Nissan SR20DET + Garrett T3 T4 Turbo Oil Drain Hose Kit

High-Flow Oil Drain System for Garrett T3 / T4 Turbo Upgrades

When upgrading your SR20DET (S13 / S14 / S15) to a Garrett T3 or T4 turbocharger, a high-flow oil return system is essential. Many aftermarket flanges use restrictive, undersized drain ports that can cause oil backup inside the CHRA—leading to smoking, leakage, and premature turbo wear.

This Gryphontek High-Flow NBR Turbo Oil Drain Hose Kit features a 6061-T6 drain flange with an enlarged bottom drain port for improved flow, paired with a large-diameter oil-resistant NBR hose to ensure fast, unrestricted gravity-fed drainage for T3/T4 turbo setups.

Designed specifically for SR20DET turbo conversions, it eliminates the bottlenecks and fitment issues common with universal aftermarket drain parts.
