To unleash the true potential of your 2.0T, the K04 turbo that is equipped on the Golf R / S3 is a much more robust choice than the factory equipped IHI (KO3) turbo, which runs out of breath mid-way in the RPM range. The HPA K04 Hybrid upgrade offers a higher operational boost range, while still working with the stock componentry; making for a natural and cost-effective upgrade. This K04 Hybrid conversion allows for a seamless integration, without the need for custom fabrications or aftermarket diverter valves.
HPA has now developed our own high performance K04 Hybrid Turbo conversion that allows the factory K03 diverter valve to be installed in the OEM location, without a CNC port adapter. Our K04 Hybrid turbo assembly is one of the most advanced units available in North America, featuring many benefits over the competition.
With a market flooded with poor quality aftermarket clones and modified OEM assemblies, HPA has taken a fresh approach to supplying its customers with a K04 Hybrid Turbo for the Gen 1 and 2 EA 888 and EA 113 engines at an affordable price.
Reworked OEM parts result in high costs with no appreciative performance gains. For over two decades, HPA has been building hybrid turbines for the VR6 powertrain, working with the very best suppliers both overseas and domestically. HPA ensures the tightest quality standards are maintained in castings and the assembly of our proprietary CHRA's which feature a larger rotor and steeper turbine fins for increased tq delivery and rpm range.
HPA’s K04 Hybrid uses a newly cast compressor housing to incorporate the factory placement of the diverter valve. By casting the housings, costly CNC adapters and housing modifications are no longer required and associated costs and manufacturing time are removed from the kit assembly. To ensure a good result at first fire up, each HPA K04 Hybrid includes a new diverter valve representing the latest design updates from the factory.

- Simplified Design for Ease of Install
- Diverter Valve in OEM Position
- Block-off plate for PCV system (TSI)
- Knife-edged, billet compressor wheel
- Quicker Compressor Spool
- Higher Output Across the Full RPM Range
As the factory IHI/KO3 runs out of breath at 5500rpm, the performance advantage of the K04 can be maximized by adding HPA’s Cast 2.0 Short Runner Intake Manifold. As the K04 pumps more air from 5500 RPM to redline, the HPA intake will support this demand by flowing 12-24% more air into each individual intake valves set. With the 2.0 Intake Manifold’s 42% larger intake plenum, initial throttle demand will be met with greater volume, allowing your software calibrator to develop more low end TQ. Take advantage of HPA’s race developed calibrations to fully maximize the RPM band of your 2.0T.
