Moroso Lotus/Toyota 2GR-FE/Z Road Race Baffled Wet Sump 6.25qt Stock Depth Aluminum Oil Pan - 20971 - MOR20971

The Moroso 20971 Road Race Baffled Wet Sump Oil Pan is a purpose-built aluminum oil pan engineered specifically for the Toyota 2GR-FE/Z engine as used in Lotus applications. Designed for the rigors of road racing and high-performance driving, this 6.25-quart, stock-depth pan delivers race-proven oil control without requiring chassis modifications or a dedicated dry-sump system. If you're building or upgrading a track-focused Toyota 2GR-powered Lotus and need reliable oiling under sustained cornering loads, this is the oil pan the serious motorsport community reaches for.

Key Features & Benefits

• Race-Proven Trap Door Assembly: Moroso's trap door mechanism prevents oil starvation during aggressive braking, acceleration, and high-G cornering — situations where the factory pan can allow oil to slosh away from the pickup and cause catastrophic engine damage.
• Removable Anti-Slosh Baffle: Keeps oil contained in the oil pump pickup area during both road racing and drag racing events, ensuring the pump always has a reliable oil supply regardless of lateral or longitudinal G-forces.
• Baffled Wet Sump Design: Retains the simplicity and weight efficiency of a wet sump system — no external reservoir, no additional pump, no complex plumbing — while delivering oiling security well beyond what a stock pan can provide at the track.
• Stock-Depth Fitment: The pan is designed to match the stock depth profile, which means it installs without requiring subframe modifications, custom crossmember clearance work, or ride-height compromises — a significant advantage on Lotus chassis that are already tightly packaged.
• 6.25-Quart Capacity: An increased oil capacity over the factory pan helps manage oil temperatures during sustained high-RPM track use, providing a larger thermal reservoir and more oil volume in circulation.
• Aluminum Construction: Lightweight aluminum keeps the pan from adding unnecessary weight to the drivetrain, contributing to the low unsprung and rotational mass priorities of a track build.
• Moroso Engineering Pedigree: Moroso is a long-established name in American motorsport oiling technology, and this pan carries their race-proven design philosophy developed for competition applications.

Fitment

This oil pan is designed to fit vehicles equipped with the Toyota 2GR-FE or 2GR-FZ engine in Lotus applications. The product name references the Toyota 2GR-FE/Z engine family as installed in Lotus platforms — most notably Lotus models that received Toyota V6 powerplants as part of their powertrain lineup. If you are unsure whether your specific Lotus model year or variant uses the 2GR-FE or 2GR-FZ, it is strongly recommended to verify your engine code before ordering, as this pan is engineered around that specific engine architecture. This pan is not a universal-fit item and is not intended for other Toyota 2GR applications (such as Camry, Sienna, or Highlander) where the chassis packaging and pickup geometry differ. Contact ThreePiece.us fitment specialists to confirm compatibility with your exact build.

Frequently Asked Questions

Does this oil pan require any chassis modifications to fit a Lotus with the 2GR engine?

Because Moroso designed the 20971 to match the stock depth of the OEM pan, it is intended to fit within the existing chassis clearances of 2GR-powered Lotus applications without requiring subframe or crossmember modifications. That said, every build is different — if your car has been lowered significantly or has aftermarket suspension components that affect pan clearance, contact our team before ordering to confirm fitment.

What makes this better than the stock Toyota 2GR oil pan for track use?

The factory pan is designed for street driving, where oil movement is relatively mild. On a road course, sustained high-G cornering, hard braking zones, and aggressive acceleration can push oil away from the pickup tube, leading to momentary oil starvation — a potentially engine-destroying event. Moroso's trap door assembly and removable anti-slosh baffle are specifically engineered to keep oil at the pickup under those conditions, which is why this pan is a popular upgrade for 2GR Lotus track builds.

Is this a dry-sump or wet-sump system?

This is a wet sump system — oil is stored in the pan itself, just as in a stock setup. You do not need an external oil reservoir, additional scavenge pump, or extra plumbing. This makes it a much simpler and more cost-effective upgrade path than converting to a full dry-sump system, while still providing significantly improved oil control over the factory pan.

Can I get help confirming this fits my car before I order?

Absolutely. ThreePiece.us offers expert fitment support — call our team at 813-535-5801 or reach out via email at sales@threepiece.us. We can help verify that MOR20971 is the correct oil pan for your specific engine code, model year, and build configuration before you commit to the purchase.
