Presentation of the LOBA LO390-VAX turbo kit from LOBA MOTORSPORT
Possible power 400hp
Only compatible for Opel Astra 2.0 Turbo
A new production line for the BorgWarner 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 casing is also reworked to reduce the exhaust gas back pressure and thus be able to increase the exhaust gas discharge capacities.
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. The blades of the mfs wheel are studied in order to improve the output and the flow rate compare to other wheel of the same size.
The axis as well as the turbine and compressor side wheels are precisely balanced with lower tolerances than the original on the order of 0.5gr. The wastegate is also modified and Loba inserts a reinforced bearing from their homemade manufacture to improve its lifespan.
Thus and in general with all these modifications, Loba reduced the lag and improved the reactivity compared to the original turbo, and also improved the air flow capacities of the turbo at high revs. This turbo is a good compromise between power, responsiveness and reliability.
