The Garrett PowerMax™ Stage 1 GT2260S is the definitive turbocharger upgrade for the 2.0L VAG EA888 Gen 3 engine. Unlike hybrid turbos that use modified stock housings, the PowerMax™ is a clean-sheet design from Garrett, engineered to support up to 485 BHP. This bolt-on solution provides a massive increase in flow capacity while retaining all factory plumbing, making it the most reliable path to Stage 3 power levels for the MQB platform.

Comparison: GT2260S vs. Stock IS38
When upgrading from the factory IS38 turbo (found on the Golf R and Audi S3), the PowerMax™ 1 offers significant advantages in both headroom and durability.
| Feature | Pros (Advantages) | Cons (Trade-offs) |
|---|---|---|
| Performance | Supports up to 485 BHP; +17% flow vs IS38. | Requires ECU recalibration to utilize gains. |
| Reliability | Mar-M alloy turbine wheel rated for 1050°C. | Initial hardware cost is higher than a rebuild. |
| Design | Fully machined compressor port; robust thrust bearing. | Slightly later spool (approx 200-300 RPM). |
Why We Love It at MGM Leeds
At MGM Leeds, we don't just sell these turbos—we live with them. Our own Shop Golf R Mk7 is currently running the PowerMax™ 1, serving as our primary test bed for MQB performance. We chose this unit because it bridges the gap between a standard Stage 2 setup and a full-blown big turbo build, offering "OEM+" driveability with supercar-killing mid-range punch. Its reliability on track and street makes it our #1 recommendation for EA888 owners.
Professional Installation at MGM Leeds
A turbo upgrade of this calibre requires precision. Our workshop is fully equipped to handle the installation, including all necessary hardware swaps and cooling system bleeding.
