CAPACITY UPGRADE KIT RB26DETT 2.8L STEP2

Forged piston kit + lightweight forged crankshaft + H-section connecting rod

Piston: Made of special forged material. The head is nickel-plated to improve knock resistance and strength against top ring tilt. In addition, the skirt is obercoated to prevent seizure, reduce friction, and optimize clearance, including initial familiarity.

Connecting rod: Made of special forged material. H-section to withstand powerful explosive load. WPC processing is also performed to improve fatigue strength. (STEP2 exclusive)

*Genuine connecting rods can also be used.

Crankshaft: Made of special forged material. In addition, full counter provides good rotation balance and allows for high rotation. Response is improved by reducing weight through hollowing out the pin journal and center.

Recommended for race-spec engines that require power and response.

The expected rotation speed is 9000 rpm, and it is recommended for combination with GTIII-RS, GTIII-4R, etc.

Allowable speed: 9000 rpm
Maximum power output: 588 kW (800 hp)
