Manley Mitsubishi 4B11 86.5mm Bore 9.0:1 CR -5cc Dish Turbo Tuff Piston Set w/ Rings

If you're building a high-performance Mitsubishi 4B11 engine, Manley's Turbo Tuff piston set is a solid choice. These pistons are designed for demanding applications where strength and reliability are paramount. They feature an 86.5mm bore and a 9.0:1 compression ratio with a -5cc dish, making them suitable for turbocharging and achieving significant power gains.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their superior strength and ability to withstand high temperatures and pressures. The pistons also come with premium chrome moly wrist pins, and for this specific Turbo Tuff series, you get enhanced durability with upgraded wrist pin alloys. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal for the piston rings, leading to more efficient combustion and improved power output. Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt, further contributing to optimal ring seal and reduced cylinder wall wear.

This set includes the pistons and rings, ready for installation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
