In order to attain maximum advertised 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 is also recommended.
For the racing enthusiast or looking for the premium, 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 which enables 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.
Benefits of the Dinan Big Turbo for the N20 Engine:
  • No core charge or core return is required.
  • Brand new upgraded turbo that is custom cast and manufactured with an upgraded thrust system.
  • Peak power: 345 HP @ 5500 RPM and 336 ft-lbs @ 4000 RPM and a max gain of 84 HP @ 6500 RPM and 77 ft-lbs @ 5500 RPM when coupled with other Dinan Performance upgrades.
  • Dinan Installation instructions detail a procedure which is quicker than BMW's turbo replacement procedure saving the end-user money and time at the shop (Applicable to RWD vehicles only).
  • Includes o-rings and gaskets needed for complete installation on a RWD vehicle only. If installing on an xDrive vehicle Dinan P/N D313-0117 is required for additional installation hardware.
  • Factory matching new car warranty (4yr/50k) when run in Dinan specification.
  • 50 State Emissions legal; CARB EO # D-176-49.
  • Larger billet compressor/impeller wheel that allows ~30% greater flow over stock which then enables additional boost to be realized while retaining efficiency.
  • Brand new stock turbine.
  • Turbo assembly is compatible with both mechanical/vacuum and electric wastegate vehicles.

Hardware supplied in the base turbo kit is only complete when installing on a RWD vehicle. If vehicle is an xDrive vehicle then additional hardware is required to complete installation. We offer Dinan P/N D313-0127 for those cases.
