Bring VSE's newer 2024+ G3 turbo architecture to a 2020-2023 L5P Duramax. The 64/66 conversion is designed to combine additional compressor and turbine airflow with responsive towing and street operation.

• 64 mm billet compressor with a titanium-nitride coating.
• 76 x 66 mm nine-blade turbine and proprietary 11 mm vane cage.
• Upgraded thrust plate, thrust bearing and journal bearings.
• Includes the 2024+ pedestal, actuator, oil-feed line and VSE CAN harness.
• No core return required.

Application notes: Custom tuning and a VGT relearn are required. The original 2020-2023 calibration does not properly control this conversion.
