TTE535 hybrid performance upgrade turbocharger based on the Original IS38 turbocharger for the 3rd generation VAG 2.0TSI following on from the TTE525R upgrade stage. Stage 3+ power, with great spool and response. We feel this is the best balanced performing hybrid IS38 available on offer.

Please note that if you choose to upgrade your existing turbocharger, it will have to be shipped out of the country. The typical turn around time for this turbocharger is around 30 days depending on what shipping options you use. Please click or tap here for more information on this process.

Engineered & Enhanced EA888 Gen 3 - IS38

To construct a TTE535 TTE first 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. TTE then replaces the original IS38 turbine and CNC mill the turbine housing to install a larger lightweight 9 blade turbine for greater gas flow. TTE also replaces the original thrust bearing for TTE upgrade 360 deg that is made in-house.

TTE also fits their 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.

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.


Precisely balancing 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 their balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using the TTE 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 their 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.
