Supertech Forged Piston Kit - B-series Non-VTEC (B18A/B-B20)

Supertech pistons are manufactured from extruded high silicon, enhanced 4032 alloy that low thermal expansion, excellent wear resistance and higher thermal conductivity. A phosphate dry lubricant coating is applied to pistons to protect against ring micro welding and enhance skirt lubrication.


  • Forged from enhanced 4032 alloy and CNC machined
  • Contact reduction grooves are standard
  • Honed & reamed pin bores and precise fit
  • High tensile strength and evenly distributed hardness
  • Withstands up to 42psi of turbo boost, w/alcohol, w/out any problems
  • A 2 or 3 forging steps process yeilds a fine structural grain oriented in fibers in the same direction of the stresses.
  • Wrist pins are constructed or cold extruded chrome molly steel for high strength to be used with the wire clip locks.
  • Quality Control is performed after every step of the manufacturing process in climate controlled environments to ensure reliability of dimensions
  • Rings, wrist pins, and wire locks are included
