IHI 897119-5671 Turbocharger Assembly

The IHI RHF5 series turbocharger (Manufacturer Part Number 897119-5671) is a water-cooled, wastegate-controlled unit designed for high-volume passenger car and light commercial vehicle engines. This model features a forward-rotation compressor wheel and a two-oil-port bearing housing configuration compatible with both gasoline direct-injection (TSI/TFSI) and common-rail diesel applications. Primary OEM applications include the Volkswagen Group EA888 Gen 1/2 2.0L TSI engines (engine codes CCZA, CCZB, CAWB, CBFA) found in Audi A4/A5/Q5, Volkswagen Passat/Tiguan/Golf GTI, and Skoda Superb/Octavia. Cross-reference data confirms interchangeability with VW/Audi OE numbers 06J145778F and 079145722A. Additional verified fitments cover Isuzu 4JX1-T and 4JA1-L diesel engines (OE 8980907010, 8981869700, 8973132920), Hino J05E/J08E engines, Yanmar 4TNV series industrial engines (OE 123910-18021), and Mercedes-Benz M270/M274 2.0L turbocharged engines. The unit integrates a pneumatic wastegate actuator calibrated for specific boost pressure maps per application. The CHRA (Center Housing Rotating Assembly) utilizes a 360-degree thrust bearing and journal bearings lubricated/cooled by engine oil and coolant circuits. Repair kits and replacement CHRA cartridges (e.g., F51CND-S0200C, 897137-series) are available for service. All rotating assemblies are factory VSR-balanced to ISO 1940/1 G2.5 standards.
