The TTE670 VTG is the first performance upgrade for the Porsche 997.1 turbo, developed to deliver extra power without compromising the character and quick response of the original turbos. This upgrade retains the original smaller VTG exhaust turbine housings and modified turbine wheels for early Spool-up, combined with a larger TTE billet compressor for significantly greater air mass and power. The result is a perfect balance between everyday driving comfort and a substantial performance boost.
