TTE280 performance turbocharger for the 1.8T VAG transverse platform. Offering 280+PS with near Plug & Play fitment. To produce this K04 TTE280 upgrade turbocharger TTE uses a much larger BorgWarner 2283 billet compressor wheel, chosen because it is highly efficient and features BorgWarner Extended tip technology, creating extremely high flow for comparative size, but giving a compressor map that's very wide.


Precisely balanced 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 our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes, 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 TTE's in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.
