LS LS1 1/8 NPT Turbo Oil Supply Port Adapter

The LS LS1 1/8 NPT turbo oil supply port adapter from ICT Billet is a precision engineered component designed for LS-series engine builders and turbocharger installers who demand reliable oil delivery to their forced-induction systems. This adapter bridges the gap between your engine's factory oil galley and turbo charger systems, providing a secure 1/8 inch NPT female port connection that integrates seamlessly into high-performance engine modifications. Whether you're building a street-driven twin-turbo LS or a competition engine, this adapter eliminates guesswork and ensures proper oil flow to critical turbo bearings.

Manufactured from lightweight aluminum with a natural finish, the LS LS1 1/8 NPT turbo oil supply port adapter features a robust 1/2 inch thick construction that withstands the pressure and temperature cycling inherent to turbocharged engine operation. The 1/8 inch NPT female port threads accept standard turbo oil supply fittings, allowing you to establish a clean, direct connection to your turbocharger's inlet without adapter stacking or mismatched port sizes. Included hardware and O-ring sealing components ensure leak-free operation at idle and under full boost, protecting your turbo investment from oil starvation and contamination that can result from improper feed-line plumbing.

LS engine enthusiasts upgrading to turbocharging—particularly those working with LS1, LS2, LS3, and other factory or aftermarket LS platforms—will find this port adapter essential for clean, code-compliant oil feed installation. Installation requires minimal machine work and integrates directly into existing engine block galleries, making it ideal for builders who prioritize reliability over complexity. The compact 2.9 x 0.75 x 3.7 inch profile fits tight engine bays and turbo manifold configurations, and the minimal 0.12 lb weight adds negligible mass while solving a critical plumbing challenge in modern LS turbo conversions.
