The heart of the CTS Turbo MK5 2.0TFSI turbo upgrade kit is the Borg Warner K04-0064 turbocharger.? This turbocharger is commonly used in OEM applications such as the Audi S3 available in Europe. The highlights of this Borg Warner turbocharger in our kit is the forged mill; compressor wheel, which brings numerous benefits to the enthusiast. The technology used in the production of these turbos provides us with a variety of benefits, reduced compressor wheel weight (faster spool), increased strength, and greater surface area of the compressor wheel. Because of the 'forged mill' technology Borg Warner can increase the effective surface area of the compressor wheel, which results in greater airflow than conventional cast compressor wheels.
In addition to the Borg Warner K04-0064 the CTS Turbo MK5 2.0TFSI turbo upgrade kit uses a set of custom silicone hoses to relocate the factory diverter valve. Our diverter valve relocation uses the same principles as the OEM Audi S3, Audi TTS and Golf R. In addition to the diverter valve relocation our kit includes a new diverter valve housing to relocate the diverter valve, associated OEM gaskets, nuts, studs, and hardware. This kit is by far the best 'bang for the buck' modification available for VW and Audi enthusiasts with the 2.0TFSI engine.
