GARRETT
Garrett Motion: The Evolution of Boost and Peak Performance Dominance
In 2026, Garrett continues to set the benchmark in turbocharging technology. The launch of the G-Series II (Gen 2) marks a significant milestone, delivering up to 10% more compressor flow than its predecessor within the same physical footprint. Whether for Le Mans-winning endurance or setting records at local drag strips, Garrett is the absolute choice for high-performance builds ranging from BMW M to heavy-duty motorsport icons.
ATOMIC-SHOP Ukraine is an official Garrett distributor. We provide expert selection and supply of everything from the compact GBC series for small displacements to the legendary G57 frame units capable of 3000+ HP.
G-Series II (Gen 2): Engineering the Future of Flow
The 2026 flagship line features optimized compressor aerodynamics that push the boundaries of what’s possible in small and large frame turbos:
- Enhanced Aero: The Gen II fully-machined forged compressor wheels provide higher efficiency at peak pressure ratios, allowing for more power with lower intake temperatures.
- Mar-M Turbine Alloy: Rated for exhaust temperatures up to 1050°C, providing unmatched durability for high-output gasoline applications.
- Seamless Integration: G-Series II CHRAs are outline interchangeable with G-Series Gen I housings, offering a direct performance upgrade path for existing users.

The GBC series is Garrett’s answer for the "Club" enthusiast. These journal-bearing turbochargers offer Garrett reliability at a cost-effective price point, making them perfect for budget-conscious builds and powersports applications.
- Integrated Solutions: Features internally wastegated housings for easy installation.
- CFD Optimized: Even the entry-level GBC line utilizes forged, fully-machined compressor wheels for reliable performance.
FAQ: ATOMIC-SHOP Technical Expertise on GARRETT
What does the Garrett nomenclature (e.g., G30-660) stand for?
The first number, "30," identifies the frame size, while "660" represents the maximum horsepower rating the turbocharger can achieve under optimal conditions. This is currently the most intuitive naming system in the performance industry.
Is it necessary to install a Turbo Speed Sensor?
For high-performance builds pushed to their limits—absolutely. It allows you to monitor shaft speed and prevent an "overspeed" condition, which can lead to catastrophic compressor wheel failure. All modern Garrett G-Series units come pre-machined with a dedicated port for this sensor.
Ball Bearing vs. Journal Bearing: Which one should I choose?
For superior transient response (spool) and extreme thermal loads, the dual ceramic Ball Bearing system is the gold standard. However, for budget-conscious builds or daily drivers
