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.
Benefits of the Dinan Big Turbo for the EWG N55 Engine:
- Factory turbo that is machined to Dinan specifications 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.
- Turbo assembly (D310-0110) is compatible with electric wastegate vehicles only.
- Peak power: 445 HP @ 6000 RPM and 455 ft-lbs @ 3000 RPM and a max gain of 128 HP @ 6000 RPM and 113 ft-lbs @ 6000 RPM when coupled with other Dinan Performance upgrades. (Data from F22 M235i.) 448 HP @ 6500 RPM and 417 ft-lbs @ 3000 RPM and a max gain of 152 HP @ 6500 RPM and 123 ft-lbs @ 6500 RPM when coupled with other Dinan Performance upgrades. (Data from F32 435i. Other variants may differ.)
- 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.
- Includes o-rings and gaskets needed for installation.
- Factory matching new car warranty (4yr/50k).
- CARB EO is pending.
Core Program: The N55 EWG turbo is part of the CORE program we utilize at Dinan so you will be charged an additional fee on top of MSRP initially. This fee will then be refunded to you once your old turbochargers have been received at Dinan and passed a quality check. This ensures we have a continuous stream of product for rebuilding purposes and the lowest possible price to the consumer. Any cores sent back that are damaged and/or unusable will not be given credit for. Please ensure adequate packaging and packing is being used to protect returning cores.
