Technical Description

Installing a Holset HX30, HX35, or HX40 turbo on your Nissan RB20DET, RB25DET, or RB30 engine?

These rugged HX turbos thrive on steady oil flow, but when fitted on a top mount manifold, the OEM feed line simply won’t reach—and may cause leaks or routing issues.

This turbo oil feed kit includes a high-temp 4AN braided PTFE line, engine-side adapter, and the correct turbo-side 4AN fitting to get you running safely with zero oil restrictor required.

‣ Designed for RB20DET / RB25DET / RB30 engines
‣ Compatible with Holset HX30 / HX35 / HX40 turbos
‣ Built for top mount turbo installations
‣ No oil restrictor required for these turbos
‣ Includes 4AN pre-crimped PTFE braided stainless steel oil line
‣ Engine-side adapter + copper crush washer included
‣ Turbo-side 4AN fitting included
‣ Heat- and pressure-resistant for reliable performance
‣ Custom line length available
‣ In stock and ships fast

Upgrading to a top mount Holset turbo?
This kit provides precise fitment, correct oil delivery, and reliable performance—with no guesswork or extra parts needed.

📦 All kits are stocked and ready to ship.
