Toda B-Series Engine
One aspect that makes TODA different is that their B-Series product development started in 1992 while creating a racing engine for the Japanese Formula 4 series. Below are some pictures of the TODA F4 engine. Imagine it mounted North-South orientation in a Formula chassis. Also note the dry sump oiling system and billet oil pan. The advantage to the customer is that the same parts and materials that are used in professional racing engines are also offered to public customers. Sometimes the parts on the racing engines are the same parts TODA offers to the public (TODA B16A/B18C cam pulleys, timing belts, headgaskets, valves springs, and sports injection are the same ones as used on Formula 4 professional engines). Other parts like camshafts and pistons are more specific to F4 racing, and wouldn't translate well to a production car due to vehicle weight differences (F4 cars are much lighter than a DC2 or EK9), and powerband requirements. In those cases the camshaft and pistons specs are created for the production cars (DC2, EK9, etc), but the cores are the same as the racing engines (material core quality is key to durability).
