Does sound interesting, and you might well be right that you could
run higher boost on the WX.

Problem remains where one could mount the KS? I've also seen references
to people installing KS on the WR engine, though I'm not familiar with
that (I'm guessing very similar to WX?).

The only real candidate I can see on the WX is, there's a boss area
near cyl #3, where the control pressure regulator is mounted. The upper
hole could possibly be drilled and tapped to a larger size (in theory -
not sure if it's something I'd want to try...).
