best bet is to get a turbo timer, (some late model Supra turbos have these
stock- different than the one im describing, tho) which runs engine for about
a minit or 2 after you turn off the key , running oil thru the turbocharger,
to prevent "coking"(shutting the car off after running high RPMs (super high
exhaust gas temps) and oil just sits in the turbocharger, and "cooks"...kind
of like clogging your arteries...which is the major cause of turbo failure...)
or get a "turbo oiler"  which is a cannister mounted in the engine
compartment, which feeds cool , stored oil thru the turbocharger after engine
is shutoff..
or you can do what i do, and everyone w/ a turbo charged car should do - i let
the car idle for at least 2 minutes prior to shutdown...to cool down the
turbo.
