As PA28181 says, you're getting your engine types mixed up Alex. An SEP with turbo differences training is just what it says - a single engine piston.
The turbo differences training is about turbocharging on that piston engine. Nothing to do with turbines, which are jet-prop engines.
.........the turbine is an integral part of the jet engine, whether pure jet, fan jet or jet-prop.
.........the turbocharger is an ancillary added to a piston engine, as on many cars, as an alternative to a supercharger. They are sometimes referred to as exhaust superchargers.
