Nissan SR20DET + Garrett G-Series G25 G30 G35 Turbo Oil Drain Hose Kit

Proper Oil Drain Flow for Garrett G-Series Turbo Conversion

Running a Garrett G-Series turbo (G25 / G30 / G35) on your Nissan SR20DET (S13 / S14 / S15) requires a reliable, unrestricted oil return path—something the aging OEM hose and random aftermarket fittings often fail to provide.

This Gryphontek NBR high-temperature turbo oil drain hose kit is built specifically for SR20DET turbo conversions using G-Series ball-bearing turbos, providing a clean, leak-free, gravity-fed return to the engine.

With a CNC-machined 6061-T6 aluminum drain flange, 45° steel elbow, and NBR heat-resistant drain hose, this kit ensures consistent oil evacuation whether you are running a stock mount manifold or a top-mount turbo setup.

Ideal for both street builds and high-boost SR20 track cars.
