I am starting to come to the realization that I am going to have to
re-do my motor mount (again).  In this picture, the turbo is only about
1/4 inch from the motor mount tube.  I had been hoping (probably
deluding) that I might be able to insulate the mount with a SS heat
shield and blast tube with perhaps some insulating wrap.  Does anyone
think I might be able to make this work?  How will I know if it is
getting too hot?  How far away do I need to move the mount?

Looks a bit too close to me too. That RTV hose will not take the kind of heat
that turbo will put out. And of course the nylon tie wrap will go away
faster than a speeding bullet :)

It will be less vibration if you rotate those rubber motor mounts 90 degrees.
What airplane is that Dave? RV4?

I also suggest you run the exhaust straight out the side to get rid of
as much heat as soon as possible.

Sorry to be such a pessimist.

Using the heat shield on the turbo should help.
One could tape the sensor of an electronic thermometer (like those sold
at Radio Shack) to the motor mount to find its temperature.
