Additional Information

The Dinan Big Turbo (D310-0110A) is the ultimate performance upgrade for the racing enthusiast, engineered to fully maximize the power output of the EWG (Electronic Wastegate) $\text{N}55$ engine found in various $2012-2019$ $\text{BMW}$ ' $\text{F}$ ' Chassis models. This is a fully cast turbocharger, manufactured to Dinan specifications, featuring a larger billet compressor/impeller wheel that allows approximately $30\%$ greater flow over stock. This increased flow enables additional boost pressures at higher engine speeds while retaining efficiency. To ensure long-term reliability, the unit is reinforced with an upgraded thrust system over the stock turbo.
