Modifications

Our Stage 1 Turbos are completely blueprinted OEM BMW Turbos, which get modified to our specifications including a new, more efficient high flow turbine wheel. By increasing the efficiency of the turbine we’re able to get more fresh air into the combustion chamber of the engine while remaining the same boost level. Together with a proper tune this results in a huge gain in power!

Results

With our Stage 1 Turbos we have seen pretty impressive gains with no negative effect on the daily abilities of the car:

Although the turbo does have a bigger, heavier turbine wheel it still is capable of producing more torque over the complete RPM-Band than the factory turbos! Still, the BMW 335xi is a great car for daily driving with no drawbacks compared to stock, but if you floor it and use all its muscles be sure to scare some serious sport cars!
