Manley Nissan (SR20DE/DET) 87mm +1.0mm Oversized Bore 8.5:1 Dish Piston Set with Ring

If you're rebuilding the engine in your Nissan SR20DE or SR20DET, this Manley Performance piston set is built for the job. These pistons are designed to be 87mm in bore diameter, which is 1.0mm larger than stock, and feature a dish shape that results in a compression ratio of 8.5:1. This makes them a solid choice for many performance applications where you might be looking to slightly lower compression for forced induction or to accommodate a specific head gasket thickness.

Manley uses their signature 2618 alloy forgings for these pistons, which are known for being strong and reliable under demanding conditions. They also feature proven cam and barrel skirt profiles, which help them run smoothly and quietly while minimizing wear on your cylinder walls. The ring lands and grooves are machined to very precise standards to ensure a good seal with your piston rings, which is crucial for making good power and maintaining compression. Each set comes with premium chrome moly wrist pins, and Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt.

This set is not CARB approved and cannot be shipped to California. It's important to note that these are oversized pistons, so your engine block will need to be bored and honed to the correct size to accept them. Always refer to the manufacturer's installation instructions for precise measurements and procedures.
