Boundary Engineering

Designed in the USA, they are manufactured in house by master machinists. Designed to promote better flow, Boundary oil pumps produce more pressure earlier in the RPM range. These billet oil pumps protect your MX-5’s engine in extreme operating conditions, where horsepower and RPM limiters are greatly increased.

Founded in 2003, Boundary Engineering began manufacturing various automotive racing products. After much research and development, the first oil pump gears were launched in 2005. Boundary Engineering’s pump are now keeping thousands of street and race engines alive in Mazda MX-5s and other applications up to 550bhp/L.

Utilising start of the art simulation technology, the Mazda MX-5 billet oil pumps gears are designed to be indestructible. Tested under the most extreme applications, including debris strikes, vibration and unusual loads, they are essential in any raised RPM or high horsepower builds.

Standard Mazda MX-5 oil pump gears are sintered, which is an additive manufacturing process using powdered metal. This process can mean the gears can shatter, potentially destroying the engine. Billet oil pump gears are manufactured from a single piece of metal. Not only do they flow better and make more pressure, but they protect your engine from failure.
