This core is a replacement application for the Isuzu 4HG1-T 120HP engine, commonly found in the Isuzu NPR Series truck. It is associated with OEM reference numbers including 704136-0001, 704136-0003, and 704136-5001. Buyers should verify these references against their specific vehicle VIN and engine code to confirm fitment. The application path is listed as Isuzu > Isuzu NPR Series Truck > Isuzu 4HG1-T 120HP. Because this is a reference application, verify the turbo configuration and production year before ordering to ensure the GT2256MS core matches your existing setup.

Technical Notes

The GT2256MS core assembly features a central housing with a two-bolt flange and central port, connecting the compressor and turbine wheels via a central shaft. Visible machining on the compressor housing and mounting flange indicates a polished finish, while the turbine section shows a cast surface. Buyers should verify the physical dimensions of the mounting flange and port alignment against their existing housing or turbocharger before installation. Confirm that the oil feed line restrictor requirements match the service manual for the Isuzu 4HG1-T engine to ensure proper lubrication flow. This core is supplied as a standalone CHRA; verify whether your application requires a complete turbocharger assembly or just the core replacement.
