Manley Nissan SR20DE Piston Set - 87.00mm Bore 1.260in CH, -12.00 CC

Starting with the 2618 alloy forgings, these Manley pistons are built for serious performance in your Nissan SR20DE engine. This material is chosen for its strength, which is crucial when you're pushing an engine beyond its stock limits. The pistons feature a -12.00cc dish, which is a specific design choice that affects your compression ratio when paired with your cylinder head and gasket combination.

Manley doesn't stop at just the material. They've incorporated proven cam and barrel skirt profiles. Think of these as carefully shaped contours on the piston skirt that help it move smoothly within the cylinder wall. This design helps generate substantial power while also being gentler on the cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is key for getting a solid seal from your piston rings. A good ring seal means better compression, less blow-by, and ultimately, more power from your engine.

Included with these pistons are tool steel wrist pins, which are known for their durability. For those looking for even more robustness, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. Manley's unique manufacturing process allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which further contributes to that all-important ring seal. These are the kind of components professional engine builders and tuners rely on when they need dependable performance and durability.
