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.

The crankshaft is, by far, the most massive moving part in your engine. There s a reason for that-the crankshaft is essentially ground zero for every bit of the torque your high-performance engine is capable of producing. It s pistons connected to connecting rods, which in turn are connected to the crankshaft, pounding down intermittently with incredible force. Meanwhile, at the back, the crank is connected to the clutch-and eventually the wheels-which are trying to resist acceleration. The same thing is going on at the front where the water pump, alternator, and other power-robbing assemblies are providing resistance. The result is a multitude of twisting forces applied to the crankshaft the entire time the engine is running. The stresses are multiplied in a racing situation in which the rpm levels can get quite extreme, and the frequent transitions from wide-open throttle to zero throttle only add to the equation. Factory crankshafts aren???t made with optimal strength in mind. Automotive manufactures must cut costs and materials and design crankshafts to withstand long periods of low rpm operation at idle or in stop and go traffic. The complete opposite of spirited driving.

Crankshafts that are purpose-built for racing are almost exclusively either forged or constructed from a piece of billet steel. Forging offers supplemental strength over cast pieces in addition to other advantages. Forgings produce a stronger grain structure and, are exceptionally strong. All Tomei Crankshafts are machined and balanced, preventing vibration and excessive engine wear.

    Mr. Seiichi Suzuki initially forged Tomei is a tuning factory for race cars back in 1968. From that day on, Tomei achieved excellent results in various motor sports categories. Tomei was then recognized for its technology, performance and reliability that we had cultivated into our own design products and had a large support base from motor sports end users and tuners.

    With the new market trends and demands, motoring enthusiasts wanted better performance to suit the new modern lifestyle. This trend helped set the stage where originality can play an active part in the motor sports scene and personal motoring lifestyle.
