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 and intake is also recommended.
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 MWG N55 Engine:
- Peak power: 428 HP @ 5500 RPM and 443 ft-lbs @ 4500 RPM and a max gain of 122 HP @ 6000 RPM and 107 ft-lbs @ 6000 RPM when coupled with other Dinan Performance upgrades (Data from F30 335i MWG w/ MPPK and automatic transmission. Other variants may produce different results).
- 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.
- No core charge or core return is required.
- Brand new upgraded turbo that is custom cast and manufactured with an upgraded thrust system.
- 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 mechanical/vacuum wastegate vehicles only.
Kit only compatible with mechanial / pneumatic wastegate vehicles. There is a seperate kit (D310-0110) for cars equipped with an electronic wastegate.
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 D313-0117 for those cases.
Installation times vary depending on application:
F30 335i RWD - 5.0 hrs
F30 335i xDrive - 9.9 hrs
