About this part

Product Details

Starting with the 22.5mm wrist pin diameter, these Manley H-Beam connecting rods are built for the demanding MZR 2.3L DISI Turbo engine found in the MazdaSpeed 3. When you're pushing the limits of your engine, especially with forced induction, the connecting rods are a critical component that needs to handle significant stress. Manley has a long-standing reputation for making well-built internal engine components, and this H-Beam set continues that tradition.

These rods are finished to exacting tolerances, meaning the dimensions are precisely controlled to ensure they fit and function perfectly within your engine. Manley pays close attention to every detail, from the final hone size to the thread quality on the rod bolts, and even the bend and twist of the rod itself. This meticulous approach ensures you're getting a solid, reliable part that can handle the increased cylinder pressures and forces that come with a performance turbo engine. You also have the flexibility to choose between ARP 8740 or ARP 2000 bolts, depending on your specific build requirements and desired strength level.

This set includes all the connecting rods needed for your engine. If you're rebuilding the bottom end of your MazdaSpeed 3 or looking to upgrade for more power, these Manley H-Beam rods are a popular choice for their balance of strength, precision, and value.
