Wade, Mark..  Thanks very much for your imput!  I'm very seriously looking
at the 20B engine to power my a/c. I've come from a farm, autobody/mech.
shop and now work as a mechanical draftsman so I'm not the least bit scared
of building an engine.. infact I think I'd rather do it that way so I know
what it looked like when it went in.[Plus I can get most of my parts at near
wholesale through my Father at his shop  <---- That always helps w/ the
costs right??  ;-) ]   I've also got an Uncle who built Turbo 13b Rx-7 for
my Cousin[ he's 14 and his dad built him a..!!  ] Anyway theres lots of
experiance to pull from if I need it so.. to make a long story short.. I'd
like to buy just a core and build my 20B.  Does anyone know if its alot more
money to build a 20B from 13B parts? Anyone on here ever done it?  Can
anyone put me in touch w/ anyone else who has?

I've borrowed a copy of the Tracy's old newsletters [Thanks VERY much Perry
!!]  I'm going to buy both his book and my own copy of the newsletters!
Some very valuable stuff.  I'm at a lucky stage right  now as I can totally
configure my engine install to suite my airframe, or rather build the
airframe around the engine. But I do need to decide what engine its going to
be.

Thanks again guys for the help!
