The TTE850+ VTG is a high-performance turbo upgrade for the Porsche 991.2 turbo S 3.8 flat-6, developed to deliver maximum performance whilst retaining the unique VTG response. This upgrade is based on original Gen 2 VTG turbochargers, which are fully upgraded internally with larger billet compressors, optimised turbine geometry and improved gas flow. The result is a potential output of 850+ pk with fast Spool-up, strong mid-range and OEM-quality driving characteristics.
