TTE390 hybrid turbocharger for transversely installed 1.8T engines such as Audi A3, S3, TT, Seat Leon, Octavia, etc.
For the production of the TTE390 upgrade turbocharger, TTE initially uses a standard K04-64 from the Golf 5 ED30, its manifold and compressor housing machined by CNC milling machine so that the loader can be screwed to the head of the 1.8T without an adapter plate. A special, milled 2871X TTE compressor wheel replaces the standard cast part. Not only is it larger than the standard part, it is also equipped with the extended tip technology. It therefore promotes significantly more air mass and still responds very early. The standard compressor housing is machined with a CNC milling machine so that it can accommodate the new wheel.
The turbine wheel experiences the tried and tested abrasion by TTE, the so-called clipping. The ends of the turbine blades are rounded to a certain contour, which increases the throughput, reduces the load on the turbine and thus reduces the exhaust gas back pressure.
The 360 ° bearing used ensures a higher load capacity. The standard pressure cell of the wastegate is adapted to the new environmental conditions by equipping it with a stronger spring. Thanks to the TTE brackets, the spring rate can even be further adjusted by the owner, if this is desired or necessary.
The extremely precise balance of every TTE turbocharger is a key element for longevity, sound and function, which is why TTE attaches great importance to this process. Each individual component is initially balanced at up to 2800 rpm in several levels. The trunk group is then assembled and dynamically balanced again in several levels at up to 250,000 rpm. At TTE, this process takes place on a VSR (Vibration Sorting Rig) balancing machine; each turbocharger is supplied with a balancing protocol that you can clearly assign to your TTE charger using the serial number, and which you can trace at any time with which values your turbocharger left the factory.

The price for the conversion of your series charger is only valid if an operational, undamaged original charger is sent. If the part sent is not suitable for conversion, you will receive a cost estimate after it has been dismantled.
The name of the turbocharger also indicates the maximum performance! As an example, a TTE350 creates approx. 350 hp and a TTE350 + a little more. Often, however, further modifications to the environment, i.e. engine, intake, AGA, etc. are necessary in order to achieve this performance target. Please contact us if you have any questions, we will be happy to help.
The conversion is only possible if an executable, original K04-64 charger is sent in!
The basis for this TTE turbocharger differs significantly from the series, so this is not a plug & play solution! Additional, extensive work and / or parts may be necessary for installation in your vehicle.
