Description
The HKS Piston Full Kit provides the listed capacity-upgrade configuration for an engine build. Application: RB26.
Design and operation
Increasing displacement requires a coordinated relationship between crankshaft stroke, piston dimensions and connecting-rod geometry. The stated capacity applies to the specified combination and its required machining and clearances.
Technical details
- Manufacturer part number: 21004-AN009.
- Configuration: 2.8 L / Step Zero / 86.5 mm
- Application: RB26.
- Engine designation: RB26DETT.
- Published build displacement: 2739 mL.
- Bore / pin-size designation: φ86.5 - φ21.
- Published boring / honing requirement: required.
- Package / component specification: Forged piston 86.5mm + Full counterweighted crankshaft + H-beam Con'rod.
Application-specific requirements
- "STEP ZERO" is recommended for stock or GTIII-SS turbine as more power cannot be output at more than 8,000rpm, and STEP ZERO has the best response.
Installation and selection
Confirm the exact supplied-component list and any required companion parts. Engine assembly should include bore, bearing, ring-gap and clearance checks, followed by calibration for the completed combination.
