JDM/USDM Honda Integra 1994-2001 B18C1 B18C5 81mm Wiseco forged pistons. Feature Armor Glide™ on the skirt which minimizes friction, improves wear resistance, and helps increase power; and Wiseco Armor Plating™ which reduces heat on the dome, reduces the effects of detonation, and creates a hard yet smooth surface for the rings to rest on. 8.5:1 compression ratio with .030" head gasket and 41.5cc head. -12cc Dished. The set includes four pistons, four set 8100XX rings, and four 21mm S656 pin and pin clips.
On and off the street, you can depend on the maximum strength and minimum variance of Wiseco's aluminum-forged pistons for your sport compact vehicle. Wiseco's pistons outgun cast and hypereutectic pistons, giving you stronger pistons and tighter tolerances than any other part in your engine, with less internal and external machining. The advanced forging, extensive heat-treat, and finishing process assure you of the performance and reliability you demand from your engine.
Wiseco sport compact pistons feature Generous Valve Pocket Design that allow maximum flow around valve; and Piston Crown shapes designed to promote maximum intake charge efficiency through scavenging mixture "Cross Flow' during intake and exhaust valve overlap, which equates to more fuel and air, thus more horsepower. Wiseco pistons are also designed to optimize squish or quench during the compression-combustion cycle, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential. Additionally, the pistons feature Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal. Wiseco has also added Armor Glide™ coating to most sport compact pistons. This set also has Wiseco's Armor Plating™ which reduces heat on the dome, reduces the effects of detonation, and creates a hard yet smooth surface for the rings to rest on. Every piston features precision CNC machined ring grooves with proper orifice/accumulator volume using calculated groove root diameters and axial widths, and have excellent surface finish and flatness providing maximum ring seal that minimizes blow-by and oil consumption. Finally, Wiseco utilizes the latest technologies featuring forged shapes, advanced materials, and featured aligned grain flow technology, in their world class forging facility.
