In the heart of the engine assembly, from the combustion chamber to the cylinder, a resilient piston operates, seamlessly converting explosive energy into smooth rotational motion. Enduring the harshest conditions within the engine, the piston faces unrelenting forces and extreme temperature fluctuations. As a pivotal component facilitating the transfer of combusted energy to mechanical movement, the piston demands exceptional strength to withstand these rigorous challenges. While standard OEM pistons, crafted from cast metal, excel in mass production scenarios, they falter in highly modified engines generating over 100 horsepower per cylinder.

To elevate performance and surpass stock limitations, our pistons are meticulously forged from a robust aluminum alloy. This forging process empowers the metal to endure conditions that extend far beyond conventional levels. Our forged pistons boast the resilience to withstand combustion pressures reaching 200 kgf and forces totaling 11 tons, even amidst combusted gas temperatures soaring up to 2,500 degrees Celsius. Notably, TOMEI pistons, integral to the finely-tuned RB26 and SR20 engines, mirror the caliber used in the demanding realms of Group C and F1 racing.

The meticulously designed kit, featuring pistons, piston rings, pins, and circlips, is tailored with precision and expertise. Embrace the epitome of durability and performance with our forged pistons, engineered to elevate your engine’s capabilities to new heights.
