The pinnacle model of the RB26 Complete Engine. Newly developed 2-piece piston achieves increased stroke and connecting rod length while maintaining the same block height.
The exclusive 3.0L crank is machined from high-end race grade nitride steel that is ion plasma treated to increase surface strength and toughness.
In preparation for high torque, dedicated I-beam connecting rods with 36% increase buckling strength and a 22mm thicker piston pin were adopted.
Various design changes were made to countermeasure against heat generated during higher output, such as, changes to valve guide and seat materials, adoption of sodium-filled EX valves, and pistons with cooling channels
Dedicated 36-tooth crank angle sensor and crank angle sensor for V-cam improve signal accuracy in the high-RPM range.
※Recommended engine oil is HKS Racing Pro 10W50.
