Product Description

The HKS 11004-AN014 GTIII-2530 Sports Turbine Kit is a direct-replacement twin-turbo upgrade engineered specifically for the Nissan Skyline GT-R's RB26DETT engine across all three generations - R32, R33, and R34. Using a parallel twin-turbo configuration with lightweight GTIII-2530 compressor wheels, this kit delivers a noticeably more linear and responsive boost curve compared to the factory ceramic turbines, making it an ideal first-step forced induction upgrade without requiring major drivetrain modifications.

Each turbocharger ships preset at 88.3 kPa (0.9 kgf/cm²) and includes adjustable actuators for fine-tuning boost to match your build level. With supporting engine work, this kit is capable of reaching 600ps, making it a solid foundation for both street-tuned and track-focused GT-R builds. The improved oil feed and coolant pipe routing enhances long-term reliability and simplifies installation compared to previous-generation HKS turbine kits.
