The heart of the CTS Turbo B7 A4 2.0T 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 highlight 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 air flow than conventional cast compressor wheels.In addition to the Borg Warner K04-0064 the CTS Turbo B7 A4 2.0T turbo upgrade kit uses associated OEM gaskets, nuts, studs and hardware and test pipe to connect to your factory downpipe.  This kit is by far the best 'bang for the buck' modification available for B7 enthustiasts with the 2.0T engine.Power with Unitronic Stage 2+ tune: 335hp/335lb-ft tqUNITRONIC STAGE 2+ : 335HP / 335LB-TQKit must be used with test-pipe that is included.Additional parts required:Autotech HPFP upgradeAudi S3 fuel injectorsK04-specific software from any tuning company
