Wiseco Toyota 2JZ -3.5cc Dome 86mm Piston Set Shelf Stock

This is a set of Wiseco forged pistons specifically made for the Toyota 2JZ engine, featuring an 86mm bore and a -3.5cc dome. These pistons are designed to be a shelf-stock replacement, meaning they are readily available and built to fit the 2JZ engine without custom modifications for bore size. The forged construction offers a strong and durable option for engine builds, especially those looking to handle increased performance demands.

Wiseco is well-known for its piston manufacturing, and this set is no exception. The -3.5cc dome is a specific design feature that affects the compression ratio when paired with your cylinder head and block combination. Forged pistons start as a solid block of aluminum that is heated and hammered into shape, creating a grain structure that is much stronger and more resistant to detonation and fatigue compared to cast pistons. This makes them a popular choice for performance applications where reliability under stress is crucial. The 86mm bore size is a standard dimension for many 2JZ builds, but it's important to ensure this matches your engine's requirements, especially if you've already bored your block.

This set includes all the pistons needed for a complete engine rebuild. When installing these pistons, remember to follow the manufacturer's recommended clearances and lubrication procedures to ensure optimal performance and longevity. While these are shelf-stock items, always double-check your engine's specific needs and consult with your engine builder or mechanic to confirm they are the right fit for your particular build goals. Please note that this part is not CARB approved and cannot be shipped to California.
