Introducing here what many will love. Designed to give a great blend of power, response, and ease of fitment and our first step utilizing THE 08 turbine housings (k08) for greater flow and power. TTE680 Performance turbochargers can offer big HP with the right hardware and software. These really will offer a great balance of high power and response.

Engineered & Enhanced

TTE680 uses RS4 compressor covers that we CNC machine in house to an optimum clearance to allow fitment and maintain the efficiency of a larger more advanced billet TTE2280X Extended tip compressor wheels, inducer 45.1mm exducer 59.4mm. We also as standard CNC mill the air inlet port on the compressor housing to remove a lip right before the compressor wheel to smooth the transition to the intake pipes to maximise performance.

The 2280X compressor wheel design features promote greater airflow using a low inertia wheel that performs like a wheel of even greater size and mass. Extended tip technology enables the user to have faster spool-up at lower engine speeds while providing high boost with less heat for the powerful top-end performance.

Turbine and shaft are origanal RS6 K04 size items with a special curved clip. A TTE grinding process to the turbine blade tips, to reduce area, thus increasing gas flow and so reduce back pressure and lowering exhaust gas temperatures, allowing safer higher boost level's.

Turbine and shaft are TTE 9BLADE items with a special blade design thus increasing gas flow and so reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost levels vs RS6 Clipped we did use. 

THE 0.8 Exhaust turbine housing (K08)with there larger volute allows much more gas flow and is CNC machined to match the TTE 9blade turbine

Special profile 360 deg high-performance motorsport journal bearing are fitted, to remain durable at higher loads with no loss in transient response.

Actuators used are uprated sprung OE units fitted with our reinforced clamps for trouble-free operation.

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 serial numbered balance test result document.

Reconditioned Upgrade Turbo - Send To TTE is based on you sending good condition K04 RS4 OE Turbochargers

ATTENTION:

These turbochargers use K04 RS4 B5 compressor housings RS4 B5 specific turbo intake pipes are required. The turbine housings are RS6 Fitting 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. 

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 B5 S4 2.7T
• Audi C5 A6 2.7T
• Audi B5 RS4 2.7T

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.

Warranty

One year TTE warranty.

Delivery

To upgrade your existing turbo, the estimated delivery time is around 3-4 weeks after receiving your existing turbo. 

Our new turbos are made to order, the estimated delivery time is also 3-4 weeks after receiving your order. 

TheTurboEngineers(TTE)

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.
