I donâ??t know where I got these drawing of the 13b engine dimensions. I
was going to build me a block dummy engine to size it up on my
firewall. My question is: Are there similar drawings available for a 20b?

Rick Irwin

I have some 3Ds but I don't recall the width of the special 20B
intermediate housing. Everything else is pretty much the same as
the 13B. I can send you dimension shortly but in the mean time you
can scale off this knowing all the other 13B dimensions.
For example the 13B rotor housings are 80 mm wide.

Paul Lamar ...No rotor no motor.

Paul,
I don't know if they show the engine by itself, but Mistral has some
nice dimensioned 20B drawings on their web site.
