OK...which flex plate should I look for to fit a 20B that came with 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??

Will a flex plate and counterweight from a 3rd gen 13b fit a 2nd gen 13b?  How much for a flex plate and counterweight?  Thanks for any help.

Joe,
   A 3rd gen counterweight and flex plate will fit 2nd gen 13B but the counterweight
will put the 2nd gen out of balance unless rotors and both counterweights  from the
3rd gen are installed also...........On another note if this engine is for an A/C using
Tracy's redrive you must use a 2nd gen flexplate........FWIW
