Toyota Corolla 3TC with 63cc head 86mm Forged Piston Set. 10.2:1 compression ratio, 20.6cc dome. The set includes four pistons, four set 8700XX rings, and four S625 22mm pins and pin clips. Pistons are forged and CNC machined. High compression for all-motor build.
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. 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.
