TOMEI Forged Piston Set 87mm For Nissan S13 Silvia 180SX SR22 TA202A-NS08A

Increasing displacement is a proven way to add torque and power potential to the SR platform. The Tomei Forged Piston Set (part number TA202A-NS08A) is an 87.0 mm bore set developed for Nissan S13 Silvia and 180SX engines being converted to an SR22 stroker configuration, producing approximately 2163 cc when paired with the correct longer-stroke crankshaft.

These forged pistons are engineered to handle the elevated cylinder pressures and thermal loads associated with higher-displacement, turbocharged builds. The 87 mm bore increases capacity while maintaining the strength and dimensional accuracy expected from Tomei forged components. As with other Tomei stroker piston kits, this set is designed to be used only with a compatible stroker crankshaft and is not intended for a standard-stroke SR20 application. Piston rings, pins, and circlips are typically included as part of the complete kit.

This 87 mm forged piston package is a core component for serious SR22 stroker builds based on the S13 Silvia or 180SX. Professional machining, balancing, and assembly are required for correct installation. At Terra Firma Automotive, we supply this genuine Tomei Forged Piston Set as a high-quality foundation for increased-displacement SR projects. Whether the goal is stronger mid-range torque or greater overall power capacity, these pistons deliver the material quality and design integrity associated with Tomei. Choose Terra Firma Automotive for authentic Japanese engine internals that support capable SR22 stroker combinations.
