Pump Assembly Mazda/Ford BP I4 1.6L ALL TYPES 91.5-05 Escort GT Mazda Billet Gear High Flow

The Boundary Engineering BP-S2 is a high-volume oil pump designed for the 1991.5-2000 Mazda Miata (non-VVT) and 1990-1991 Mazda Miata (short nose crank, 1.6L engine). It utilizes a machined factory housing to accept deeper VVT gearsets and increases oil pressure. The pumps are built to the 1991.5-2000 size and volume specifications. All assembled pumps undergo thorough inspection, cleaning, de-burring, and feature mirror-finished gear sets, stainless Torx head fasteners torqued to spec with Loctite, and anaerobic sealant for optimal performance. Assembly lubricant is applied to critical surfaces for fast oil flow on startup.
