Upgrading your Mazda MX-5 Miata MK1, MK2, or MK2.5 with a Garrett GT25R, GT28R turbocharger demands precise oil pressure management.
Ball-bearing GT turbos require a restricted oil supply to maintain optimal lubrication without overwhelming the bearing housing.
This 4AN PTFE Teflon stainless-braided turbo oil feed line kit is purpose-built for Garrett GT-series ball-bearing turbos, featuring a 1.0 mm restricted adapter fitting with copper crush washer.
It ensures clean, consistent oil flow to the turbo while preventing over-oiling—a common cause of premature seal failure.
Designed for N/A-to-turbo Miata conversions, this kit provides a complete, leak-free oiling path that’s easy to install and built to last under boost.
