Tim, almost forgot, If you had some piston exit the engine check the turbo impeller for damage. Any damage at all, [nicks, bent blades or chunks removed] and you will need to replace the impeller/shaft. If you don't the turbo will shake itself apart. Happen to me when I fryed a piston and some parts of the rings tried to get out thru the turbo, made a mess of things but caught it before the turbo was totally junk.
