The TTE600 upgrade turbos are regarded by many as offering the best balance between power, responsiveness and ease of fit for the Audi 2.7 Bi-turbo V6. This is the first TTE upgrade stage to utilise RS6 turbine housings for significantly greater airflow and power, with only a minimal compromise in responsiveness.
With the right hardware and software, 600+ hp is achievable, whilst the car retains its everyday practicality. This makes the TTE600 one of the most popular and proven upgrades within the 2.7T platform.

Frequently Asked Questions
Are these Plug & Play turbos?
Partly. Oil and water lines fit as on the original RS4 K04. Modification of downpipes is required due to the use of RS6 turbine housings.
What additional parts are required?
RS4 B5-specific Turbo Inlet pipes are mandatory. Downpipes must be modified with an RS6 flange.
Are any additional upgrades recommended?
Yes. It is strongly recommended to fit an RS4/S4 B5 upgrade oil pump at this power level.
