, although the latter two were not working properly at the time of sale. The car did have a working fuel gauge and speedometer, although the tachometer required some on-the-fly mental math to be useful.
