The Tomei Beryllium Valve Seat Ring Set (part number TA310A-NS05A) is a complete intake and exhaust set manufactured from beryllium copper alloy and developed specifically for the Nissan RB26DETT in the Skyline R32, R33, and R34 GT-R.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eBeryllium copper offers significantly higher thermal conductivity than conventional cast-iron seats, allowing heat to transfer more effectively from the valve contact area into the cylinder head. This improved cooling helps protect against localized overheating, reduces the risk of seat cracking or recession under extreme conditions, and supports more consistent combustion chamber temperatures in high-output engines. The material also provides good wear and fatigue resistance, making it well suited to performance and competition applications where thermal management is a priority.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThese seats are an advanced upgrade typically installed during a full cylinder head rebuild and require proper machining for correct fitment. At Terra Firma Automotive, we supply this genuine Tomei Beryllium Copper Valve Seat Ring Set as a specialized component for serious RB26 builds. Whether the engine is being prepared for sustained high boost or high-RPM use, these seats deliver the heat-dissipation advantages associated with Tomei’s performance parts. Choose Terra Firma Automotive for authentic Japanese valvetrain components that support durable, high-output RB26DETT cylinder heads.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Tomei Beryllium Valve Seat Ring Set\u003c\/li\u003e\n\u003cli\u003ePart Number: TA310A-NS05A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eComplete intake and exhaust set\u003c\/li\u003e\n\u003cli\u003eMaterial: Beryllium copper alloy (BeCu)\u003c\/li\u003e\n\u003cli\u003eSuperior thermal conductivity versus stock seats\u003c\/li\u003e\n\u003cli\u003eImproved heat transfer into the cylinder head\u003c\/li\u003e\n\u003cli\u003eHelps reduce risk of seat cracking and overheating\u003c\/li\u003e\n\u003cli\u003eGood wear and fatigue resistance\u003c\/li\u003e\n\u003cli\u003eDesigned for high-load and high-RPM applications\u003c\/li\u003e\n\u003cli\u003eRequires professional machining for installation\u003c\/li\u003e\n\u003cli\u003eIdeal for performance and competition cylinder heads\u003c\/li\u003e\n\u003cli\u003eTrusted Japanese valvetrain engineering\u003c\/li\u003e\n\u003cli\u003eAvailable from Terra Firma Automotive\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tomei","offers":[{"title":"Default Title","offer_id":49497916080449,"sku":"TA310A-NS05A","price":1080.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1992\/7247\/files\/TA310A-NS05A.jpg?v=1728584387","url":"https:\/\/tfaspeed.com\/products\/tomei-berylium-valve-seat-ring-set-rb26dett-ta310a-ns05a","provider":"Terra Firma Automotive","version":"1.0","type":"link"}
