GFB (Go Fast Bits) - Performance Engine Components & Accessories

Founded in 1989 and based in Peakhurst, NSW, Go Fast Bits (GFB) designs and manufactures performance turbo parts in Australia under strict ISO‑9001 quality standards. Engineers and technicians with deep motorsport passion develop a comprehensive product lineup—including blow-off/diverter valves (DV+, Hybrid, VTA), boost and fuel pressure controllers, wastegates, lightweight pulleys, and short-shift kits—built for daily drivers and full‑race builds alike.

GFB is known for innovation and tuning performance: the Hybrid was the first 3‑mode BOV, while the DV+ introduced pilot‑operated precision for smoother boost transitions. The team maintains direct access to engineers for tech support, dyno data, and installation guidance. With the goal of “Performance Without Compromise,” GFB components prioritize fitment, durability, and real-world results—ensuring enthusiasts get powerful, reliable, and user-friendly upgrades straight from the source.
