Dinan Big Turbo BMW N20 -BMW 228i 2016-2014 228i xDrive 2016-2015 328i 2016-2012 EWG - Dinan D310-0120

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. 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.
