Supertech Mini Cooper BMW B48 JCW 2.0T 16V 82mm 33.2mm CH 10.2:1 CR Piston - Set of 4 (Excl Rings)

This set includes four Supertech forged pistons, specifically made for the BMW B48 JCW 2.0T 16-valve engine. These pistons feature an 82mm bore and a 10.2:1 compression ratio, designed to replace your original equipment pistons when rebuilding or upgrading your engine. They come without piston rings, so you'll need to source those separately to complete the assembly.

Forged pistons are known for their strength and durability, making them a popular choice for performance builds or when dealing with higher cylinder pressures. The 10.2:1 compression ratio is a notable increase over stock, which can contribute to improved engine performance and responsiveness when paired with appropriate tuning. The 33.2mm compression height is also a critical measurement that ensures proper valve-to-piston clearance and correct deck height in the engine assembly.

When undertaking an engine rebuild with these pistons, it's important to ensure all supporting components are in good condition. This includes checking the connecting rods for straightness and ensuring the crankshaft is within specification. Proper balancing of the rotating assembly is also recommended for smooth operation and longevity, especially with performance-oriented components like these.
