How would one go about Raising a rotary's compression ratio?
Is there anyone out there casting / machining rotors? Or do
all rotors come
from Mazda?

All come from Mazda as far as I know. Not easy to cast but it
is possible if enough people wanted them. 10:1 is about as
high as you want to go due to octane limitations.

Hrmmm,,,
I would like to get between 18 and 24:1 compression, so I can play with direct
injection of
jet A using a common rail pressureized electronically triggered diesel fuel
injectors.
Just for shop testing and runup, It does not have to be airworthy (yet)

Not possible with the Mazda dimensions. Rolls Royce tried it
with two Wankels in series with no positive results. These picts are of
a mock up of the RR engine I took in Hockenheim museum and not real
engine. The third picture appears to be the real engine.

"The roll Royce Wankel diesel engine R6. Chamber volume of the first
stage 3250 ccm, chamber volume of the second stage 1265 ccm. Since
one recognized early that the Dieselverfahren could be carried out
only heavily with a unit, one built group engines with roll Royce.
The R6 developed 1972 and brought an achievement of 350PS with
4500 Upm. The consumption minimum was with 2500-3500 Upm with
220g/kWh (161g/PSh). The runners were oil-cooled, the chambers
water-cooled."
