Wiseco Toyota 20R 2.2L 94mm Bore +4mm Oversized 9.89 CR Piston Build on Demand Kit

Wiseco is known for making well-built performance engine components, and this Professional Series piston kit for your 1981-1983 Toyota Celica is no exception. If you're building a serious performance engine for your Celica, these pistons are designed to handle the demands of heavy to severe duty race applications. They are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to withstand higher stresses.

This kit features a 94mm bore, which is +4mm oversized from stock, and a 9.89 compression ratio. You'll also find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The pistons come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their durability and performance in demanding builds.

This set includes four pistons, ready for your engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
