Boundary BP-S3-SH2 High-Flow Oil Pump Assembly with Billet Gears

The Boundary BP-S3-SH2 is a precision-engineered oil pump assembly designed for Ford and Mazda BP engines from 1991.5 to 2005, including Mazda Miata and Ford Escort GT models. This high-performance assembly features machined billet steel gears that provide superior strength and durability compared to OEM powdered metal pumps, with yield strength approaching 110,000 PSI versus less than 6,000 PSI in stock applications.

Key Features:

• CNC-machined 4140 billet steel gears with mirror finish for maximum flow and reliability
• Housing machined for increased flow capacity and optimal gear clearances
• MartenWear treated gears tested to 15,000 RPM without wear for extreme durability
• Complete blueprinting with documented clearances and signed specification sheet included
• Ultrasonic cleaned, de-burred, and hand-inspected components
• Pre-lubricated assembly for fast oil flow on startup and reduced priming time
• Anaerobic sealant applied to critical areas to boost pump response and reduce aeration
• Compatible with all BP engine types including non-VVT and VVT applications

Each Boundary oil pump assembly undergoes rigorous quality control with precision measurements down to 0.0005 inches to ensure proper clearances. The assembly increases oil pressure by up to 25% and provides significantly more flow throughout the RPM range, making it ideal for high-performance street, track, and racing applications. Manufactured in-house at Boundary's Dallas, Texas facility using state-of-the-art CNC equipment. Note: Crank seal not included - customer must provide.
