Welcome to the TTE1200VTG Upgrade turbocharger stage for the 911 GT2 RS 3.8l 700PS flat-6. To construct a pair of TTE1200 VTG change the original compressor and employ a far larger and more efficient billet wheel and mill the compressor cover to the optimum gap to match the new compressor profile.
Precisely balancing turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving strict balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using a single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using a VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial numbered balance test result document.
TTE1200 VTG can be fitted to Any 3.8 with VTG control but you would need GT2 RS Exhaust Manifolds as turbo flange different, also oil, water lines, charge pipes and intakes.
