Could a 7.3 EcoBoost turbocharger kit be far behind?

Why ? This is a TRUCK engine. Truckers (or the people who buy the trucks) want the "best bang for the buck" from initial purchase through maintenance with a long life.

Supercharging get instantaneous boost. Turbo, irregardless of how well it is done, still has some lag.

Direct injection does very little to improve power or fuel economy. The 5.0L "Coyote" engine now has 16 injectors, 8 direct, 8 port. Most of the time it operates on the 8 port injectors.
