The TTE450L hybrid performance upgrade turbocharger based on the Original IHI turbocharger for the 2.0tfsi longitudinal engine. To construct a TTE450L 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 turbine and CNC mill the turbine housing to install a larger 9 blade turbine for greater gas flow.  

The 9 Blade TTE turbine is a special turbine designed by TheTurboEngineers.  Advantages are greater gas flow, reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost levels. This turbine is extremely light in mass so giving a reduced moment of inertia, meaning fast spool up for the size.  We replace the original thrust bearing for TTE upgrade 360 deg that is made in-house for long term durability.  


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.

Equilibrium

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 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.

 

Please note if sending a used turbocharger for the upgrade process.  TTE does not recondition the Electronic actuator or Diverter you send.  Your sent items will be re-installed.  A new diverter valve should always be fitted.

Upgrade your Existing Turbo

To upgrade your existing turbo, you will need to send us your non-damaged turbo. The listing price is the cost of upgrading a non-damaged turbo only. If your turbo is damaged, there may be extra cost on top of the listing price, we will provide you with a quote after inspection. All turbo will be closely inspected before the upgrade is carried out. You will also receive a report from our engineer after the upgrade is completed.


  • Audi A4 B8 / 8.5 - 07-15      2.0 TFSI - 180 / 211
  • Audi A5 B8 / 8.5 - 07-15      2.0 TFSI - 180 / 211
  • Audi A5 B8 / 8.5 - 07-15      2.0 TFSI - 225 / 230

 

Note: These turbochargers use K04 RS4 B5 compressor housings with 58mm inlets. Specific turbo intake pipes to suit are required . The turbine housings are RS6 C5 specific, so flange on downpipe is needed to match. They do not work with RS4 B5 specific downpipes but these can be adapted with use of a RS6 flange.


To ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch. We can do this either using your registration number(UK) or the last 7 digits of your VIN. Simply enter your car details prior to checkout.
