Boundary HIGH FLOW Oil Pump W/Billet Gears for 1991.5-2005 Miata

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.

• Industry leading mirror finished gear set are instaled

• 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.
