Garrett Powermax G25-660 Stage 2 898200-5001W VW 2.0L TSI MK7 2014–2021 600KM

Replacement part numbers for turbochargers or the turbocharger models for which the part covered by this offer is designed:

The Garrett PowerMax Stage 2 is a brand-new turbocharger designed as a direct replacement for the stock unit in 2.0 TSI engines on the MQB platform. The kit is delivered fully assembled, with a factory-calibrated electronic control unit and a complete set of mounting hardware designed to fit the original mounting points. It requires no modifications to the intake manifold, exhaust system, or intercooler.

The design is based on the G25-660 turbocharger. Compared to the factory IS38 unit from the Golf R, it provides 59% greater airflow. G-series wheel aerodynamics have been applied—on both the compressor and turbine sides. The turbine wheel is made of Mar-M alloy, and the twin-scroll turbine housing is made of stainless steel; both components are designed to operate at temperatures up to 1050°C. The rotor runs on a ball bearing, which distinguishes Stage 2 from Stage 1, which is based on a slide bearing.

The compressor housing features a factory-machined speed sensor socket—ready for installation without additional machining.

Unlike hybrid units built on used housings, the PowerMax is manufactured entirely on Garrett’s production line, with the same quality control as turbochargers supplied to automakers.

The turbochargers were installed by the manufacturer in the following vehicles:

What It Takes to Achieve 600 KM

The stated power output represents the potential of the turbocharger itself, calculated based on the choke flow from the turbocharger map. The result on a specific vehicle depends on other modifications and calibration.

Garrett achieved the stated values on an Audi TT 2.0 TFSI (EA888 Gen 3) additionally equipped with: an enlarged intercooler, a dedicated exhaust system, reinforced pistons with a reduced compression ratio to 9.2:1, an upgraded fuel system (larger high-pressure pump and larger injectors), reinforced valve springs, and transmission software. Fuel: 102-octane gasoline blended with ethanol.

These values cannot be safely achieved with stock engine components.

Warnings

The maximum rotational speed is 165,000 rpm. Operation above this value is at the user’s own risk and will result in damage and premature failure. Garrett recommends installing the RPM sensor in the factory-prepared socket—part numbers 781328-0003 (sensor with a gauge) or 781328-0004 (sensor only), sold separately.

Modifying a vehicle with these products is done at the user’s sole responsibility and risk and may affect the manufacturer’s warranty, type approval, and the vehicle’s roadworthiness. It is the buyer’s responsibility to ensure compliance with regulations regarding emissions, noise, safety, and vehicle certification.
