This Dinan "fit-kit" is required for fitting the Dinan Turbo Inlet (T#8076778) to the Dinan "G-chassis" Intake (T#21604305).

This kit includes an o-Ring, spring clip and a custom silicon hose for a painless install.

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 fully cast turbos that are manufactured to Dinan specifications along with an upgraded thrust system over the stock turbo 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:

• Fully cast turbo that is manufactured to Dinan specifications with an upgraded thrust system thereby avoiding lengthy turnaround times caused by a core exchange program. 
•  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 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 (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.

Because of where the stock boost hose is located - often leaks go unnoticed. Replace your stock hose that is prone to failure with this 4ply Fluorosilicone hose that is better suited to handle the pressures, temperatures, and withstand total failure caused by oil. Couplers are CNC machined. Following instructions is necessary - if installed incorrectly, the hose will seem too short for its application.
