In the last days of the 2 stroke Detroit Diesels they used a turbo to feed the blower. If you run across a Detroit 6V92T or 8V92T then you've found one to look at. The blowers were a necessity on the Detroits to scavenge and recharge the cylinders and the turbos were added to boost power, unlike why we use a blower on a 4 cycle engine. GM began phasing out the 2 strokes in the early 90's and introducing 4 cycle Diesels that were more emissions and electronically compliant than the 53, 71, and 92 series engines.
BTW one of my all time favorite inlines is a 6N71 Detroit. You gotta love the scream!
