Whenever the engine runs, the turbos spin, but not that much.  When the
engine is under light load such as cruising down the highway (or driving
around a parking lot, or a residential area) the turbo spins about as fast
as a ceiling fan, and doesn't generate any compression heat.  It's ok, for
the brief period of time until the oil pressure comes up.

On more recent cars, meaning after the mid-80s, (and often on modern
aftermarket turbo kits as well), the turbos are water-cooled and plumbed
into the engine cooling system.  This both allows the turbo to cool itself 
more efficiently, as well as preventing oil-coking related problems.  The 
Island kit is not of this type, this is just informational.

I'm not much of a fan of oil additives in general.  But an oil with a high 
zinc content will improve the wear under low-oil conditions.
