Product Description

HKS is proudly introducing their new stroker kit for the popular Mitsubishi Evolution X. Each kit includes select, matched motorsport grade components ensuring maximum reliable performance. The HKS 4B11 2.2L stroker kit combines the perfect bore to stroke ratio, yielding potentially big gains in torque while still allowing the engine to rotate and produce power in the higher rpm range. Designed under the concept of "Race Specification with Low Cost". This kit has been tested not only on the engine bench but through circuit testing and analysis. Using the HKS GT3240 Full Turbine Kit can achieve 580PS and 72kgm, which is the same engine specification of the Tsukuba record time holder of CZ200S


  • Special Order


  • Mitsubishi Lancer EVO X (2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015)


  • Big benefits from increased displacement: Kit increases 4B11 displacement from a stock of 1,998cc to 2,139cc. The difference in displacement creates a massive difference in torque and also makes it possible to match large volume turbines for maximum power. HKS tests have found that over 70 Kgm torque output 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.
  • "Race Specification" at an incredible price: In order to have many people enjoy this kit, the new machine has been invented to reduce manufacturing time and help to reduce the cost * Many competitors use an OEM crank to reduce costs while increasing stroke. The HKS crank has been designed and made for racing specifications by using the most suitable materials and manufacturing processes. Forged pistons, forged connecting rods and a crank made from special forged materials allows this kit to be suitable to even for 600PS
  • Circuit test proven & "Made in Japan" reliability: After plenty of testing on the engine bench, the kit was also tested in conjunction with the GT3240 kit to produce the 600PS CZ200S which went on to perform at various times attack events. This data was analyzed to deliver maximum performance but most importantly reliability. This item is made in Japan at HKS's internal manufacturing facilities.
