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 is also recommended.
For the racing enthusiast or those just looking for the best, this is the ultimate upgrade to fully maximize the power output of your N20 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 aren't standard rebuilds but rather brand new units with a new stock turbine custom cast and manufactured with an upgraded thrust system to ensure reliable and prolonged life.
Special Note: Installation times vary depending on application:
F22 228i xDrive, F30 328i xDrive, F32 428i xDrive - 7.0 hrs
F31/F34 328i xDrive, F36 428i xDrive - 7.4 hrs
F23 228i xDrive - 8.1 hrs
