Manley 94-01 Acura Integra GSR (B18C1) 81mm STD Bore 12.5:1 Dome Piston Set with Rings

If you're rebuilding the engine in your 1994-2001 Acura Integra GSR with the B18C1 engine, this Manley 81mm standard bore piston set is a solid choice. These pistons feature a 12.5:1 compression ratio, designed to increase power output when paired with appropriate tuning and supporting modifications. They are built using Manley's signature Platinum Series construction, which professional engine builders trust for demanding applications.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to handle high performance. The pistons also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating substantial power. The ring lands and grooves are machined to strict standards to ensure a good seal, and they come with premium chrome moly wrist pins for added durability. Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, contributing to overall engine health and performance.

This set includes the pistons, rings, and tool steel wrist pins. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, it's recommended to consult with a professional engine builder for installation and tuning.
