HKS Single Turbocharger GTIII-4R 0.81 A/R WG 14001-AK033

RB26DETT engines in the R32, R33, and R34 GT-R require advanced turbo technology to achieve high power while maintaining reliability and efficiency. The HKS Single Turbocharger GTIII-4R 0.81 A/R WG (14001-AK033) is a high-performance upgrade that combines MHI brand CHRA with HKS proprietary housings and an aluminum forged impeller. This design delivers high boost at low airflow ranges while effectively preventing surging, resulting in exceptional response and versatility for both street and competition applications.

As a successor to the TO4Z, the GTIII-4R is compact yet capable of supporting over 700 PS. The optimized turbine housing and ultimate turbine blades enhance efficiency to levels comparable to ball-bearing types, even with the orthodox floating metal design. The ported shroud function, selectable via adapter, further reduces surging and improves performance by optimizing the intake air path. This turbocharger is built for durability and longevity, making it ideal for serious RB26DETT builds seeking maximum power and consistent operation.
