Important Notes:

• The turbocharger does not include an electric actuator; use the one from your old turbo.
• For optimal results, consider refurbishing your OEM catalytic converter or using a high-flow downpipe. Installing a new oil line is also recommended to prevent future issues.
• Turbocharger rebuilds include a complete overhaul and replacement of any worn or damaged components, with a full warranty on rebuilt parts.

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 135/535 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 135 or 535 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.
