LOBA LO650 audi RS6 C5 4.2L V8 Biturbo turbos kit

Here is our Biturbo LOBA LO650 audi RS6 C5 4.2L Biturbo Kit

Possible power over 650hp

Now we are proud to present to you the ultimate improvement of the original Audi RS6 C5 4.2L Biturbo biturbo kit. The LO650 biturbo kit is the result of several years of development and evolution on the 4.2L Biturbo platform.

A new production line of the BorgWarner K04 turbo is used and is heavily modified. Optimized with a 5-axis digital machine, the compressor housing is significantly modified as well as the interior surface allowing an optimized improvement of the air flow.
The turbine housing is also reworked to reduce the back pressure of the exhaust gases and thus be able to increase the evacuation capacities of the exhaust gases.

A new compressor wheel forged and machined by Loba, is integrated. It has a unique design in terms of geometry and size and weighs only 39.8gr and is very resistant. the wheel is 25% lighter than the original one. The blades of the mfs impeller are designed to improve efficiency and flow compared to other impellers of the same size.

The axle as well as the impellers on the turbine and compressor side are precisely balanced with smaller tolerances than the original one of around 0.5gr. The wastegate is also modified and Loba inserts a reinforced bearing of their manufacture in house to improve the life of this one.

So and in general with all these modifications, Loba has reduced lag and improved responsiveness compared to the original K04 turbo, and also improved the airflow capabilities of the turbo at high revs. This turbo is a good compromise between power, responsiveness and reliability.
