Wiseco Volvo B4194T 1.9L 81.5mm Bore 8.5:1 CR Piston Kit

This Wiseco piston kit includes four forged pistons, designed specifically for the Volvo B4194T 1.9L engine. Each piston features an 81.5mm bore and a compression ratio of 8.5:1, making it a solid choice for rebuilding or upgrading your engine's top end. Wiseco is well-known for its forged pistons, which are built to handle higher performance demands compared to cast pistons. This kit is intended for those looking to refresh their engine with durable, performance-oriented components.

The pistons in this kit are forged from high-strength aluminum alloy. This forging process creates a denser, stronger grain structure than casting, which helps the pistons resist deformation and withstand the increased pressures and temperatures found in performance applications. The 8.5:1 compression ratio is a moderate increase over stock for many applications, offering a good balance between improved power and the ability to run on pump gas, depending on your specific engine setup and tuning. This kit is a direct replacement for your original pistons, simplifying the installation process for a qualified mechanic.

When rebuilding your engine, it's important to ensure all components are properly cleaned and lubricated before installation. This kit is designed to fit the specific bore size of 81.5mm. Please note that this kit is not CARB approved and cannot be shipped to California. Always consult your vehicle's service manual or a professional mechanic for detailed installation procedures and torque specifications.
