Holset HE200WG Turbocharger

A genuine Holset HE200WG turbo designed for fast spool, strong low-end response, and reliable performance on small to mid-displacement diesel engines. Its compact design and factory T3 turbine flange make it a bolt-on upgrade for OM617 and OM603 engines running stock or mild fueling. Ideal for daily-driven turbo builds that want quick boost without needing larger injectors or pump upgrades.

Unlike its HE221 counterpart, the HE200WG includes a backplate and its own actuator bracket, making installation simpler and cleaner on factory-style setups.
