Manley Performance 85.5mm +0.5mm Overbore Dish Pistons for Mitsubishi 4G63T Engines (Part# 606005C-4)

Description

Upgrade your Mitsubishi engine with the Manley Performance Platinum Series pistons, specifically designed for 4G63T turbocharged engines. These high-performance pistons feature 2618 alloy forgings, which provide exceptional strength and durability under demanding conditions. The precise cam and barrel (skirt) profiles are engineered to optimize power output while maintaining gentle interaction with cylinder walls, ensuring long-lasting performance. Each piston is equipped with chrome moly wrist pins as standard, with options for upgraded 9310 or Turbo Tuff/DLC alloys for enhanced durability in high-stress environments.
Manley’s strict manufacturing standards include meticulous ring land and groove machining, resulting in better ring seal and increased power. The unique fixturing process allows for integrated skirt turning and ring groove machining in a single operation, guaranteeing ring-to-skirt squareness and consistent quality. These pistons are designed to fit a range of Mitsubishi models including the Eclipse, Lancer, and Eagle Talon from the early 1990s through the mid-2000s, making them an ideal choice for performance enthusiasts and professional engine builders alike.
Constructed with attention to detail, the pistons come with a 8.5:1 compression ratio and are suitable for use in high-performance applications requiring a bore size of approximately 85.5mm with an additional 0.5mm overbore. The dish design helps reduce compression while maintaining excellent combustion characteristics. Please note that these pistons are not CARB approved and require acknowledgment of this status. Designed for use in turbocharged engines, they provide a reliable and durable solution for creating more horsepower and torque for street or race applications.
