Product Details

The Wiseco K682M89 is a high-performance forged piston kit designed for the Honda F20C and F22C engines found in the S2000. Featuring a +7cc dome and an 11.0:1 compression ratio, this kit is engineered for naturally aspirated performance builds demanding maximum power and reliability. Each piston is forged from 2618 aerospace-grade aluminum alloy, which increases material density and aligns the grain flow for superior strength, impact resistance, and ductility compared to cast alternatives.

Key Features:

  • Bore: 89.00 mm (+2.00 mm oversize)
  • Compression Ratio: 11.0:1 actual
  • Dome Volume: +7.0 cc
  • Compression Height: 28.98 mm (1.141 in.)
  • Piston Pin Diameter: 23.00 mm (0.9055 in.)
  • Material: 2618 high-strength forged aluminum alloy
  • ArmorGlide® skirt coating for reduced friction, quieter operation, and seizure resistance
  • Fully machined crown with precision ring grooves
  • Ring set (P/N: 8900XX) included
  • Made in the USA

Important Note: Honda F20C and F22C engines use FRM (Fiber Reinforced Metal) cylinder liners. Aftermarket sleeves are required when running these pistons — do not install in bare FRM bores.

Wiseco pistons are engineered, forged, and CNC-machined at their Mentor, Ohio facility. This kit is purpose-built for high-revving, high-compression naturally aspirated Honda S2000 applications, making it an ideal choice for track, time attack, and road race builds.
