Nissan RB20 RB25 RB30 Engine Block Oil Drain Fitting | 3/4" Barb

Designed for upgraded turbo setups, this 45-degree oil drain fitting allows you to connect a 3/4" hose directly to the engine block on Nissan RB20DET, RB25DET, and RB30 engines. The factory oil return barb is typically 5/8", which may not be compatible with high-flow turbo oil drains. This fitting solves the issue by providing a smooth 45° angle and a larger 3/4" barb for better oil evacuation. Ideal for custom turbo installations or when upgrading to a ball bearing turbo that requires higher oil flow. Made from durable mild steel with zinc plating for corrosion resistance.
