Technical Notes

The K03-2072GAA 4 82 turbocharger is a small-displacement unit often found in compact petrol engines. This turbine housing includes an integrated actuator mechanism with a visible related hardware arm, which is a key feature for verifying the correct variant. Buyers should confirm whether their specific application requires a VNT (variable nozzle turbine) or fixed-geometry design, as the actuator configuration differs between these types. The cast metal housing features a machined mounting flange with three bolt holes and a secondary flanged port with four threaded holes. Verify these mounting details and the actuator related hardware orientation against your engine bay layout. LeadTurbo provides technical fitment support to help validate these details before ordering.
