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

Stage II pumps increase the overall flow by machining a deeper pocket into the oil pump and fitting larger gears in this pocket. This increases the strength of the pump, increases mid-range oil pressure, and increases the strength of the oil pump gears. The Stage II Pumps have these additional modifications: • Larger gears are fitted into the oil pump which increases mid range protection and insures compatibility with VVT. • The pump is shimmed increasing maximum warm pressure from 60 PSI to 70 PSI. All assembled billet pumps undergo the following: • Pump is completely taken apart, all parts under go ultrasonic cleaning, air blast, and hand inspection. • Pump is hand de-burred. • Our industry leading mirror finished gear set is used • Stainless Torx heads replace the stock fasteners • All fasteners are torqued to spec • Loctite applied to fasteners to prevent back out or loosening • Anaerobic sealant applied to critical areas to boost pump up speed and reduce aeration. • Assembly lubricant applied to all critical surfaces to get oil flowing fast on startup • Parts are blue printed and issued with specification sheet.
