To unleash the true potential of your 2.0, 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 their 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, including:

• All-inclusive hardware kit
• Cast design for efficient heat transfer
• Lightweight aluminum compressor for quicker spooling

HPA’s K04 Hybrid 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 your demands, weeks of dyno testing and months of track sessions were realized across 2015.

Additional Details 

Fitment:

• Audi A4 B8 (2009+) -- Audi A4 (B8) requires a mandatory HPA downpipe for fitment.
• Audi A6 C6 (2005-2011)
• Audi Q5

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.
