Garrett PowerMax Turbocharger 2.0 TSI MK7: Specs, Fitment, Worth It?

The Garrett turbocharger PowerMax Stage 2 kit for the 2014-2018 VW and Audi 2.0L TSI MK7 platform is a direct-fit turbocharger upgrade designed to bolt onto the factory location without custom fabrication. Garrett's PowerMax line produces platform-specific kits that match the factory turbo location, oil and coolant connections, and charge pipe routing for each supported application. The PowerMax Stage 2 designation for the MK7 TSI indicates a meaningful compressor upgrade over the factory IS20 or IS38 turbocharger included in the factory installation, delivering additional airflow capacity that directly raises the power ceiling on a tuned MK7 platform. This review covers the Garrett PowerMax Stage 2 specs, fitment, what builds it is right for, and whether this Garrett turbocharger upgrade is worth it for the 2.0L TSI MK7.

Garrett PowerMax Stage 2 -- What It Is and How It Fits

The Garrett PowerMax Stage 2 Turbocharger Kit (898200-5001W) is a complete upgrade kit for the 2014-2018 VW/Audi 2.0L TSI MK7 platform -- including the Golf GTI, Golf R, Audi S3, and other MK7-family vehicles running the EA888 Gen 3 2.0L TSI engine. The kit includes the turbocharger assembly along with the hardware required for a direct-fit installation at the factory turbo location. Key details:

• Application: 2014-2018 VW and Audi 2.0L TSI MK7 platform (Golf GTI, Golf R, Audi S3 and compatible MK7-family vehicles)
• Designation: Stage 2 -- a meaningful compressor upgrade over the factory IS20 or IS38 unit depending on the specific vehicle configuration
• Format: Complete upgrade kit -- turbocharger assembly plus installation hardware for a direct-fit installation
• Installation: Bolts to the factory location -- no custom manifold, no relocated charge pipes, no fabricated oil or coolant connections required
• Garrett series: PowerMax -- Garrett's platform-specific direct-fit performance upgrade line, distinct from the G-Series super core assemblies that require custom housing selection

The MK7 2.0L TSI platform uses the EA888 Gen 3 engine architecture. Factory turbos for this generation vary by specific vehicle: the Golf GTI uses the IS20 at the factory, while the Golf R and Audi S3 use the IS38. Both are Borg Warner units produced by the same manufacturer as the factory equipment. The Garrett PowerMax Stage 2 is a competing aftermarket unit designed to outperform both factory units in the power range a tuned MK7 platform operates in, with a compressor map sized for the stage 2 tune level rather than the factory calibration.

Top Picks: Garrett PowerMax and the MK7 TSI Upgrade Lineup

The Garrett PowerMax Turbocharger 2014-2018 VW/Audi 2.0L TSI MK7 Stage 2 Upgrade Kit (898200-5001W) is the direct-fit Garrett upgrade for the MK7 TSI platform. The kit addresses the factory turbo's compressor ceiling on a stage 2 tuned MK7 -- a tune, intercooler, and intake on a factory IS20 or IS38 will reach the compressor's efficient ceiling before the supporting modifications do, and the PowerMax Stage 2 raises that ceiling to match the stage 2 build level.

For the full MK7 upgrade approach, the PowerMax Stage 2 pairs with a stage 2 tune specifically calibrated for the new turbo compressor map, an upgraded intercooler capable of managing the additional heat load from higher boost, and a high-flow intake to match the improved turbo airflow capacity.

Match to the Build

The Garrett PowerMax Stage 2 is the right Garrett turbocharger for the following MK7 TSI build configurations:

• MK7 Golf GTI or R with stage 2 intake and intercooler, running IS20 or IS38: This is the primary use case. The stage 2 supporting modifications -- downpipe, intake, intercooler -- have raised the build to the point where the factory turbo is limiting the tune. The PowerMax Stage 2 raises the compressor ceiling to match the supporting modification level and allows the tune to access the additional power the intercooler and intake have enabled.
• MK7 Audi S3 with stage 2 modifications: Same application as the Golf R -- the S3 uses the IS38 factory turbo and the same stage 2 upgrade path. The PowerMax Stage 2 is the correct step when the IS38 has reached its ceiling with the stage 2 supporting modifications in place.
• MK7 TSI builds targeting above stage 2 output: The PowerMax Stage 2 covers stage 2 power levels. For builds targeting significantly above that range with high-flow fuel systems and stage 3 modifications, a larger platform-specific or custom turbo may be required depending on the specific power target and supporting fuel system capacity.

Signs the Factory MK7 Turbo Has Reached Its Limit

• Boost pressure ceiling hit on the dyno before the tune reaches its fueling target -- the compressor is at maximum flow before the fueling system is
• Compressor outlet temperature elevated at moderate boost levels -- the factory wheel is running outside its efficiency island, generating heat rather than efficiently compressing air
• Power plateau consistent with the known IS20 or IS38 rated ceiling on a build where the supporting modifications have been confirmed at stage 2 spec
• Intercooler outlet temperature elevated under sustained boost even with an upgraded intercooler -- hot compressed air from an inefficient factory wheel overwhelming the intercooler's cooling work

Frequently Asked Questions

Does the Garrett PowerMax Stage 2 fit the 2019 and newer MK7.5 GTI and Golf R?

The Garrett PowerMax Stage 2 kit (898200-5001W) is specified for 2014-2018 VW/Audi 2.0L TSI MK7. The MK7.5 generation (2017.5-2019 in some markets, varying by model year and region) may have a different turbo inlet or calibration that affects fitment. Confirm the exact vehicle model year and platform generation against the Garrett fitment list before ordering.

What tune is required for the Garrett PowerMax Stage 2?

A stage 2 tune specifically calibrated for the Garrett PowerMax Stage 2 compressor map is required to realize the full power gain. Running the PowerMax on a tune calibrated for the factory IS20 or IS38 leaves performance on the table because the fuel and boost targets are set for the factory turbo's map, not the PowerMax's. Use a tuner who supports the PowerMax Stage 2 for the MK7 platform to get a properly mapped calibration.

Is this kit a bolt-in or does it require fabrication?

The PowerMax Stage 2 kit (898200-5001W) is a direct-fit kit for the MK7 TSI factory turbo location. It bolts to the factory manifold, charge pipe, and oil and coolant connections without custom fabrication. A downpipe compatible with the Garrett turbo outlet is typically required if the factory downpipe does not match the outlet geometry -- confirm the downpipe fitment with the turbo before ordering both components.

Bottom Line

The Garrett PowerMax Stage 2 turbocharger kit (898200-5001W) is worth it for a 2014-2018 MK7 TSI build at stage 2 where the factory IS20 or IS38 turbo has become the compressor ceiling. The direct-fit format avoids custom fabrication, the PowerMax compressor map covers the stage 2 build level cleanly, and the Garrett brand brings engineering resources to the MK7 platform that factory-replacement alternative turbos do not match. Pair it with a PowerMax-specific tune and the stage 2 intercooler and intake already in place, and this Garrett turbocharger upgrade delivers the power the rest of the build has been waiting for.
