Nissan 300ZX Z32 VG30DETT + Garrett GT25R GT28R Turbo Oil Feed Line Kit｜4AN Braided

Upgrading your Nissan 300ZX Z32 VG30DETT to Garrett GT25R or GT28R ball-bearing turbos requires a properly designed turbo oil feed line kit to maintain optimal lubrication and prevent turbo seal failure.

This 4AN PTFE Teflon stainless-braided oil feed kit by Gryphontek is engineered to handle the higher oil flow precision that ball-bearing turbos demand.

It replaces restrictive or outdated OEM lines with pre-crimped, high-pressure braided hoses and a 1.0 mm restrictor fitting, ensuring correct oil pressure balance across both turbos—protecting your investment and improving long-term turbo reliability.

Ideal for bolt-on GT25R / GT28R upgrades, this kit provides everything needed for a clean, professional installation without custom machining or additional fittings.
