Precise control over quench and compression is often required when assembling a high-performance RB26DETT with oversize pistons. The Tomei Cylinder Head Gasket (part number TA4070-NS05D) is a multi-layer performance gasket designed for the Nissan RB26DETT with an 88.0 mm bore and a 1.2 mm thickness, providing a thinner sealing option for builders who need a lower stack height.
Tomei engineered this gasket to improve sealing strength under the elevated cylinder pressures common in modified RB26 engines. The multi-layer construction and reinforced design help maintain a consistent seal around the combustion chambers, coolant passages, and oil routes. The 88.0 mm bore supports oversize piston applications, while the 1.2 mm thickness allows tighter control over deck clearance and compression ratio during engine assembly.
This single head gasket is a practical choice for performance-oriented RB26DETT builds in the Skyline R32, R33, and R34 GT-R that require both an oversize bore capacity and a thinner gasket profile. At Terra Firma Automotive, we supply this genuine Tomei Cylinder Head Gasket as a reliable sealing component for serious engine work. Whether the project involves a careful overhaul or preparation for higher output, a properly specified head gasket remains fundamental to long-term durability. Choose Terra Firma Automotive for authentic Japanese engine components that support quality RB26 builds.
