The HKS turbine flange adapter converts a GTIII-4R turbine flange to a GTIII-5R interface. This compact fabrication component is intended to adapt turbocharger housings and turbine outlets where a change in flange specification is needed, simplifying compatibility between different GTIII housings without requiring broader fabrication assumptions beyond the explicit adapter function.
