BMW S14 Connecting Rod Set - ItalianRP IRPR020
The ItalianRP connecting rods are high-performance components designed specifically for the BMW M3's S14B23 2.5L 16-valve engine, which powered the E30 M3 from 1988 to 1991. Crafted in Italy, these rods are available in two distinct lines— Gold, and Platinum—each offering varying levels of strength and weight reduction to suit different performance needs. The Gold line employs 35NCD16 steel, offering higher strength and reduced weight. The Platinum line, made from the same 35NCD16 steel, undergoes additional treatments to achieve even greater strength and lighter weight, making it ideal for high-performance applications. These rods feature precise dimensions, including a big end diameter of 52.000 mm, a big end width of 24.000 mm, a pin diameter of 22.000 mm, and a center-to-center length of 144.000 mm, ensuring compatibility with OEM specifications. Whether you're building a street performance engine or preparing for track use, the ItalianRP IRPR020 rods offer a reliable and durable solution to meet your needs.
