HPA 2.0T K04 Hybrid Turbo Upgrade - Transverse
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 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 turbo assembly is one of the most advanced units available in North America, featuring many benefits over the competition, including:
- All-inclusive hardware kit
- Cast design for efficient heat transfer
- Lightweight aluminum compressor for quicker spooling
NEW FOR 2016
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 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 the proprietary CHRAs.
HPA’s K04 uses a newly cast compressor housing to incorporate the factory placement of the diverter valve. By casting the housings, the costly CNC adapter and housing modifications are no longer required and the 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.
Each CHRA is built to the OEM quality specifications, with the individual components of the rotating group balanced on a Schenk Balancer. Once fully assembled, each complete CHRA assembly is balanced with a VSR Balancer. The VSR Balancer is used and approved by leading turbo manufacturers Borg Warner, Garrett Honeywell, and IHI, ensuring a perfect assembly.
To guarantee that the castings, CHRAs and subcomponents would meet the demands of our customers, weeks of dyno testing and months of track sessions were realized across 2015.
