Boundary Assembled Oil Pump for Mazda MX-5 NA NB

This is a complete assembled oil pump with billet gears to suit the 1991.5 to 00 engines (1.6 and 1.8) as a direct bolt-on, it is not suitable for the VVT engine – the high flow assembled pump is what you need for that, these are considered stage 1 pumps;

Stage one pumps utilise a factory housing and have our gear set placed inside in order to strengthen the pump.

  1. All parts undergo ultrasonic, air blast, and hand inspection.
  2. The gear set is cut in-house from 4140 Chromoly steel billet.
  3. Parts are blueprinted and issued with a specification sheet.

A must-have upgrade for any MX5 looking to run either a higher rev limiter or higher power. A good rule of thumb is anything over 300 horsepower you really should be looking at these gears. Shock loading causing by boost cut or RPM limit can shatter the OEM sintered oil pump gears causing complete engine failure.

Consider it pretty required insurance if you’ve just built a forged engine with new pistons, rods, bearings – you wouldn’t want all that to be ruined by an oil pump failure.

The sintered gears inside of a stock oil pump assembly are only rated to about 6KSI of stress before shattering. These gears provide a serious structural upgrade to 90Ksi steel.
