WG40 Compgate 40mm Ext Wastegate 14 PSI Black

The WG40 Compgate 40mm Ext Wastegate 14 PSI Black from Turbosmart USA is a precision boost control component engineered for turbocharged engine builders and performance tuners seeking reliable pressure regulation. This universal wastegate manages exhaust gas flow to maintain consistent boost levels, preventing overboosting that can damage engine internals while ensuring predictable power delivery. Built for applications ranging from street performance to track-focused builds, the Compgate delivers the dependability required in high-demand turbo systems.

The 40mm external wastegate features a 14 PSI spring calibration that regulates turbo boost by venting excess exhaust gases around the turbine wheel when pressure exceeds the set threshold. The black finish provides corrosion resistance in high-temperature underhood environments, while the 40mm diameter port accommodates substantial exhaust flow without flow restriction. Turbosmart's Compgate design incorporates precision engineering with clamps, flanges, gaskets, and hardware included, allowing straightforward installation and reliable seal integrity across multiple turbo platforms. The compact footprint—measuring 5.6 x 5.2 x 6.9 inches and weighing 2.86 lbs—fits tight engine bay layouts without sacrificing functionality.

This wastegate suits custom turbo builds, engine swaps, and performance upgrades where OEM boost control is inadequate or incompatible. Users benefit from the included hardware kit, which streamlines mounting and reduces assembly complexity. The universal design and modular clamp system accommodate various turbocharger configurations, making it ideal for builders working across multiple platforms. Installation requires exhaust manifold porting and proper wastegate plumbing integration; consult your turbo system documentation for specific routing requirements.
