Nissan SR20DET + BorgWarner EFR Turbo Oil Drain Hose Kit

Proper Oil Drain Hose for BorgWarner EFR Turbo Upgrades

Upgrading your SR20DET (S13 / S14 / S15) to a BorgWarner EFR turbocharger requires a dedicated oil drain assembly—the factory SR20 drain hose and flange are not compatible with the EFR turbo’s drain design.

To ensure proper oil return and prevent leakage or oil-related issues, this Gryphontek high-temperature NBR turbo oil drain hose kit provides the correct flange, hose, fittings, and hardware needed for an EFR top-mount turbo setup.

Featuring a CNC-machined 6061-T6 aluminum flange, heat-resistant NBR hose, and durable steel fittings, this kit delivers a clean, dependable, and leak-free oil return path for both street and track SR20 builds running BorgWarner EFR turbos.
