What material are these Mahle pistons made from?

These Mahle pistons are forged from 2618 aluminum. This material is chosen for its strength and ability to withstand high temperatures and pressures commonly found in performance engines.

What is the compression ratio and why is it important?

The pistons are designed to achieve an 8.5:1 compression ratio. This ratio is a key factor in an engine's power output and efficiency, and this specific ratio is often selected for turbocharged applications to balance performance with detonation resistance.

Are these pistons compatible with all RB26DET engines?

This piston set is specifically designed for the Nissan RB26DETT 2.6L engine. It is crucial to verify your engine's specifications and consult with a professional to ensure compatibility with your specific build.

Product Details

Mahle's MS Piston Set is built for the demanding RB26DET engine, starting with a precise 86.50mm bore size. These pistons are forged from 2618 aluminum, a strong material known for its durability under high stress and temperature conditions, making them a solid choice for performance builds. The 73.7mm stroke and 121.5mm rod length are key dimensions that work together to define the engine's displacement and power characteristics.

With a 21mm pin diameter, these pistons are designed to handle significant cylinder pressures. The 16.0cc dish volume contributes to an 8.5:1 compression ratio, which is a common target for turbocharged engines looking for a balance between power and reliability. Each piston weighs in at 366g, a carefully managed weight for optimal rotating assembly balance. This set includes six pistons, providing a complete solution for a 6-cylinder engine rebuild.

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, especially when dealing with performance engine components.
