Supertech Mini R56 N18 1.6T 77.00mm 10.5:1 CR Pistons - Set of 4 (Use w/GNH07700 ) (Excl Rings)

These Supertech pistons are forged from high-strength aluminum alloy, a material chosen for its excellent strength-to-weight ratio, which is crucial for high-performance engine builds. Each piston measures 77.00mm in diameter, designed to achieve a 10.5:1 compression ratio when paired with the specified GNH07700 connecting rods. This specific compression ratio is a notable choice for naturally aspirated or moderately boosted applications, offering a good balance between power output and reliability.

The forged construction means these pistons are significantly stronger and more durable than cast pistons. This makes them well-suited for engines that see demanding use, whether it's spirited driving or competition. The set includes four pistons, ready to be installed in your Mini R56 N18 1.6T engine. Keep in mind that these pistons are sold without rings, so you'll need to source those separately, ensuring they are compatible with the 77.00mm bore and the piston groove dimensions.

When rebuilding your engine, using pistons like these from Supertech ensures you're starting with a solid foundation. Proper installation, including ensuring correct piston-to-wall clearance and using the recommended connecting rods, is key to unlocking their full potential and ensuring long engine life. Always refer to the manufacturer's detailed installation instructions for precise specifications and procedures.
