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:
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.

LONGITUDINAL VERSUS TRANSVERSE DESIGN
The two different layouts simply define the manner in which the engine is mounted in the chassis of your vehicle. A transverse design simply means the crankshaft of the engine is aligned perpendicular to the length of your vehicle as seen in most FWD cars. This transverse drivetrain layout is seen in most modern 2.0L Volkswagen cars on the road today. Longitudinal means the opposite where the crankshaft of your vehicle is parallel with the length of the car, allowing for efficient implementation of RWD and AWD drivetrains. An example of this layout can be seen in most Quattro equipped vehicles.
