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.

MINI B38/B36 JMTC Refurbished Turbocharger offers a complete overhaul to restore turbocharger performance to a like-new condition. JMTC's refurbishment process includes a thorough cleaning and replacement of all internal components that may have been worn or damaged, such as turbine shaft bearings, thrust bearings, pressure seals, cartridges, and end housings. Components not meeting stringent standards are replaced, ensuring optimal performance.

• Thorough Overhaul: Includes cleaning and replacement of all internal components to ensure reliable functionality.
• High-Quality Parts: Only components meeting strict quality standards are used, with damaged parts replaced.
• Extended Warranty: Refurbished units retain JMTC's full warranty for added peace of mind.

Additional Recommendations:

• Pre-Installation Tips: For optimal results, JMTC recommends refurbishing the OEM catalytic converter or using a high-flow downpipe and installing a new oil line. This helps prevent recurrence of previous issues and ensures the turbo operates at its best.

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.

JM Turbo Cooper - Extreme GTD47 K04 Turbocharger Upgrade

JM Turbo Cooper offers the Extreme GTD47 K04 turbocharger upgrade designed to deliver outstanding reliability and high-performance gains for the 2007+ MINI Cooper. This upgrade is a top choice for Mini and Peugeot owners, providing exceptional power output for applications exceeding 280hp.

Update: The improved gasket design on the back side now features a seamless gasket inset, and the package includes a new gasket for your convenience.

The JMTC Extreme GTD47 upgrade boasts a high-pressure, high-flow, dual-scrolling turbo that features a substantial 50mm compressor wheel. This design ensures maximum boost at the top end of the RPM range, making it ideal for track, off-road, and extreme street applications. The large GTX exhaust turbine complements the setup, delivering extra boost at high RPMs and preventing torque loss compared to the stock K03 turbine.

Whether you seek extreme track performance, drag strip dominance, or unrivaled street upgrades, this turbocharger is the perfect choice. It offers impressive torque and durability, outperforming many other options on the market. To fully unleash its potential, we recommend pairing it with one of our aftermarket exhaust systems.

It's important to note that to harness the additional power, a custom tune is required. Running without a tune will result in minimal to no HP gain.

Estimated Power Gains:

• Approximately 60hp with a tune, intercooler, downpipe, cold air intake, new plugs, basic maintenance, and carbon blasting/cleaning.
• 120hp or more with all the above modifications, plus a ported head, larger valves, ICE pipe, intercooler, and a 3"+ or larger exhaust system.

Extreme GTD Upgrade Features:

• Brand new turbo!
• 47mm billet compressor
• High-flow GTX exhaust turbine
• High-strength K04 internals
• Upgraded 360-degree bearing
• Designed for higher pressure
• High-temperature alloy turbine housing
• Dual-scrolling turbine housing
• Water-cooled bearing housing

For engine and turbocharger reliability, JMTC recommends a 3.0" or larger downpipe/exhaust size for the GTD turbochargers. Please avoid using the stock downpipe or stock-sized catalytic converter.

The OEM intake boot can be used with the removal of the inner sleeve for N14 engines. For N18 engines, the OEM boot at the turbo connection will need to be heated and expanded slightly, which can be done with a heat gun. This turbocharger also fits AEM intake, NM Eng intake, and Forge Intake (Boot). Please note that the hose might need to be warmed and stretched over with a hose expander.
