Built using Wiseco's extensive racing experience, these forged pistons offer superior strength and optimal design for applications making over 350 horsepower per cylinder.\n\nConstructed from dedicated, in-house produced forgings, these pistons are lightweight yet incredibly strong. They feature specialized valve pockets, complex dome and crown shapes, and steel nitride\/napier xx rings for multivalve technology. The optimized skirt profiles and ArmorGlide® coating reduce friction and noise, contributing to increased horsepower. The pistons utilize special 22mm tool steel pins with a .225\" wall thickness, and the 1400HD forging is strutted for enhanced durability. The available options include a standard 86.50mm bore with a 9.7:1 compression ratio, or an 87.00mm (.020\" overbore) with a 9.8:1 compression ratio.\n\nThis piston set is designed for a 100mm stroke using 150mm rods. It is compatible with the 7-bolt 4G63 engine found in 1992.5-1999 1G\/2G Eclipse GST\/GSX, Talon TSi, and Laser Turbo models. Each set includes four pistons, four pins, eight wire locks, and four sets of piston rings.","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":52866727772472,"sku":"K626M88","price":958.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687414233.jpg?v=1787909560","url":"https:\/\/store.motormia.co\/products\/forged-piston-set-86-50mm-bore-9-7-1-compression-22mm-pin","provider":"MOTORMIA","version":"1.0","type":"link"}
