Manley 97-00 Honda CRV (B20B4 w/ B16A1-A20A3) 85mm +1.0mm Oversize Bore 12.5:1 Dome Piston Set with

If you're rebuilding the engine in your 1992-2001 Honda Prelude, especially if you're aiming for more power, this set of Manley 85mm +1.0mm oversize forged pistons is a solid choice. These pistons feature a 12.5:1 compression ratio dome, designed to work with specific B-series engine configurations like the B20B4, B16A1, and A20A3, offering a significant bump in performance over stock.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to handle higher performance demands. They also come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring lands and skirt machining are perfectly square, which helps with ring seal and overall engine efficiency. The cam and barrel skirt profiles are carefully shaped to help generate power while also being considerate of your cylinder walls during operation.

This set is 1.0mm oversize, meaning your cylinder bores will need to be machined to 85mm to accommodate them. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings, connecting rods, and gaskets to match these high-performance pistons.
