Tomei Toyota Supra (93-02) 2JZ-GTE Forged Piston Set - 86.50mm / CH29.50 (3.6)

Introducing the Tomei TA202A-TY03E Forged Piston Set, an exemplary component designed specifically for the Toyota 2JZ-GTE engine. This piston is not merely a part; it is the very heart of your performance build, transforming the energy of combustion into the exhilarating power that propels your vehicle forward. Crafted with the utmost precision, this piston is engineered to withstand the extreme pressures of a tuned engine, ensuring reliability and performance in every rev.

Design & Engineering
At the core of the TA202A-TY03E's design is a lightweight yet high-rigidity forged construction. Tomei employs a high-strength forging method, diverging from the conventional casting techniques prevalent in commercial applications. This advanced manufacturing process allows for an optimal balance of strength and weight, achieved by utilizing thinner wall profiles that do not compromise integrity.

Each piston is forged from exclusive materials tailored specifically for this application, minimizing excess material and eliminating unnecessary machining that could weaken the structure. The result is a component that not only meets but exceeds the rigorous demands of high-performance environments.
