Greg, there are a number of reasons that I believe would indicate there are better ways to go.
 
1.  The two turbo Rx-7 assembly weights almost as much as the 13B engine block
2.  The twin turbo set up only provides benefit if you have it in a vehicle that needs to get from 0 to 60 mph in 3 seconds or less
3.   Their reliability history even in the auto where they are not providing boost continuously is not great.
4.  The Rx-7 single turbos have proven very unsuited for aircraft use and usually do not live long.  The twin turbo is unlikely to be much better in that usage (just my opinion)
 
A much better way for aircraft usage is to select a single turbo designed to provide power/boost at higher rpm.  Several folks have done so successfully - check out their installations.

Has anyone tried the dual turbo installation in their AC  Do they hold up?  I know they were using them in some racing applications, and I am trying (again) to determine which is the best way to go here.....
