Product Description

The **Boundary BP-OPG-NON-VVT** is a billet oil pump gear set designed for the Mazda/Ford BP 1.6 L and 1.8 L engines that do **not** have VVT (Variable Valve Timing). Constructed from chromoly billet and hardened using Boundary's ColdFlow process, this gear set is built for strength, durability, and reliable oil delivery under performance conditions.

With a mirrored finish and precisely ground gerotor gears, this upgrade reduces internal losses and improves lubrication efficiency, making it ideal for high-RPM engines, motorsport use, or any build where longevity and oil pressure stability are critical. It fits directly into the original BP-series oil pump housing, offering a straightforward, high-quality upgrade over the stock OEM gears.
