The factory oil pump simply cannot deliver adequate volume and pressure at extreme engine speeds, leading to main bearing wear, catastrophic failures, and broken sintered-metal gears under high load. The Tomei High Volume Oil Pump (TB203A-NS05A) solves these critical weaknesses with a significantly larger, high-strength pump gear that provides substantially increased oil flow and a built-in external pressure adjuster for precise tuning.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThis pump is engineered to maintain consistent oil pressure even in highly modified RB engines pushing serious horsepower, dramatically improving reliability and longevity under demanding conditions. The robust construction addresses the stock pump’s weak points while delivering the volume needed to support aggressive builds without compromising the engine’s oiling system. An included gasket makes installation straightforward.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAt Terra Firma Automotive, we supply this genuine Tomei High Volume Oil Pump as a must-have reliability upgrade for serious RB26, RB25, and RB20 builders.
