Tomei TA4070-NS08G and Tomei 88.0-1.8mm Head Gasket Nissan Silvia SR20DE SR20DET 99-02

Tomei: A Legacy in Performance Engineering

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years, Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei's racing heritage means their research and design team have first-hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei's products can handle the intense strain and heat a purpose-built engine will experience whether it be on the street or the track. Tomei's attention to detail is second to none.

TA4070-NS08G: Precision Engineering for Performance

All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because even minuscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

TA4070-NS08G: The Ultimate Head Gasket Solution

With the increase in combustion pressure from performance engines in recent years, the burden placed on the head gasket has grown tremendously. To maintain the highest precision possible in a high-performance assembled engine, strict measurements and maximum sealing are required. The right torque values on each head stud and bolt are crucial to keep everything together and gain the most out of your engine.

When bolts are screwed into place, regardless of the bolt type and strength qualities, the pressure is always on the first three threads of the screw, which takes the most stress. If the cylinder block is badly distorted, then the screw threads can be damaged as well. Stud bolts with dynamic designs allow the screw bolt to take on equal stress on all threads, securing maximum sealing pressure for race and airplane engines.

Since the cylinder capacity can fluctuate with the thickness of the gasket used, the compression ratio can be adjusted with the thickness of the gasket. The gasket thickness will help with the final adjustments to get your setting closest to the target compression ratio.

Stainless steel was chosen as the head gasket material due to its heat conductivity efficiency, which evenly distributes heat and aids with cooling. This greatly improves reliability and reduces the chances of a blown head gasket. The natural high tensile qualities of stainless steel also increase the joint rigidity of the cylinder head with the cylinder block, minimizing the chances of the engine warping under severe stress loads that performance engines endure.
