• Any Honda/Acura chassis running a B-series engine swap (B16, B17, B18, B20 - all variants)

Fitment Notes

• This pan fits all Acura/Honda B-series VTEC and non-VTEC engine variants - use the stock oil pump and stock oil pump pickup (no pickup replacement required).
• Works with OEM exhaust manifolds and most aftermarket exhaust/header combinations without modification.
• For Acura Integra Type-R (B18C5) applications: the lower support bracket at the transmission inspection plate must be removed for proper fitment.
• Includes 1/2" NPT bungs for turbo/supercharger oil drain back and oil temperature sender - no welding required for forced induction setups.
• Gasket and installation hardware not included - use OEM B-series oil pan gasket or equivalent.
• Not compatible with Honda/Acura K-series, D-series, F-series, or H-series engines.

Features

• 6 trap doors and 2 internal baffles prevent oil starvation and maintain consistent oil supply to the oil pump pickup during hard cornering, braking, and acceleration events.
• Removable sump tray allows easy cleaning and inspection of baffle assemblies between race events without removing the entire oil pan.
• Kicked-out sump design pushes the oil reservoir further from the engine centerline, increasing effective oil capacity while maintaining proper ground clearance in most production chassis.
• 5.5 quart (approximately 1.5 quarts over stock) oil capacity provides increased oil volume for improved thermal buffering during sustained high-RPM operation.
• 6 inches deep - matches the stock oil pan depth profile to retain clearance for OEM and most aftermarket exhaust/header routing.
• Dual 1/2" NPT bungs pre-installed for turbo/supercharger oil drain return line and oil temperature sensor - eliminates the need for custom fabrication on forced induction builds.
• Magnetic drain plug captures ferrous metallic debris from oil - provides early warning of internal engine wear without requiring an oil filter cut.
• Fully fabricated from high-quality steel and hand-welded at Moroso's facility in Guilford, Connecticut.
• Black powdercoated finish provides superior corrosion resistance and a durable, professional appearance compared to the previous clear zinc finish.

Product Description

The Moroso 20910 is a road race baffled steel oil pan engineered specifically for Honda and Acura B-series engines - covering all VTEC and non-VTEC variants including the B16A1, B16A2, B16A3, B16B, B18A1, B18B1, B18C1, B18C5, and B20 family. Designed from the ground up for circuit racing, time attack, autocross, and high-performance street use, the 20910 addresses one of the most common failure points in aggressive B-series builds: oil starvation during sustained lateral G-loads, hard braking, or aggressive acceleration that can uncover the oil pump pickup in a stock pan. With 6 trap doors, 2 internal baffles, and a removable sump tray, the 20910 ensures consistent oil delivery to the pickup under any dynamic driving condition.

The kicked-out sump design expands the oil reservoir laterally, increasing capacity from stock to 5.5 quarts while preserving the 6-inch depth profile that allows the 20910 to work with OEM exhaust manifolds and most aftermarket header configurations without modification. The two pre-installed 1/2" NPT bungs eliminate a major fabrication headache on forced induction builds - one serves as the turbo or supercharger oil drain return, and the second accepts an oil temperature sender. The stock oil pump and pickup are retained, keeping installation straightforward and avoiding the need for additional hardware.

Fabricated from high-quality steel and hand-welded at Moroso's facility in Guilford, Connecticut, the 20910 is finished in Moroso's in-house black powdercoat process for long-term corrosion resistance. A magnetic drain plug comes pre-installed and captures ferrous metallic debris during oil changes - providing an early wear indicator at zero additional cost. The 20910 is widely used across the Honda performance community in EF/EG/EK Civics, EE/EF CRX builds, DA/DC Integras, and B-swap applications of all configurations. It is one of the most proven oil pan solutions in the B-series ecosystem and remains the benchmark for track-prepared Honda/Acura builds.
