New 10R8733 Caterpillar C13 ACERT Garrett GTA4088 Turbocharger - Turbo Centre Production Line

The 10R8733 Turbocharger is a purpose-matched Garrett GTA4088 assembly for Caterpillar C13 ACERT 12.5L, Twin-turbo C13 ACERT high-pressure position. It is built around the exact compressor, turbine, housing, and control specification associated with part number 10R8733, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

This GTA4088 is the high-pressure turbo in the Caterpillar C13 ACERT compound system. The smaller high-pressure stage responds first, using exhaust energy to build boost quickly at low and mid engine speed before passing compressed air through the larger low-pressure stage. It must work as a matched pair with the 10R2027; leakage, restriction, or damage in either turbo can upset pressure ratios, increase exhaust temperature, and reduce power throughout the system.

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.
