TTE Audi Seat VW 2.0 1.8 TSI EA888.3 MQB IS38 TTE555 Upgrade Turbocharger (Inc. TT, S3, Leon & Golf R)

The Turbo Engineers(TTE)

  • £3,293.81
    exc. VAT £2,744.84


TTE555 is our latest hybrid performance upgrade turbocharger for the new 3rd generation VAG 2.0TSI following on from our proven TTE470 upgrade stage. Stage 3 power, same near stock turbocharger spool and response.

Engineered & Enhanced EA888 Gen 3 - IS38

To construct a TTE555 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 optimum gap to match the new compressor profile. We replace the original IS38 turbine and shaft and CNC mill the turbine housing and install a larger clipped and lightened turbine for greater gas flow. We CNC modify original compressor cover, for increased airflow. We replace the original recirculation solenoid valve with a Motorsport atmospheric blow-off valve that's included in the price.

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 cancelling device, and so improving the flow, giving less surge and enhancing the sound.

The clipping of the turbine is a special TTE grinding process to the turbine blade tips. Curved to alleviate stress from a process. Clipping reduces blade area thus increasing gas flow and so reducing backpressure and lowering exhaust gas temperatures, allowing safer higher boost level. This process also gives a secondary advantage of removing some material, lightening an already lightened turbine thus reducing the rotational mass improving moment of inertia, meaning fast spool up.



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 serial numbered balance test result document.

Reconditioning price shown is based on overhauling and reconditioning, upgrading an undamaged used as new turbocharger within specification. Only once cleaned and dismantled, inspected then a firm price be made.



TheTurboEngineers GmbH based in German is a dynamic and highly innovative turbocharger engineering company, specialised in production of motorsport turbochargers to the highest quality and greatest efficiency with attention to detail. Every component is optimised on long term reliability.

TTE are focused on the construction of prototypes from a concept, through to completion with all work mostly being done in-house to TTE's extremely high standards in Germany. TTE is a fine example of German engineering at its best. 

Small details are important to TTE, as is the conversion of existing OE turbochargers to new upgrade specifications, be it new or from a supplied used turbocharger.
TheTurboEngineers GmbH consults and provides to race teams and many well known tuning houses, looking for the best engineered performance turbochargers available.




Compatibility Check

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.
