What is the purpose of the -1.5cc dome volume?

The -1.5cc dome volume is a specific design feature that helps builders achieve a particular compression ratio in their engine. This is crucial for tuning engine performance and efficiency based on the cylinder head volume and gasket thickness used in the build.

Why is this piston not CARB approved?

This piston is not CARB (California Air Resources Board) approved, meaning it does not meet California's emissions standards. As a result, it cannot be legally shipped to or installed on vehicles registered in California.

What makes forged pistons different from cast pistons?

Forged pistons are made from a solid block of aluminum that is heated and hammered into shape, resulting in a stronger and more durable component. Cast pistons are made by pouring molten aluminum into a mold, which is generally less strong and more prone to failure under high stress.

Product Details

This Wiseco custom piston features a -1.5cc dome volume, a specific design choice for builders aiming for precise compression ratios in their Mitsubishi 6G72 engines. The 1.250-inch pin diameter and 3.6024-inch bore size are critical measurements for ensuring a proper fit and function within a custom-built engine. When you're assembling an engine from the ground up or modifying an existing one to meet specific performance goals, details like dome volume and pin size make a significant difference in how the engine performs and lasts.

Wiseco is known for well-built forged pistons, and this single custom piston is no exception. Forged construction offers improved strength and durability compared to cast pistons, making it a solid option for engines that will see demanding use. The -1.5cc dome shape is carefully crafted to work with specific cylinder head volumes and gasket thicknesses, allowing you to dial in your desired compression. This level of customization is key for enthusiasts looking to optimize their engine's power output and efficiency for unique applications.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and consult with a professional if you have questions about how this piston will integrate into your specific setup.
