Bery-Ring Set (Beryllium Copper)
The function required for valve seats is to maintain airtightness with the valve, and wear resistance is generally required. However, in an engine used at high rpm and high load, the cooling performance of the valve seat becomes very important, and it greatly affects the engine output. When the engine is running at high speed and under heavy load, the temperature around the cylinder head, especially around the combustion chamber, rises abnormally, so if the cooling performance is low, the knocking limit will not be high and high engine output cannot be expected. In racing engines, the key is how much the heat-sensitive valve seat ring can be cooled, and a method using a copper-based material with high heat dissipation for the seat ring has been adopted.
INCLUDES: Valve seat rings x16 (beryllium copper)
VEHICLE: Nissan Silvia S13 SR20DET 1989-1994
