I could not load that dxf.

Yes I know. Way back in the early days a guy by the
name of Lou Ross put a Mazda rotary in a Mooney.
At the time the Mazda had a distributor that stuck
up several inches higher than the engine so Lou rotated the
the engine 90 degrees to get it under the cowl. He had
no other choice.

Since that time the crank angle sensor has been lowered and
there is now no height advantage to rotating the engine.

I am a great believer in the engineers
that designed the Mazda engine oil drain back system
and they had their reasons for designing the oil drain back
system the way it is. The other area that could be a problem
is the main bearing drain backs.

It is not nice to mess with mother gravity :)
