Garrett GVW-45 Wastegate Kit 45mm

Garrett GVW-45 Wastegate Kit delivers precision boost control through CFD-optimized flow design. This 45mm external wastegate regulates turbocharger shaft speed by venting exhaust gas around the turbine, maintaining consistent boost pressure across your power band. Built from high-temp stainless steel rated to 1050°C, the GVW-45 handles extreme exhaust temperatures while advanced thermal optimization protects the diaphragm for extended durability. The innovative cap design simplifies spring changes and full serviceability; critical for tuners who demand reliability. Direct replacement for TiAl MVR, Turbosmart 45mm, and Precision 46mm gates. Outline and flange compatible with competitor units, but engineered to outflow them. Spring pressure range of 0.2–1.7 bar (3–25 psi) provides tuning flexibility for street and competition applications. Specifications: 1.47 kg valve mass, M10x1.0 air port, M8x1.0 liquid port, 4 kg total weight. Purpose-built for serious turbo builds where boost control precision matters.
