4B11 HKS 2.2 Stroker Kit



4B11 HKS 2.2 Stroker Kit – 21004-AM003

Capacity Upgrade Kit 4B11 2.2L
* The plate-shaped item is the crankshaft angle sensor plate. It has processed the stock to install at the HKS forged crank.

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 as the Tsukuba record time holder of CZ200S.


<POINT-1> Big benefits from increased displacement!
 Kit increases 4B11 displacement from the 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 70Kgm 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.
<POINT-2> “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 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
<POINT-3> 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 time attack events. This data was analyzed to deliver maximum performance but most importantly reliability. This item is made in Japan at HKS’ internal manufacturing facilities.
