Wiseco Toyota 2JZ -5.5cc Dome 86.50mm Piston Set Shelf Stock

Wiseco is well-known for making strong internal engine components, especially for performance applications. This piston set is built for the Toyota 2JZ engine, a popular choice for builds aiming for serious power. These are shelf stock pistons, meaning they are ready to go for your project without a long wait.

Each piston in this set has an 86.50mm bore and a -5.5cc dome. This specific dome volume is designed to work with certain compression ratios, often aiming for a slightly lower compression than stock, which is beneficial when you plan to use forced induction like a turbocharger. The pistons are forged, a process that makes them incredibly strong and durable, able to withstand the higher cylinder pressures and temperatures that come with performance tuning. This strength is crucial for keeping your engine reliable when you're pushing its limits.

This set includes the pistons themselves. You'll want to ensure you have the correct piston rings, wrist pins, and connecting rods for your specific build, as these are typically sold separately. Because these are performance parts, it's always a good idea to consult with your engine builder or refer to Wiseco's technical documentation to confirm compatibility with your chosen crankshaft, connecting rods, and cylinder head to achieve your target compression ratio and ensure proper piston-to-valve clearance.
