New 171702 Detroit Diesel Series 60 12.7L DDEC III BorgWarner S400 Turbocharger - Turbo Centre Production Line

The 171702 Turbocharger is a purpose-matched BorgWarner S400 assembly for Detroit Diesel Series 60 12.7L DDEC III, Non-wastegated Series 60 highway and vocational applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 171702, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 171702 is the non-wastegated S400 configuration used on Detroit Series 60 DDEC III engines. Its simple fixed-geometry layout is valued for durability, steady airflow, and predictable boost under long highway pulls. Because boost is controlled by the matched compressor and turbine sizing rather than a wastegate or electronic vane system, correct engine calibration, exhaust housing specification, and charge-air integrity are essential to preserve the factory power curve.

This listing is supplied as the turbocharger configuration shown. Correct installation requires clean oil feed and drain paths, a sealed charge-air and exhaust system, proper air filtration, and confirmation that the original failure did not leave debris or contamination in the engine system.

Turbo Centre Production Line units are assembled from new components to controlled specifications. The rotating group is balanced, bearing clearances and oil passages are checked, housings and control hardware are inspected, and wastegate or vane operation is verified where applicable before shipment. The result is a direct-replacement turbo built for dependable highway, vocational, fleet, and industrial service without a core return requirement.
