Lamspeed Racing - Custom Wiseco Forged Pistons - 2.2L 9.5:1CR - Mitsubishi 4G63

Details:

Lamspeed Racing Custom Wiseco Forged Piston Set for the Mitsubishi 4G63 Engine, in 2.2L 85.5mm Oversized configuration.

We have taken one of the best pistons on the market, and improved it. The Lamspeed Racing Pistons are based on the renowned Wiseco 1400HD line of pistons, developed for extremely high horsepower applications.

NOTE: Pistons come in a set of 4.

1400HD features

• Utilises a 2618 alloy, the strongest available on the market today, with the best strength at high temperatures, coupled with low silicon content, for low porosity.
• Heavy Radii, creating a large smooth radii from the skirts and pin boss into the crown, preventing flex and cracks.
• Includes .225" wall Tool Steel Wrist Pins and heavy duty rings
• Valve pocket design that allows maximum flow around valves - allows oversized valves and high lift cams to be utilized.
• Piston crown shape designed to promote maximum intake charge efficiency through scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower!
• Pistons designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition.
• Complex piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal.

Lamspeed Racing features

• 1400HD features per above, plus
• Hard anodized tops
• Thicker side walls
• DLC (diamond like coating) pins
