I-Beam Connecting Rod Kit for Mini R56 Cooper S/JCW N14/N18

The CTS Turbo Mini R56 Cooper S/JCW connecting rods are engineered as a direct-fit upgrade for Mini Cooper models equipped with 1.6L N14/N18 engines, including John Cooper Works variants. CTS Turbo maintains rigorous quality control throughout the manufacturing process. The critical big and small end bores are precisely honed in-house using advanced equipment to meet exact specifications. Each connecting rod is then meticulously measured on a state-of-the-art Coordinate Measuring Machine (CMM) to verify all critical dimensions. Furthermore, all rods within a set are weight-matched to within a tight tolerance of +/- 1 gram to ensure optimal engine balance and performance. These connecting rods feature a tapered pin end and are constructed with genuine ARP 2000 rod bolts, known for their superior strength and reliability under demanding conditions. The product specifications include a center-to-center length of 138.55mm, a wrist pin diameter of 20mm, a big end journal width of 20.87mm, a big end journal diameter of 48mm, and rod bolt dimensions of 3/8″. Engine codes compatible with these connecting rods are N14B16, N18B16A, N18B16B, and N18B16C.
