Dinan Product Description
For the racing enthusiast or those just looking for the best, 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 thus enabling additional boost pressures at higher engine speeds while retaining efficiency. These are rebuilt factory turbos that are machined to Dinan specifications along with an upgraded thrust system to ensure reliable and prolonged life. In order to attain maximum advertised power gains these big turbos will need to be paired with DINANTRONICS Stage 4, as well as Dinan’s intercooler to fully regulate the boost increase and deliver a polished product although the exhaust and intake are also recommended.
Note: Installation times vary depending on application: F22 M235i RWD, F30 335i RWD, F32/F36 435i RWD - 5.0 hrs. F22 M235i xDrive, F30 335i xDrive, F32 435i xDrive - 9.9 hrs. F34 335i xDrive, F36 435i xDrive - 10.4 hrs
