Supertech Toyota 2JZ 86mm 34mm CH 86mm Stroke -7.2cc Dish 9.5:1 CR Piston - Set of 6 (Excl Rings)

If you're rebuilding the heart of your high-performance Toyota 2JZ engine, getting the right pistons is crucial. This set from Supertech is built for those looking to achieve a 9.5:1 compression ratio with an 86mm bore, perfect for many street and track builds. These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process makes them incredibly strong and durable, able to handle the higher cylinder pressures and temperatures common in modified 2JZ engines.

Each piston in this set features a 34mm compression height and a -7.2cc dish, which is what helps achieve that 9.5:1 compression ratio when paired with the correct cylinder head and deck height. The 86mm bore size is a common upgrade for the 2JZ, allowing for increased displacement over the stock bore. Remember that these pistons are sold as a set of six and do not include piston rings, so you'll need to source those separately. It's always a good idea to check your specific engine's requirements and consult with your machine shop to ensure these pistons are the right fit for your build goals.

When installing these pistons, ensure your cylinder block is properly machined to the 86mm bore size and that the connecting rods are prepared for the 34mm wrist pins. Proper balancing of the rotating assembly, including these new pistons, is also highly recommended for smooth operation and longevity. This set is a solid option for anyone looking to build a reliable and powerful 2JZ engine.
