Built for the 1JZ and 2JZ Swap
The Moroso 20948 is an aluminum road race oil pan engineered specifically for Toyota 1JZ and 2JZ engine swaps that require a rear sump, wet sump configuration. Moroso part 20948 uses internal baffling to keep oil at the pickup during hard cornering and braking, which matters once these engines are pushed on track. At 5.75 inches deep with a 6 quart capacity, part number 20948 is sized to clear common swap chassis while still providing enough oil volume for sustained high-load driving.
Key Features
- Cast aluminum construction for reduced weight versus a steel pan
- Road race baffling to control oil movement under lateral and braking loads
- Rear sump, wet sump design built for Toyota 1JZ/2JZ swap applications
- 5.75 inch deep sump with 6 quart capacity
- Engineered specifically around the 1JZ/2JZ engine family rather than adapted from another pan
