TOMEI revolutionizes engine performance with its advanced Valve Guides crafted from Phosphor Bronze (Cn-Sn-P alloy), ensuring unparalleled tensile strength and superior heat transfer capabilities crucial for high-powered, high RPM engines. In the contemporary landscape of race engines demanding increased power at higher RPMs with leaner AFR mixtures, the valve train faces heightened heat stress, posing a risk of rapid deterioration. The Phosphor Bronze material, with its remarkably low friction, facilitates optimal clearances, effectively mitigating stress on the valve train. This results in a preventive measure against seizures and cracking under extreme stress loads. Specifically designed for Nissan Skyline R31 – RB20DET and Nissan Skyline R32 – RB20DET engines, TOMEI’s Valve Guides stand as a testament to cutting-edge engineering that ensures peak performance and durability in the most demanding conditions.
