Introducing the Stroke-89 Acura/Honda B18A1 Racing Pistons by Wiseco, part number K673M82AP. These high-performance pistons are specifically designed for the B18A1 engine, ensuring optimal performance and reliability.
The Stroke-89 pistons are forged from 2618-T6 aluminum alloy, which provides exceptional strength and durability while keeping weight to a minimum. This alloy is heat-treated to create a microstructural composition that enhances the piston's strength and fatigue resistance.
The piston's top ring land is radiused, which reduces ring drag and friction, resulting in less power loss and improved engine performance. The pistons also feature a chamfered skirt, which provides a smooth transition between the piston and the cylinder wall, reducing friction and promoting better ring seal.
The Stroke-89 pistons are designed with a compression height of 10.200 inches, a piston pin diameter of 0.520 inches, and a wrist pin oiling hole diameter of 0.062 inches. They are also optimized for a stroke length of 89mm, making them an excellent choice for high-performance applications that require increased displacement.
The piston crowns feature a domed shape, which aids in combustion chamber filling and enhances engine performance. The pistons are also equipped with Wiseco's proprietary ring pack, which includes a 1.0mm top ring, a 1.2mm second ring, and a 1.6mm oil control ring. This ring pack provides excellent sealing and oil control, ensuring proper lubrication and reducing the risk of engine blowby.
In summary, the Stroke-89 Acura/Honda B18A1 Racing Pistons by Wiseco are a high-performance upgrade for your engine. They are forged from 2618-T6 aluminum alloy, have a radiused top ring land and chamfered skirt, and are optimized for a stroke length of 89mm.
