Product information "TTE350+ IS12 Upgrade Turbocharger"






TTE350+ is our very latest IS12 hybrid performance upgrade turbocharger based on the Original IHI IS12 turbocharger for the 3rd generation VAG 2.0TSI.   TTE350+  Offers stage 3 hybrid power, with the IS12 amazing spool and response. We feel this is the best performing sub 400hp hybrid available on offer today.

Engineered & Enhanced  EA888 Gen 3 - IS12

To construct a TTE350+ we change the original compressor and employ a far larger and more efficient billet wheel with extended tip technology and mill the compressor cover to the optimum gap to match the new compressor profile. We replace the original IS12 turbine and CNC mill the turbine housing to install a larger 9 blade turbine.  We also replace the original thrust bearing for the TTE upgrade 360 deg that is made in-house. 


The larger 9 Blade TTE turbine advantages are greater gas flow, reducing backpressure, and lowering exhaust gas temperatures, allowing safer higher boost levels.


We also fit our TTE CNC silencer delete. Modifying the turbo discharge silencer, removing the original baffle internals and fitting a new straight-through section, removing any restriction and its function as a noise-canceling device, and so improving the flow and enhancing the sound.




Precisely balancing our 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 using our single parts machine, then components are assembled, and then the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using our in house 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.
