<VV> Turbo ID, --wasTurbo set up --was mileage

[NicolCS@aol.com]

As long as we are on the subject of turbos...  Has anyone put together an 
identification guide for the various turbines, housings, and impellers that are 
stock and common mods (i.e. E-flow)?  The castings are pretty obvious, what 
with the different exhaust gasket configurations (Early vs Late) and the presence 
of a part number on the impeller housings but I have several loose turbine 
and impeller wheels, one apparent E-flow turbo unit, and an NOS 
impeller/turbine/shaft unit all of which I'd like to identify.  Does anyone have a "spotter's 
guide" for these internal parts?  
TIA
