So, for all you folks that know more about heat shielding material than I do, what should I be looking at, and would you think this material would be suitable for wrapping the turbo itself?  

 

Thanks for any suggestions.

Rusty, since you are mainly concerned with radiant heat, you might consider some heavy gauge aluminum foil.  I've seen many turbos with that, but only in automobiles.
