The GT2256V is a variable-geometry turbocharger design, where the nozzle ring assembly controls exhaust gas flow through adjustable vanes. This configuration is associated with improved efficiency and reduced lag in general technical references. For this specific part, verify that the vane mechanism and housing profile match your existing unit. Confirm the V-band clamp size and profile, as well as the O-ring material for oil and water connections, to ensure proper sealing and operation.

Inspect the O-ring material for oil and water connections to ensure it matches the thermal and chemical requirements of the OM612 engine application. Replace any degraded seals during installation.
