RB26DETT engines in the R32, R33, and R34 Skyline GT-R offer tremendous potential when converted to a single turbo setup, but building one properly requires a strong foundation of high-quality components. The HKS Special Set Up Kit Without Single Turbocharger GTIII-4R (14020-AN011) provides exactly that — a complete collection of precision-engineered parts designed specifically for a professional GTIII-4R (or similar) single turbo conversion. At its core is a robust HKS cast exhaust manifold that optimizes exhaust flow and thermal management, paired with an HKS φ60 special wastegate and return pipe for accurate and stable boost control.
The kit also includes dedicated oil inlet and outlet pipes, along with a full set of flanges, gaskets, bolts, and nuts, ensuring a clean, reliable installation with proper sealing and durability under high-boost conditions. This setup is engineered for direct fitment on R32, R33, and R34 GT-R models, giving builders a solid platform to achieve significant power gains while maintaining good drivability. Note that the turbocharger itself is not included, and some additional fabrication (such as intake piping) may be required depending on your specific turbo choice and vehicle configuration.
At Terra Firma Automotive, we supply this genuine HKS Special Set Up Kit as a premium foundation for custom high-performance single turbo RB26DETT builds. It reflects HKS’s uncompromising standards for quality and performance, helping you create a powerful, responsive engine that makes the most of a larger turbo while preserving reliability. For enthusiasts planning a serious single-turbo conversion on their Skyline GT-R, this HKS kit is one of the most complete and well-engineered supporting solutions available.
