Technical Description
This complete turbo oil and water 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 provides the external pressurized oil feed, gravity oil drain and water-cooling connections required for the upgraded turbo installation.
Converting from the factory K0422 turbocharger to a BorgWarner EFR unit changes the oil inlet, oil drain and coolant-port connections. The original K0422 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, a reinforced 3/4-inch NBR oil drain hose with CNC-machined aluminum flanges, and two -6AN PTFE braided water lines. The required engine, turbo and vehicle-side adapters complete the external oil and coolant plumbing.
Key Features
- Complete turbo oil feed, gravity-drain and water-line conversion for listed BorgWarner EFR applications
- EFR-specific oil inlet fitting without an additional external restrictor
- Flexible -4AN oil feed and two -6AN water lines with PTFE cores and stainless steel braid
- Reinforced 3/4-inch NBR drain hose with CNC-machined turbo-side and engine-side drain flanges
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.
