Ext Oil Pump 2-Stage Tri-Lobe LHS FP Drive

The Ext Oil Pump 2-Stage Tri-Lobe LHS FP Drive by MOROSO is an essential upgrade for serious engine builders and performance enthusiasts pushing high-horsepower applications. This external oil pump is engineered for engine configurations where increased oil volume and pressure delivery are critical to durability and reliability. Whether you're running a naturally aspirated stroker, a turbocharged build, or a race-prepared power plant, this pump addresses the oil starvation issues that plague stock and modified lubrication systems under extreme load and high RPM operation.

Built by MOROSO with a proven two-stage tri-lobe rotor design, this pump delivers superior flow characteristics and consistency compared to single-stage alternatives. The tri-lobe geometry provides smoother, more uniform oil delivery across a wider RPM band, reducing pressure spikes and cavitation noise while maintaining peak flow when you need it most. The left-hand shaft (LHS) orientation and FP drive coupling ensure compatibility with common racing and modified engine configurations, allowing for flexible installation in tight engine bays or custom frame setups. The compact external design—measuring 10.8 x 10.8 x 14.8 inches and weighing just 7.815 lbs—minimizes parasitic drag while offering straightforward bolt-on installation without requiring internal engine modifications.

High-RPM drag racers, bracket racers, and road-course competitors depend on the Ext Oil Pump 2-Stage Tri-Lobe LHS FP Drive to prevent catastrophic bearing damage and oil pressure loss under sustained boost or sustained rpm loads. Street performance builders benefit equally, gaining the margin of safety needed when combining aggressive cam profiles, supercharging, or turbocharging with extended track sessions. Installation is straightforward for technicians with experience in external pump systems; verify that your engine block accepts FP drive coupling and confirm left-hand rotation is correct for your specific application before ordering.
