Part Number: BP-S1

Description: Boundary 91.5-00 Mazda Miata BP 1.8L Non-VVT I4 Oil Pump Assembly (w/o Crank Seal)

Details:

The Boundary BP oil pump starts with a fully torn down and inspected housing. This housing is then assembled with our billet oil pump gear and sealed. This pump also comes with the option for a high-flow billet backplate for those running over 7000 RPM consistently.

All assembled billet pumps undergo the following:

• Pump is completely taken apart, all parts undergo 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 a specification sheet.

Application:

• Mazda Miata 1991.5 – 2000

NOT RECOMMENDED FOR VVT MOTORS 2001-2005

NOTE: Customers will be responsible for providing their own OEM crank seal before installing.
