What goes into the decision making when buying a new turbo - or upgrading the turbo in your truck with a new compressor wheel and cover? It's the least expensive route, but may not necessarily be the best way to go. Paul and Chris talk about turbos and various buying options with J.P., Calibrated's turbo shop overseer. He's taken apart dozens of turbos and has learned a few things about how they look after a few hundred thousand miles.
