FEATURES:_x000D_
Big benefits from increased displacement!_x000D_
- Kit increases 4B11 displacement from stock 1, 998cc to 2, 139 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._x000D_
NOTE: 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._x000D_

Race Specification at an incredible price!_x000D_
- 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._x000D_
NOTE: Many HKS competitors use an OEM crank to reduce costs 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 kit to be suitable to even 600PS_x000D_
_x000D_
Circuit test proven & Made in Japan reliability!_x000D_
- After plenty of testing on the engine dyno, the kit was tested in conjunction with the GT3240 kit to produce the 600PS CZ200S which went on to perform at various time attack events. This data was analyzed to deliver maximum performance but most importantly reliability. Naturally, this item is made in Japan at HKS' internal manufacturing facilities.
