Technical Description
This complete turbo oil feed and return line kit is designed for Mazdaspeed 3, Mazdaspeed 6 and Mazda CX-7 models equipped with the 2.3L MZR DISI Turbo engine and converted to a compatible BorgWarner EFR 6258, 6758 or 7163 turbocharger. It replaces the external pressurized oil-feed connection and gravity oil-return assembly required for the upgraded turbo installation.
Converting from the factory K0422 turbocharger to a BorgWarner EFR unit changes both the oil-inlet connection and oil drain flange pattern. The original K0422 oil pipes are not designed to connect directly to the EFR center housing, requiring compatible fittings, drain flanges and flexible line routing for the conversion.
This GryphonTek kit uses a -4AN PTFE braided oil feed line with an EFR-specific non-restricted turbo-side fitting. The return side uses a reinforced 3/4-inch NBR hose with CNC-machined 6061-T6 aluminum turbo-side and engine-side drain flanges, providing a flexible gravity-return path from the turbocharger to the engine.
Key Features
- Complete turbo oil feed and gravity-drain conversion for listed BorgWarner EFR applications
- EFR-specific turbo-side oil fitting without an additional external restrictor
- Flexible -4AN PTFE braided feed line and reinforced 3/4-inch NBR drain hose
- CNC-machined EFR turbo-side and thick-profile engine-side drain flanges with installation hardware
Installation Note
This kit uses a thick-profile engine-side oil drain flange. The included extended engine-mount bolts must be installed in place of the shorter factory bolts to provide the required clearance and thread engagement. Do not reuse the shorter factory bolts with the thick-profile flange.
