High-Flow Oil Drain System for Holset HX30 / HX35 Miata Turbo Builds

When installing one of these turbos on a Mazda MX-5 Miata MK1 (NA), MK2, or MK2.5 (NB), a high-flow oil drain system is mandatory—N/A Miata engines do not include turbo drain provisions. Using restrictive aftermarket flanges or small-diameter hoses can quickly lead to oil pooling, smoking, and bearing damage.

This Gryphontek High-Flow turbo oil drain hose kit solves that problem with a 6061-T6 CNC-machined drain flange featuring an enlarged bottom drain port, combined with a 19mm inner diameter NBR oil drain hose engineered specifically for the higher return volume of HX30/HX35 turbos.

Built for boosted Miatas targeting strong midrange torque, big power, and long-term turbo reliability.
