RB26DETT engines in the R32, R33, and R34 Skyline GT-R benefit from increased displacement and optimized internals when seeking stronger low-to-mid range torque and higher overall power. The HKS 2.8L Kit STEP ZERO 87mm Full Kit (21004-AN010) is a high-performance upgrade that raises capacity to 2771cc with 87mm forged pistons, a full counterweighted crankshaft, and high-strength H-beam connecting rods. This kit is recommended for stock or GTIII-SS turbo setups, delivering enhanced torque at lower RPM while supporting up to approximately 8000 RPM and target outputs around 549 HP.

HKS uses the highest quality materials and precision engineering to ensure durability under high tuning levels. The nickel-coated pistons provide strong anti-knocking properties, while the fully counterweighted crankshaft and H-beam rods maximize turbo response and overall torque. This kit is ideal for overhauling from standard internals, with boring and honing required for installation, and is designed for reliable performance in both street and competition applications.
