The HKS Super Cooling Overhaul Gasket Kit for the RB26DETT with an 88mm bore and 1.2mm grommet type head gasket is engineered for high-performance applications where cooling and sealing reliability are critical. Designed for Nissan Skyline GT-R owners who demand more from their engines, this kit combines superior materials with advanced engineering to withstand the pressures of aggressive street and circuit use. The grommet type head gasket ensures excellent sealing strength under high boost and elevated cylinder pressures, while the enlarged water passages improve coolant flow and reduce temperature fluctuations between cylinders. This leads to a more stable combustion process, enhanced durability, and a higher resistance to knock ignition limits.
Unlike standard gasket kits, the Super Cooling version is optimized for engines that run higher power levels, where maintaining consistent head cooling is essential. The 1.2mm thickness is particularly valuable during rebuilds that involve cylinder head surface machining, helping restore proper compression and sealing integrity. HKS testing demonstrated significant reductions in cylinder-to-cylinder temperature variation, proving the effectiveness of this design. For maximum performance, pairing with reinforced head bolts further enhances sealing capability, making this kit ideal for long-term reliability under demanding conditions.
In addition to the advanced head gasket, this overhaul kit includes essential supporting gaskets such as valve cover, crankshaft, cam seals, and oil gaskets required for a complete engine rebuild. Terra Firma Automotive offers this premium HKS gasket kit as a comprehensive solution for RB26 enthusiasts who value precision, strength, and cooling efficiency in their builds.
