Moroso B Series Baffled Oil Pan for Civic/Integra

Moroso B-Series Baffled Oil Pan - Honda/Acura B-Series (Aluminum Drag / Steel Road Race)

This is a fully fabricated, baffled Moroso oil pan for the Honda/Acura B-series, built to keep oil over the pickup when the stock pan can't. The factory pan has minimal baffling, so under hard launches or sustained cornering the oil moves away from the pickup and you lose pressure right when the engine needs it. Moroso fixes that with internal baffling and trap doors. This page offers two versions, an aluminum pan for drag racing and a steel pan for road racing, so you can match the pan to how you run the car.

Choose Your Pan: Drag or Road Race

• Aluminum (Drag Race): fully fabricated aluminum with a kicked-out sump and integrated trap-door baffling. It's the lighter option, set up for straight-line launches. 5-quart capacity, 5-5/8" deep. Includes a hardware kit with hex-drive studs and serrated-face flange nuts.
• Steel (Road Race): fabricated steel finished in black powder coat by Moroso, with far more oil control for the sustained lateral loads of road racing: a removable anti-slosh baffle, five trap doors, and two sump baffles. It also has a kickout for extra capacity. 5.5-quart capacity, 5-1/16" deep. Steel also handles road-course abuse and curbing better than aluminum. Uses your stock oil pump and pickup.

Short version: the aluminum pan is lighter and built for the drag strip, while the steel pan has the heavier baffling and durability road racing demands.

Steel Pan Fitment Notes - Read Before You Order

The steel road race pan is a direct replacement across the B-series lineup (JDM or USDM): B16A (all variants), B16B, B17A, B18A/B (all), B18C/C1/C4/C5 (all variants), B20A/B/Z (all variants), LS/VTEC, and B20/VTEC. The stock oil pickup is compatible in most cases, but there are two cases to check:

• LS/VTEC: a B18C/C1/C5 oil pickup is required if you're adapting a B18C girdle. If you're keeping a B18A/B girdle and its oil pickup, you don't need it.
• B20/VTEC: a B18C/C1/C5 oil pickup is required if you're adapting a B18C girdle. If you're running a B20x girdle and its oil pickup, you don't need it.
• Type-R: because of the kickout, the Type-R requires the non-Type-R two-piece lower transmission brace.

Aluminum Pan Fitment

The aluminum drag pan fits Acura VTEC and non-VTEC B-series and the Honda 1.6L B16A3.
