Repl Cyl Sleeve Honda B18 3.180 Bore 3.475 OD

The Darton Sleeves Replacement Cylinder Sleeve for Honda B18 with a 3.180 bore and 3.475 OD is a crucial component for Honda engine builders and mechanics engaged in deep-block restoration or displacement increase projects. Cylinder sleeves are designed to restore worn or damaged bore walls to original specifications, allowing for the reconditioning of an engine block without the need for costly replacements.

This wet-sleeve design is specifically engineered for the B18 platform, commonly found in Honda Civic, Integra, and CRX applications. Darton Sleeves are manufactured from ductile iron, providing excellent bore roundness, tight tolerances, and thermal stability under load. The 3.180-inch bore diameter ensures compatibility with OEM pistons, while the 3.475-inch outer diameter allows for a secure press fit in the block, preventing distortion during operation.

This sleeve is particularly beneficial for engine builders looking to extend the life of race motors or for those installing turbochargers or superchargers. Proper installation requires honing, block preparation, and thermal-neutral assembly to ensure optimal performance and longevity.
