Supertech Mini R56 N18 1.6T 77.50mm Bore 10:5 CR Pistons - Set of 4 (Use w/GNH07750) (Excl Rings)

Supertech is known for making well-built engine components for performance applications. If you're rebuilding the engine in your Mini R56 with the N18 1.6T engine, these forged pistons are a solid option to consider. They are designed to replace your stock pistons with a 77.50mm bore and a 10.5:1 compression ratio, which is a common target for mild performance builds or stock replacements where you want a fresh start with reliable parts.

These pistons are forged from high-strength aluminum, a process that makes them significantly stronger and more durable than cast pistons. This strength is crucial for handling the increased cylinder pressures and temperatures that come with a turbocharged engine like the N18. The 77.50mm bore size is specific to this application, ensuring a proper fit within the cylinder walls. It's important to note that these pistons are designed to be used with the GNH07750 connecting rods and do not include piston rings, so you'll need to source those separately to complete the assembly.

When installing these pistons, remember they are a critical part of your engine's rotating assembly. Proper balancing and careful installation are key to a long-lasting engine. Because these are forged pistons, they offer a good foundation for engines that see spirited driving or track use, providing peace of mind that your engine can handle the demands placed upon it. Please be aware that these pistons are not CARB approved and cannot be shipped to California.
