TTE600 Upgrade Turbochargers RS4 / S4 b5 / A6 2.7t

Introducing here what many feel the best blend of power, response and ease of fitment and our first step utilizing RS6 turbine housings for greater flow and power. TTE600 Performance turbochargers can and do make over 600PS with the right hardware and software, yet offer only a little loss in response but offer big step too more power. These really do offer a great balance of high power and fast response.

Key Points:

Genuine BorgWarner RS4 Compressor housings and key components
Genuine BorgWarner RS6 Exhaust housings
TTE Billet 2280X Compressor geometry (new)
CNC Ported compressor inlets
Genuine TTE 9BLADE Turbines
Genuine BorgWarner Reinforced Motorsport bearing system
Genuine BorgWarner Modified reinforced and synchronized actuators
Single parts finely balanced then components assembled and high-speed VSR balanced
Supplied with a serial numbered balance test documents for each turbocharger
Installation as original RS4 K04 (with regard to oil and water line, all else see bellow)
600PS Capable
Designed, Machined & Built by TTE in Germany

More info & pricing :


These turbochargers use K04 RS4 B5 compressor housings RS4 B5 specific turbo intake pipes 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.
