Technical Description

Running a large-frame Garrett GT-Series turbo—GT37R, GT40R, GT42R, or GT45R—on your Nissan RB20DET, RB25DET, or RB30 engine?

These turbos are always mounted top mount, and demand a reliable, restricted oil feed to prevent over-oiling and bearing damage. Factory lines don’t fit or restrict properly for these turbos.

This turbo oil feed line kit includes a 2.0mm restrictor flange, 4AN pre-crimped PTFE braided line, and all required hardware to ensure precise oil flow and safe, bolt-on installation.

‣ Engine compatibility: RB20DET / RB25DET / RB30
‣ Turbo compatibility: GT37R / GT40R / GT42R / GT45R
‣ Top mount only setups
‣ Includes 2.0mm restrictor oil feed flange + gasket + bolts
‣ 4AN pre-crimped PTFE braided stainless steel oil line
‣ Engine-side fitting + copper crush washer included
‣ Designed for high-pressure, high-temperature applications
‣ Prevents over-oiling of journal bearing turbos
‣ Custom line lengths available
‣ In stock and ready to ship

Installing a GT37R to GT45R on your RB engine?
This feed kit is built to handle large-frame turbo oil demands, with precise restriction and complete fitment out of the box.
