Ensure proper sealing when installing the turbos on your N54.

Kit includes:

• 16 - ASA M7x39 studs
• 16 - Flange nuts
• All required gaskets and o-rings
• Water pump install hardware
• Replacement vacuum hose
• T-bolt clamps

Helpful hints:

For complete installation instructions, refer to Haynes Service Manual (T#193950).

Both downpipes must be removed to remove either front or rear turbo. Tie rod end may need to be separated from knuckle for clearance. Steering rack may also need to be rotated away from subframe for access. Valve cover heat shield will need to loosened and pushed upward to get clearance for turbo manifold removal.

If studs back out of cylinder head and nuts are seized to studs, replace studs. Thread studs in to head by hand to prevent cross threading. When installing the new studs in the cylinder head, use a high temperature loctite in the cylinder head side, and copper anti-seize on the nut side.

To make more room for access to the front turbo, remove the rubber line running in front of the subframe that attaches to the back of the map thermostat and remove the clip. Cut off the OEM clamp and replace it with a new hose clamp as well.

Complete removal of the water pump is not required. Detach the water pump from the side of the block and push it out of the way to make more room for access to the front turbo. If water pump is unbolted from the block, the aluminum bolts must be replaced.

Protect your Mini with the Turbo Heat Shield, an essential accessory to prevent hood paint discoloration, scoop warping, and underhood heat damage caused by excessive turbocharger heat. Additionally, it enhances the underhood appearance of your MINI. This metal plate mounts to factory points using supplied hardware, effectively reducing the amount of heat that bypasses the factory shield. While not encasing the turbocharger entirely, it serves as a secondary defense, complementing the factory-installed heat shield that isn't fully effective in preventing long-term hood paint and scoop damage.

• Prevents hood paint discoloration and scoop warping
• Guards against underhood heat damage caused by excessive turbocharger heat
• Enhances underhood appearance
• Mounts to factory points with supplied hardware
• Acts as a secondary defense in addition to the factory heat shield

Product Description:

M7 Speed proudly presents the Limited Edition Turbo Heat Shield for all Gen 2 Turbocharged 1.6-liter MINI Coopers. This exclusive release features the same top-selling heat shield, now in a custom Hacienda Wrinkle Red powder coat finish. Perfectly complementing the limited edition MAXX Flo intake system also available in this striking red finish.

Features and Benefits:

• Fits both the N14 and N18 MINI 1.6-liter turbocharged engines.
• Open design allows heat to escape down and away from the turbo, enhancing heat rejection through radiator airflow.
• Ceramic thermal insulation reduces heat transfer, preserving the engine bay, hood, hood scoop, and hood graphics.
• Simple DIY installation, mounting directly to the engine at easily accessible factory holes.
• All necessary mounting hardware included, with a 15-30 minute installation using basic hand tools.
• Adds a finished look to the engine compartment, enhancing the WOW! effect.

Turbo maintenance has become part of our daily lives here. Our Service department does several turbo overhauls, wastegate adjustments, carbon cleaning, and upgrades every week. For the DIY owner, however, having a complete overhaul kit takes some of the stress out of 335 turbo replacement and this kit includes all of the basic items. It's highly likely N54 turbos will have to be replaced before 100,000 miles. Signs of a failing turbo are high oil consumption and blue smoke from exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems the turbos need to be replaced. 

This package uses new (not rebuilt) Mitsubishi turbochargers (the original supplier to BMW). These are essentially direct replacement turbos but we went straight to the manufacturer instead of going through BMW. They are the same as the factory turbos but without a BMW logo so you save yourself a few hundred dollars. It includes everything that needs replacement during a 335 N54 twin turbo overhaul -

• Front and rear new OEM Mitsubishi turbos (the original supplier of BMW turbos)
• 1 gallon of Genuine BMW coolant
• ​16 - ASA M7x39 studs
• 16 - Flange nuts
• All required gaskets and o-rings
• Water pump install hardware
• Replacement vacuum hose
• T-bolt clamps

These are brand-new turbos so a core charge does not apply.

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.
