This BorgWarner KKK K16 series turbocharger (Part Number 5316-970-6002) is engineered for 1.9-liter turbocharged diesel applications in Fiat and Lancia passenger vehicles. The unit features a K16-2260GGB4.90GABHB compressor housing configuration with a 54.8mm compressor wheel inducer diameter. The center housing rotating assembly (CHRA) utilizes a full-floating bearing system with oil-fed lubrication and water-cooled bearing housing for thermal management. The turbine housing incorporates a wastegate actuator for boost pressure regulation.

The compressor wheel (Part Number 5316-123-2005) and shaft-wheel assembly (Part Numbers 5316-120-2101, 5316-120-2103) are precision balanced to ISO standards. This turbocharger supersedes OEM references 53169886002 and 53169706000 series. It serves as a direct replacement for the original equipment turbochargers installed on Fiat Regata, Ritmo, and Lancia Prisma 1.9 Turbo Diesel models produced between 1985 and 1989. Back plate BP-K023 is compatible with this core assembly.
