HKS 23011-AN027 Short Block RB26 3.0L STEP3

• 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.
• A dedicated I-beam connecting rod has been adopted to increase buckling strength by 36%, in preparation for higher torque. The piston pin thickness has also been increased by 22mm.
• 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.

The two-piece piston has a higher pin position making it possible to reduce the compression height. The extremely lightweight 313 g pistons, which have cooling channels for oil cooling.
