Mazda OEM High-Volume Oil Pump for 1991-2005 Miata

After sifting through the Mazda Miata parts microfiche catalogs and seeing about a dozen different part numbers for oil pumps throughout the years, we got to the bottom of the story and found out that starting in 2001, Mazda began using a higher capacity oil pump to accommodate the new VVT systems on the engines. This "NB2" version of oil pump will provide increased oil pressure on a non-VVT car, which is valuable to just about everyone rebuilding an engine that plans to push it harder than the everyday commute would, which is why we recommend it for any engine build (greater oil pressure is ALWAYS a good thing to have!)
