In order to gain maximum power gains, these big turbos will need to be paired with DINANTRONICS Stage 4. Dinan’s intercooler to fully regulate the boost increase and deliver a polished product, the exhaust and intake are also recommended.
For the racing enthusiast or looking for the premium, this is the ultimate upgrade to fully maximize the power output of your EWG N55 engine. The compressor wheel inside the turbocharger is increased in size allowing ~30% greater flow which enables additional boost pressures at higher engine speeds while retaining efficiency. These are fully cast turbos that are manufactured to Dinan specifications along with an upgraded thrust system over the stock turbo to ensure reliable and prolonged life.
Benefits of the Dinan Big Turbo for the EWG N55 Engine:
Kit only compatible with vehicles using an electronic wastegate. There is a separate kit (D310-0115) for cars equipped with a mechanical / pneumatic wastegate (applies only to the 335i).
