The Tomei Stroker Kit 4B11 EVO X 2.3L 86.50 (TA201A-MT02B) is engineered for Mitsubishi EVO X builders who want significantly more torque, faster turbo spool, and a stronger performance foundation for high-power setups. By increasing displacement to 2.3L, this stroker kit transforms the powerband with improved midrange pull and quicker response — making the 4B11 feel more aggressive throughout the RPM range.

Designed as a complete matched rotating assembly, Tomei’s stroker kit is built for high-load, high-RPM environments where OEM internals become the limiting factor. The longer stroke configuration increases overall displacement while maintaining reliability for serious street or track builds running elevated boost levels.

Whether you’re building a responsive street EVO or a high-horsepower track setup, this kit provides the strong internal foundation needed to safely push power further.
