Valve Guide Set for 1989-1990 Nissan Silvia / 180SX by Tomei
Tomei utilizes Phosphor Bronze (Cn-Sn-P alloy) to make their Valve Guides, for its highly tensile and superior heat transferring ability, which is vital in high power and high RPM outputting engines. Since race engines these days require more power at higher RPM use, these engines now experience more extreme heat conditions. These conditions will increase the deterioration rate on these valve train related components. The Phosphor Bronze material has exceptionally lower friction and the best possible clearances can be maintained, which will reduce the stress on the valve train assembly, prevent seizures and cracking under high stress loads.
When installing Tomei Type A valve springs in an RB26 and performing a three angle valve job, the stock spring load spec of 24kg is decreased to less than 20kg. By installing the Tomei Valve Spring Seats, the spring load can be brought back to tolerance to the 24kg range, enabling the engine to rev freely once again.
