What is the compression ratio with these pistons?

These Mahle pistons are designed to achieve a 9.5:1 compression ratio when used with the appropriate cylinder head and gasket combination for the VR38DETT engine.

What material are these pistons made from?

The pistons are constructed from 2618 aluminum, a well-known material for its strength and durability in high-performance engine applications.

Are these pistons coated?

Yes, the piston crowns feature a TBC (Thermal Barrier Coating). This coating helps to reflect heat away from the combustion chamber, which can reduce the risk of detonation and allow for more aggressive engine tuning.

Product Details

If you're building a high-performance VR38DETT engine for your Nissan GT-R, Mahle's MS GT-R Stroker Piston Set is a solid choice. This set is designed to help you achieve a larger displacement and improved compression for more power. The pistons feature a 95.51mm bore and a 94.4mm stroke, working with a 165.1mm connecting rod to create a stroker setup. This combination is key to increasing the engine's overall displacement and potential output.

Mahle uses 2618 aluminum for these pistons, a material known for its strength and durability under high stress, which is crucial for a performance engine. They come with a TBC (Thermal Barrier Coating) on the crown, which helps to reflect heat away from the combustion chamber, reducing detonation risk and allowing for more aggressive tuning. The pistons are designed for a 9.5:1 compression ratio, a popular target for many performance builds that balances power with pump gas compatibility. Each piston weighs 407g and includes a 23mm pin, ensuring they are robust enough for demanding use.

This set includes six pistons, enough for a complete VR38DETT engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful build, ensure you consult with your engine builder or refer to Mahle's detailed specifications for proper installation and compatibility with other engine components like rings and cylinder liners.
