Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.

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.

The JMTCs S45 F56 turbocharger was designed with the street and track enthusiast in mind. We started with our huge 50mm compressor and upgraded quick spool high flow turbine to give you full boost quick and a huge amount of power at the top end. We also designed it to maintain the quick response of the original turbo but deliver much more torque and power.

This turbocharger not only delivers high torque in the low to mid-range but you will also see a power increase at higher RPM. No torque or power loss like you see with the original small 43mm turbo. If you are looking for a great street, track, or strip upgrade that delivers full race performance this is the turbo for you. Don’t be left at the starting line by any other car and get one our S45 turbos today.
