TTE855 EVO 2.5TFSI Upgraded Turbocharger

A TTE855 Is an original RS3 8V.2/TTRS 8S DAZA, DNWA turbocharger that we the THETURBOENGINEERS Rework to make a class-leading performance hybrid for the older generation CEPA, CEPB & CZGB motors.

The TTE855 Hybrid turbocharger was the evolution of our highly acclaimed TTE777. Using some key features like a bigger billet compressor and CNC porting and other gas flow improvements. 

The compressor wheel is exchanged for a milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, we change the original exhaust turbine for a far larger but very lightweight 9 blade TTE designed turbine, for lower exhaust gas backpressure, giving greater performance. We also fitted a proven TTE motorsport upgrade bearing system for durability.

Boost response as always is focused on when we were designing this unit and it does not disappoint with test results showing 500Nm at only 2620 RPM and 900Nm at 3500RPM !.     

With the TTE855 stage we have CNC ported the exhaust manifold to match the OEM gasket at the head flange and smooth the transition in each exhaust runner to improve gas speed and flow, so improving efficiency to the much bigger 9 blade low mass turbine and so driving the larger compressor harder. We also made other power modifications with regards to the turbine side of the TTE855 unit to increase gas flow.  

If ordering new, we use the latest generation of BorgWarner original turbochargers with the latest spec Audi thermal heat isolation shielding on the exhaust manifold & turbine housing to lower engine bay temperatures and ensure the best performance and safety.  

Please note if you send an older generation turbo, without the original AUDI thermal shielding for the "upgrade" process, we will rework your turbo and return without the shielding, unless you buy the extra thermal Isolation process.  Depending on stock availability we may substitute TTE thermal shielding and give AUDI original thermal shielding instead. 

We cannot upgrade the ORIGINAL K16 CEPA, CEPB OR CZGB Turbo to this stage, Biggest possible for the K16 is the TTE500+ Upgrade Turbocharger

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 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.

Notes: For the core rebuild option & New Core, the shipping covers return shipping back to you upon completion of the build. You are responsible for all shipping fees associated with getting the turbo to its destination. Instructions will be sent via email by XLR8 to you within 2-3 business days with instructions on how to pack and ship your turbo to TTE.

Turbochargers need to be in good working order, complete and free from damage to comply with the price shown. Any turbochargers sent with damage or missing parts may incur extra charges. You will be emailed details to discuss if damage is found outside of the standard TTE upgrade process.

Please do not send any accessories, oil lines, valves, hoses, parts, or components apart from the turbocharger and actuator as we will not be responsible for any losses or breakages of parts.  

Pack any turbocharger individually and extremely well to avoid any transit damage, double boxing is recommended. We also recommend adding double shipping labels to the outside of your package and place one inside to ensure your package does not become lost. 

We recommend using only DHL, DPD, UPS, TNT, FEDEX carriers. Please send using Express Service ONLY. Using other carriers or non-express will likely cause parcel delays at customs if sending from outside the EU and possible extra fees or return to you. 

Once you have sent your turbocharger/s to TheTurboEngineers they will be fully checked and validated within a 2 week timeframe for an upgrade and they will continue to process. If for any reason TTE can not upgrade your turbocharger/s or extra costs required. e.g. find damage, missing parts. We will contact you.  

If turbochargers arrive at TheTurboEngineers without a Packing Slip they will not be processed quickly and will be delayed until we can determine the owner & order related!
