HKS Short block / engine RB26 3.0L STEP3

[Short block RB26 3.0L STEP3] Newly developed 2-piece piston realizes increased stroke and connecting rod length while maintaining block height. The 3.0L dedicated crank is a full counter machined from nitriding steel, and ion nitriding treatment has increased the surface hardness to the limit and improved fatigue strength. In preparation for higher torque, a dedicated I-section connecting rod is used to improve buckling strength by 36%. In addition, we also adopted a φ22 thicker piston pin. As a countermeasure against the heat generated by the high power output, the valve guide and seat materials have been changed, and a sodium-filled EX valve and a piston with a cooling channel have been adopted. Dedicated full counter crank Dedicated I-beam connecting rod with 36% higher buckling strength and 6mm longer shaft distance Machined 2-piece piston By making the piston two pieces and raising the pin position, it became possible to reduce the compression height. This
