TOMEI Valve Guide Set - Nissan RB26DETT

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research racing and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei’s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei’s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei’s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

Tomei made these Valve Guides from Phosphor Bronze (Cn-Sn-P alloy) since it has high tesile strength and superior heat transferring ability. They are important factors in high power and high RPM engines. Since race engines require higher RPM and leaner AFR mixtures these engines experience extreme heat conditions which will deteriorate valvetrain related components over time. The Phosphor Bronze material has exceptional lower friction characteristic and best possible clearances to reduce stress on the valvetrain prevent seizures and cracking under high stress loads.


NOTE: This kit comes with 24 valve guides for both intake and exhaust side.

Works only with RB26DETT Cylinder Heads!
