Supertech Toyota 2JZ 86.5mm (+0.5) 86mm Stroke -7.2cc Dish 9.5:1 CR Piston - Set of 6 (Excl Rings)

Supertech is known for making well-built internal engine components, and this set of forged pistons for the Toyota 2JZ engine is a prime example. If you're rebuilding the heart of your 2JZ, these pistons are designed to handle increased performance demands. They feature an 86.5mm bore, which is a +0.5mm overbore from the stock 86mm size, and are built for an 86mm stroke. The dish volume is -7.2cc, resulting in a 9.5:1 compression ratio, a popular choice for a balance of power and pump gas drivability in modified 2JZ builds.

These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that see hard use or have been modified with forced induction. The 9.5:1 compression ratio is a solid option for many builds, offering improved response over lower compression setups while still being manageable with premium pump gas in many applications. 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.

When planning your 2JZ build, it's important to note 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 procedures.
