There was no  manual transmission 20B as far as I know.  Someone may have done a custom build for one though.  The 20B auto counterweight is unlike any of the 13B counterweights.
 
9.0 for CR on the 20B. (stock that is)
 
All engines need the 86 - 91 RX-7 auto flexplate for use with the RD-1x geardrives.

manual trans flywheel and counterweight.  Having been twin-turbo'd in
its original life, I understand it would have 9.4:1 rotors (right?).
Does a 3 rotor use the same flex plate and counterweight as a 2 rotor?
Or would the counterweight have to be different??
