What is the compression ratio of these pistons?

These Manley pistons feature a 10.0:1 compression ratio. This is a common ratio for performance builds, offering a good balance between power and drivability.

What material are the pistons made from and why is it important?

The pistons are forged from a 2618 alloy. This material is chosen for its strength and ability to withstand high temperatures and pressures found in performance engines, making them more durable than cast pistons.

Are rings and connecting rods included with this piston set?

No, this set includes only the pistons and wrist pins. You will need to purchase compatible piston rings and connecting rods separately to complete your engine build.

About this part

Product Details

If you're rebuilding the engine in your Mitsubishi Evo VIII or IX, especially if you're aiming for more power or a more robust setup, a set of high-performance pistons is a critical component. This set from Manley Performance is built for the 4G63 and 4G63T engines, featuring an 86mm bore and a 10.0:1 compression ratio. These pistons are designed to handle the demands of modified engines, offering a solid foundation for your build.

Manley uses their signature 2618 alloy forgings for these pistons, which are known for being strong and reliable under high stress. They also come with premium chrome moly wrist pins, and for this specific set, they are Turbo Tuff (T/T) rated, indicating an even higher level of durability. The pistons have carefully machined cam and barrel skirt profiles that help them run smoothly and quietly while still generating significant power. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for better combustion efficiency and more power output. The unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, which is important for proper ring function.

This piston set is a popular choice among professional engine builders and tuners who need dependable performance. It's important to note that these pistons are not CARB approved and cannot be shipped to California. When planning your engine build, remember to factor in all the necessary components like rings, connecting rods, and bearings, as these are typically sold separately.
