The listed options include three HKS RB26 turbine kits, plus a gasket set and an intercooler; the product details do not confirm that any turbine kit is a complete single-turbo conversion package. The HKS GTIII-4R setup is the option to investigate for a larger-turbo build, while the GTIII-SS and GTIII 2530 listings offer other HKS turbine-kit choices. Check each kit’s exact configuration and included hardware before buying, especially if converting an RB26 from its original twin-turbo arrangement.

HKS GTIII-SS RB26 Sports Turbine Kit
This HKS listing identifies a GTIII-SS sports turbine kit for the GT-R RB26. The supplied features describe HKS’s tuning and exhaust-technology background, but do not specify the turbine count, power range, included components, or whether the kit supports a single-turbo conversion.
Best for: RB26 owners who want to investigate an HKS GTIII-SS option and can confirm the exact configuration with the seller or manufacturer. It is selected because it is explicitly listed for the GT-R RB26.
Limitation: The listing details provided are not enough to verify that it is a complete single-turbo kit. The product description also mentions a washable urethane part, but does not clarify its relationship to the turbine kit.
HKS RB26 GTIII-4R Setup Kit
The product name identifies an HKS setup kit for an RB26 with a GTIII-4R. No additional features are supplied, so the listing information here does not establish what hardware is included, the intended vehicle fitment, or whether the kit is configured for a single-turbo conversion.
Best for: Buyers specifically comparing a GTIII-4R-based RB26 setup. It is included because the product name directly pairs the RB26 with this turbine designation.
Limitation: Treat the listing as a starting point for research rather than confirmation of a complete kit. Verify the parts list, installation requirements, and turbo arrangement before ordering.
HKS GTIII 2530 RB26 Turbine Kit
This HKS product is named a GTIII 2530 sports turbine kit for the RB26. The supplied information does not give performance figures, included parts, or installation details, so buyers should compare the full manufacturer or seller description before choosing it over the other HKS options.
Best for: RB26 owners comparing a GTIII 2530-labeled HKS turbine kit with the GTIII-SS and GTIII-4R listings. It was selected because the product name specifies both the RB26 and the turbine family.
Limitation: The provided product data does not confirm single-turbo configuration or vehicle-specific fitment. Do not assume those details from the product name alone.
KINUGAWA RB26 Turbo Gasket Set
This KINUGAWA Store listing is a gasket set described as compatible with the Nissan Skyline RB26DETT and T25 or GT28 twin-turbo applications. The listed feature is simply “Gasket,” so the number and types of gaskets are not specified in the supplied information.
Best for: Buyers looking for gasket parts for a listed RB26DETT T25 or GT28 turbo application. It is included as a supporting maintenance item, not as a turbo kit.
Limitation: The product name references twin-turbo applications. Confirm that the gasket selection matches the specific manifold and turbo arrangement in your build.
PKSABB RB26DETT Front-Mount Intercooler
This front-mount intercooler kit is listed for the Nissan Skyline R33 and R34 GTR with an RB26DETT. The provided feature claims a pressure drop of 0.5–1 psi at 23 psi, compared with 2.8–4 psi for a normal bar-and-plate intercooler at the same pressure. These are listing claims, not independent test results.
Best for: R33 or R34 GTR owners researching an intercooler as part of a broader RB26 build. It is a supporting cooling component, not a single-turbo kit.
Limitation: The listed application does not establish compatibility with every modified setup. Confirm fitment and included piping or hardware before purchase.
Buying Guide: How To Compare RB26 Turbo Options
Does the listing confirm a single-turbo conversion?
Not in the product details provided here. A turbine kit name alone does not confirm that a package converts an RB26 from twin turbos to one turbo. Check whether the package includes the required manifold, turbo, oil and coolant lines, intake and exhaust connections, and other conversion-specific parts. Ask for a complete parts list before purchasing.
Which HKS option should you investigate?
Choose based on the exact turbine designation and the complete specifications for your build. The GTIII-SS, GTIII-4R, and GTIII 2530 names identify different listed HKS options, but the supplied data does not provide enough detail to rank their output or response. Compare manufacturer specifications and confirm the intended turbo arrangement.
What fitment details should you verify?
Confirm your vehicle generation, engine, manifold layout, and existing turbo configuration. Also check what is included and whether additional fabrication or supporting parts are required. For the gasket set, verify the turbo type and gasket contents. For the intercooler, confirm vehicle fitment and connection details.
