What is the bore size and is it a direct replacement?

These pistons have a bore size of 81.5mm, which is 0.5mm oversize. This means the engine block needs to be bored to this size to properly fit these pistons. They are not a direct drop-in replacement for a stock bore engine.

What is included in this piston set?

This set includes the four forged pistons, a complete set of piston rings for all four pistons, and the necessary premium chrome moly wrist pins.

Are these pistons suitable for all engine builds?

These pistons are designed for performance applications and are not CARB approved, meaning they cannot be shipped to California. They are intended for use in performance-oriented engine builds where the block has been machined to the specified oversize bore.

About this part

Product Details

Built with domestic 2618 alloy forgings, these Manley pistons are a solid choice for anyone rebuilding or upgrading their 1994-2001 Acura Integra GSR's B18C1 engine. They come in an 81.5mm bore size, which is 0.5mm oversize, meaning they're intended for engines that have been bored out to accommodate them. The 9.0:1 dish volume helps achieve a good compression ratio for street performance applications.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them generate power while also being gentler on your cylinder walls, which is important for longevity. The ring lands and grooves are machined to strict standards to ensure a good seal, and they come with premium chrome moly wrist pins. These pistons are made using unique fixturing that allows the skirt to be turned and the ring grooves to be machined in the same operation, ensuring the ring grooves are perfectly square to the skirt.

This set includes the pistons, rings, and chrome moly wrist pins. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For the best results, always refer to the manufacturer's installation instructions and consult with a professional engine builder for proper assembly and tuning.
