What is the purpose of the 0.5mm oversize bore size?

The 0.5mm oversize bore size is used to account for wear in the engine's cylinders or to achieve a specific bore size for a performance build. It means the piston is slightly larger than the standard size and requires the cylinder bore to be machined to match.

What is the benefit of the moly skirt coating?

The moly skirt coating on these pistons helps to reduce friction between the piston skirt and the cylinder wall. This can lead to improved performance and increased durability by minimizing wear.

Are these pistons suitable for high-performance applications?

Yes, these pistons are forged from 2618 alloy and feature design elements like precise ring lands and cam/barrel skirt profiles, which are common in high-performance engine builds. They are designed to handle increased stress and power output.

About this part

Product Details

Manley Performance is well-known for making strong engine components for serious builds. This single forged piston is part of their Platinum Series, designed for engines that need more than stock parts can offer. It's an 87.0mm bore piston, sized 0.5mm over, and features a dish top that works with 8.5:1 to 9.0:1 compression ratios, making it a solid choice for rebuilding or upgrading engines in a range of vehicles like the 1993-1999 Mitsubishi Eclipse, 1995-1999 Mitsubishi Galant, and the 2003-2006 Mitsubishi Lancer.

These pistons are forged from 2618 alloy, which is a strong material chosen for its ability to handle high performance demands. Manley also applies a moly skirt coating on select part numbers like this one, which helps reduce friction and wear on the cylinder walls. The ring lands and grooves are machined to strict standards to ensure a good seal with the piston rings, helping to get more power out of every combustion cycle. The cam and barrel skirt profiles are also carefully shaped to work smoothly with the cylinder walls, contributing to both power and longevity.

When you're putting these pistons in, remember that they are sized 0.5mm oversize. This means the cylinder bore needs to be honed to match this size. It's a good idea to check the manufacturer's installation instructions for specific details on ring gap and assembly.
