Got that beast home then had to figure out how to unload it without hurting
the engine or my back (too cheap to rent an engine hoist for a 5 minute
lift).

Decided to "undress" it to get the weight down.  Found many interesting
things, not the least of which is a stock 20b has about 20 miles of
spaghetti all over the top of it!

Got down to removing the turbocharger assembly and about a quart of old
engine oil drained out when I parted the flange.  This doesn't seem right.
Could this be why somebody yanked the engine?

Also successfully removed all but one of the exhaust manifold studs while
just trying to remove the nuts (they all galled to the studs).  The last one
stayed in the block... cause I snapped it off.  Argh.  Guess that housing
will be going to the machine shop for a drill out & heli-coil job.  Good
thing I'm not in a hurry.

By eye-balling it, it would seem that an entire stock 20b will fit within
the cowl of the plane I'm hoping to one day build.  If so, and the weight is
acceptable, are there any compelling reasons to *not* stick with the stock
engine?  Turbo replacements, modified water pumps, manifolds, stuff like
that.

I can thing of a couple of good reason to not stick with the stock turbo's.
Heavy and they crack if they are anything like the third gen 13B turbos.

I've got the Turrentine tape (on 12b engines).  Where can I find some
repair/overhaul advice/directions/specs, etc. for 20b engines (preferably in
English... I never bothered to learn Japanese).

Manifold project:  the 2nd core box roughed out and started sanding.  2 more
to go, then I can start the main pattern.

Stock Mazda turbo manifold is in UPS ground. You should get it next Thursday
Tom.
