Manley Subaru FA20 86.25 +.25mm -13cc Dome 10.0:1 CR Extreme Duty Dish Pistons w/ Rings

Manley's Extreme Duty Dish Pistons are built using their signature 2618 alloy forgings, a domestic material known for its exceptional strength and performance under demanding conditions. These pistons are specifically designed for the Subaru FA20 engine, featuring a bore of 86.25mm and a dish volume of -13cc, which helps achieve a 10.0:1 compression ratio. This makes them a solid choice for rebuilding or upgrading your engine's top end, aiming for improved power and reliability.

You'll find that Manley pays close attention to the details that matter for engine longevity and performance. The pistons come with premium chrome moly wrist pins, and for select applications like this one, they offer upgrades to even more durable alloys like 9310 and Turbo Tuff/DLC. The ring lands and grooves are machined to exacting standards, which is crucial for a proper ring seal, ultimately leading to more efficient combustion and increased power output. Manley also utilizes proven cam and barrel skirt profiles, designed to generate power while minimizing wear on your cylinder walls. Their unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ultimate squareness between these critical areas.

When you're building an engine that needs to perform, using well-built components like these Manley pistons is key. They are a popular choice among professional engine builders and tuners who rely on Manley for superior performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
