I've also been thinking that one could design a radial engine that uses
off-the-shelf VW cylinders, pistons and maybe even scat heads. As with
most such ideas, someone else has already tried it:

How about using inline 4 Cyl, one liter, liquid cooled motorcycle cylinder
blocks - say, from a Kawasaki GL1000. Mount 9 of them around a radial
crankcase that contains a planetary PSRU in the nose case. You would have a
36 cylinder, 9 liter replica of the Lycoming XR7755.


I think one or two companies have made modular engines wherein
each module is a two cylinder boxer and you bolt them together
to make a flat four or six. If you bolted the second module on
at a right angle you'd have a pseudo-radial.
