A good gas turbine running in an optimized environment can exceed 60% 
efficiency.  A gas generator made from a turbocharger is not 
optimized for efficiency, but is optimized for ease of building.  The 
gas generator (turbocharger) does not provide mechanical power 
output, you need another turbine for that running from the output of 
the gas generator.

Take a good look at the difference between a jet engine and a turbine 
powerplant, they are VERY different.
