RB26DETT engines under high boost and aggressive tuning place enormous stress on the cylinder head gaskets, often exposing the shortcomings of the original equipment design. The Tomei Cylinder Head Gasket (TA4070-NS05C) in 87.0-1.8mm is a high-performance upgrade that uses a multi-layer steel construction with advanced super grommet sealing technology. By reinforcing the areas around the bore and water/oil passages, this gasket set provides exceptional resistance to high surface pressure, heat, and boost levels commonly found in modern tuned RB26 engines.
Tomei’s meticulous development process focused on real-world performance demands, resulting in gaskets that maintain perfect sealing integrity even under extreme conditions. The premium-grade materials and specialized coatings ensure long-term durability while the engine-specific design delivers precise water and oil route sealing that prevents leaks and maintains consistent performance. Multiple thickness options also give builders the flexibility to fine-tune compression ratios when combined with other Tomei components, making this set a versatile and essential part of any serious RB26 project.
At Terra Firma Automotive, we supply this genuine Tomei Cylinder Head Gasket as a critical reliability component for serious RB26DETT enthusiasts. Replacing the stock head gasket with Tomei’s advanced multi-layer design eliminates a common source of failure and gives you the confidence to run higher boost and more aggressive cam profiles. Whether you’re refreshing a daily driver or assembling a track monster, these gaskets deliver the quality and performance expected from Tomei’s renowned engineering, helping your RB26 run stronger and more reliably for years to come.
