Garrett Turbochargers: Seven Decades of Boosting Innovation

Few names carry more weight in forced induction than Garrett. With roots stretching back to 1954, when the company delivered its first T-15 turbocharger to Caterpillar, Garrett has spent over 70 years refining the science of turbocharging. Today, as Garrett Motion, the brand supplies turbochargers to the world's leading automakers and simultaneously offers one of the most comprehensive performance turbo lineups available to enthusiasts and racers. When you browse the full turbocharger category, Garrett stands apart as a brand that bridges OEM engineering precision and top-tier motorsport performance.

A Turbo Lineup Built for Every Build

What makes Garrett's turbocharger catalog so compelling is its sheer breadth. The full performance lineup spans the GBC, GT, GTX, GTX Gen II, GTW, and G-Series, covering engine displacements from 1.4L to 12.0L and supporting power outputs ranging from 140 horsepower all the way to 3,000 horsepower — making it genuinely one of the widest ranges available from a single manufacturer.

• GT Series: The foundation of Garrett's performance heritage. These time-tested turbochargers have powered race cars, drag builds, and road cars across virtually every motorsport discipline.
• GTX Series: An evolution of the GT platform featuring improved compressor wheel designs manufactured from forged and machined billet aluminum, stepping up output potential while retaining familiar GT architecture. Select GTX units also include a fully machined speed sensor port for precision boost management.
• G-Series: Garrett's flagship performance turbocharger line, delivering the highest output from the smallest package available. The G-Series leverages advanced aerodynamic compressor and turbine wheel designs to maximize efficiency and spool speed.
• GTW Series: Designed with wider flow range in mind, the GTW uses a forged, milled compressor wheel with eleven blades and an Inconel turbine wheel for superior heat resistance — making it a strong choice for enthusiasts who want serious performance at an attainable price point.
• PowerMax: Garrett's direct-fit performance upgrade line. PowerMax turbochargers are engineered to increase engine performance while maintaining OEM installation specifications — bolt-on fitment with no fabrication required. They feature GTX Gen II compressor aerodynamics and high-temperature Mar-M alloy turbine wheels with twin-scroll stainless steel housings rated to withstand extreme heat.

OEM Roots, Motorsport Credentials

Garrett's authority in turbocharging isn't just a marketing claim. The brand supplies OEM turbochargers across a vast range of gasoline and diesel passenger cars and trucks, and its engineering teams operate at the intersection of OEM demands and motorsport extremes. Garrett also holds a patent on single-cartridge, dual ball bearing technology — a design that uses a single sleeve system with angular ball bearings on either end to dramatically reduce friction and improve spool response. This same engineering mindset carries over directly into their performance turbocharger products.

Garrett also offers Variable Nozzle Turbine (VNT) technology in its broader turbocharger portfolio, where turbine wheel exhaust flow control delivers higher torque, improved transient response, and cleaner combustion — a technology that reflects the brand's ongoing investment in efficiency-focused engineering.

Replacement and Remanufactured Options

Beyond performance builds, Garrett's aftermarket turbocharger catalog addresses OEM replacement needs with equal rigor. Replacement and remanufactured units are recalibrated and inspected to the same specifications as original new parts, covering applications from passenger cars to heavy-duty trucks. This makes Garrett a one-stop resource whether you're replacing a worn factory turbo or building a high-horsepower race engine from scratch.
