Dave you are bang on with the info I have, except for the precautions
required when starting a turbo when it has been sitting for a
long time. You
should remove the intake hose and spin the impellor in the
correct direction
and while it is spinning fire the engine for a few seconds. Watch Your
Fingers!!!! This insures the turbo knows which way to turn. :-).
I attach a
photo from copperstate you may enjoy.
