In July, 2020, an extremely rare Type 47 Carrera motor was stolen from a Porsche shop in Holland. The value of this motor is 250,000 euros. Absolutely tragic. I have a question. Might it be possible with modern techniques such as CNC milling and 3d printing, for a Type 47 motor to be reborn with every part carefully reproduced? I asked this question to an expert, and he felt it was impossible. He told me that only it could be achieved is if an original set of molds for the engine block could be found. He told me that there are too many cavities that can not be reached with any CNC machine, even those with six or eight axis movement. I said, what about 3d printing a new mold? He said you would have to destroy a original block to accomplish this feat. But I suggested laser scanning an original block would be possible without harm. I hope we can discuss your thoughts on the matter. Many thanks and best wishes. -Scott Churchtype47

Original Post

In addition to Capricorn in Europe, Rainer Cooney at the Spyder Factory in New Hampshire is building new 4-cam engines complete with dual distributor ignition.   These engines are manufactured locally to original Porsche specs and drawings and are identical to original.  They can be ordered with original ignition or with hidden, crank-fired ignition (which makes them much more drive-able under 3000 rpm) but to the best of my knowledge, they cannot be ordered as stand-alone engines, only as part of the entire reproduced car (that may have changed over time, though).
