    • Run Cooler with an External Oil Pump

      Moroso External Oil Pumps are available in single and two-stage variants that operate cooler than an internal pump and feature an external bypass for easy adjustment. Two-stage pumps allow scavenging oil from the oil pan with one stage and using the second stage to scavenge oil and/or pull vacuum from turbo or superchargers. External pumps help remove spark scatter and camshaft load associated with high-horsepower engines and come with all necessary fittings for installation.

      Step up your engine’s lubrication game with the Moroso External Oil Pump — a performance-driven solution built for high-RPM engines, forced-induction setups, and serious racing machines. If you’re ready to move beyond the limitations of a standard oil pump and want maximum control over your oil system, this is the upgrade you’ve been looking for.

      One of the standout advantages of an external oil pump design is that it runs cooler than stock internal units and incorporates an external bypass for easier adjustment and control. By removing the pumping load from the internal gears, you reduce camshaft and crank stress—especially important when you’re pushing high horsepower or dealing with extended track session heat.

      Whether you're constructing a dry-sump system, upgrading a wet-sump setup, or building a turbocharged monster, this external engine oil pump gives you the flexibility to tailor your oil flow, pressure, and plumbing for real performance. You’ll experience more consistent oil pressure, better engine protection under load, and fewer worries about oil starvation or heat-soak.

      Installation is straightforward for most performance engines: the pump mounts externally, uses large AN-style fittings, and eliminates complex internal pump clearance issues. From drag strip launches to road-course abuse, the results are real. You get an oil sump pump alternative that delivers serious benefits when your engine is under extreme demands.

      In short: if you want a high-quality, race-capable external oil pump that will perform when it matters most, this Moroso unit delivers. Make the investment, install it with confidence, and give your engine the lubrication system it deserves.
