High-Flow Oil Drain System for T3 / T4 Miata Turbo Conversions

When installing a Garrett T3 or T4 turbocharger on a Mazda MX-5 Miata MK1 (NA), MK2, or MK2.5 (NB), a proper high-flow oil drain system is essential.
The factory N/A engine provides no turbo drain fittings, and many aftermarket drain flanges use small, restrictive outlet ports that can cause oil to back up inside a T3/T4 turbo—especially under boost.

This Gryphontek High-Flow Turbo Oil Drain Hose Kit solves that issue with a 6061-T6 CNC-machined drain flange featuring an enlarged bottom drain port, paired with a large-diameter NBR return hose engineered to handle the increased oil volume typical of T3/T4 turbos.

Designed specifically for Miata N/A → Turbo conversions using larger-frame Garrett turbos, this kit ensures clean, gravity-fed drainage for both street and high-power builds.
