Proven Power. Legendary Reliability.

T3/T4 Turbochargers Built for the Grassroots Racer or Steet Car.

As we continue to push limits and break barriers, we’ve seen a growing demand for turbochargers that deliver reliable power without compromise at a Grassroots price. That’s why we’re going back to a proven formula: the T3/T4 turbocharger—a workhorse with decades of success under its belt.

Whether you're building a street car, a weekend warrior, or you're the underdog aiming high, the T3/T4 platform offers unmatched versatility.

With over 29 years of experience, Work Turbochargers has been creating hybrid designs, performance upgrades, and reliability innovations.

Our journey started with the Buick Grand National, a legend that made the T3/T4 combo a household name in turbocharging.
