HKS Step 3 Stroker Kit RB26 2.8L

The HKS Step 3 Stroker Kit for the RB26 engine is built around a 2.8L displacement increase, achieved through a longer stroke crankshaft and larger bore pistons. This is a serious upgrade for those looking to extract maximum performance from their RB26 engine. It's designed for builders who want to push the boundaries of what the RB26 can do, often for dedicated track or race applications where every bit of power matters.

This kit includes a forged crankshaft, forged connecting rods, and forged pistons, all engineered to handle significantly higher power outputs than stock. The crankshaft features a longer stroke to increase displacement, while the pistons are designed to match, often with specific dome shapes to optimize compression and combustion. The connecting rods are also beefed up to withstand the increased forces. HKS is well-known for its precision manufacturing, and these components are made to tight tolerances for reliable operation even under extreme stress. Expect a substantial increase in torque and horsepower, especially in the mid-range, thanks to the larger displacement.

Building an engine with a stroker kit like this is a significant undertaking. It requires careful attention to machining, balancing, and assembly. You'll want to ensure all supporting components, such as the cylinder head, fuel system, and engine management, are up to the task of handling the increased power. This kit is not CARB approved and cannot be shipped to California. Always consult with a professional engine builder or refer to HKS's detailed installation manual for proper assembly and tuning procedures.
