HKS 2.2L 91mm Stroker Kit for 4B11 Evo X (86.5mm dia Pistons)

Notes:

• Designed under the concept of "Race Specification with Low Cost", this kit has been developed not only on the engine dyno, but through circuit testing and analysis. Achieve the same engine specification as the Tsukuba record time holding CZ200S (580PS / 7
• 2Kgm) when used with HKS GT3240 Full Turbine Kit. Features: 1) Big benefits from increased displacement! Kit increases 4B11 displacement from stock 1,998cc to 2,139cc. The difference in displacement creates a massive difference in torque and also makes it
• possible to match large volume turbos for maximum power. HKS tests have found that torque outputs of over 70Kgm is possible. HKS demo car with this kit and GT3240 full turbo kit has already proven its ability by achieving a time of 57 seconds at Tsukuba
• 2000 circuit. 2) "Race Specification" at an incredible price! In order to have as many people enjoy this kit as possible, a new machine has been invested in to reduce manufacturing time helping to reduce cost. Many competitors use an OEM crank to reduce c
• osts whilst increasing stroke. The HKS Crank has been designed and made to racing specifications using the most suitable materials and manufacture ring processes. Forged pistons, forged conrods and a crank made from special forged materials allows this ki
