RB26DETT engines in the R32, R33, and R34 Skyline GT-R offer legendary tuning potential, but the factory twin-turbo setup eventually limits power on built engines. The HKS GTIII 2530 Twin Sports Turbocharger Kit (11004-AN014) is a direct performance upgrade featuring a parallel twin-turbo layout with new HKS turbines and lightweight compressor wheels. This design delivers linear boost response and exceptional drivability, making it an ideal choice for enthusiasts seeking both street manners and serious track capability.
The kit includes specially designed adjustable performance actuators that allow precise boost control, while strengthened turbine actuators ensure stable operation under high load. Dedicated turbine coolant oil feed pipes and water inlet/outlet lines enhance durability and simplify installation. The full hardware package — flanges, gaskets, bolts, and nuts — provides everything needed for a professional fitment on RB26DETT-powered vehicles. With appropriate engine modifications, fueling, and tuning, this kit supports up to 600 PS while maintaining smooth, surge-resistant power delivery across the RPM range.
At Terra Firma Automotive, we supply this genuine HKS GTIII 2530 Twin Sports Turbocharger Kit as a premium Japanese upgrade for serious RB26DETT builders. It transforms the factory twin-turbo character into a more responsive and powerful system without sacrificing the balanced drivability that makes these Skylines special. For enthusiasts ready to push their R32, R33, or R34 GT-R to higher performance levels while keeping reliability in focus, this HKS GTIII 2530 kit represents one of the most advanced and well-engineered twin-turbo solutions available.
