JM40 K03 turbocharger is engineered to be a reliable and high-performance upgrade turbo and works well with all OEM components. The JMTC's high-flow twin scrolling JM40 turbocharger uses an extended tip compressor to give you boost that starts early and last long. This turbocharger delivers outstanding response with torque and power gains across the entire power-band. It will deliver great torque, spool early, and last into the higher RPMs.

JMTC Dual Scroll Turbo and Cartridge

  • JCW/JM40 40mm compressor
  • Extended tip compressor wheel
  • High temperature alloy turbine housing
  • Twin scroll turbine housing
  • Water cooled bearing housing

SAVE $$$ whether you choose the new or refurbished units!!!  Borg Warner supplies their K03 Turbocharger units to MINI for these models. The refurbished units are completely overhauled including replacement of all internal wearable items such as Turbine Shaft Bearings and Steel Thrust Plates. After the rebuild all internal components are triple balanced which is one step better then the manufacturer's dual balance process. Any components that do not meet JMTC's stringent standards will be replaced. Some parts that are damaged beyond repair may be replaced with JMTC parts but will retain the full One Year Limited Warranty.

NOTE:  The lower coolant line will need to be 'flipped' 180 degrees to clear the wastegate shaft.

See the Turbo Application Guide to see all the options for replacement and upgraded Turbo's.

For Turbo related replacement hardware, see our Mini Cooper Turbo Installation Hardware Application Guide.

Maximize your power gains with the ECU upgrade from the supplier of these Turbo upgrades.

CORE DEPOSIT

Additional Core Deposit is charged with every Turbo order. Core charges are refunded when a 'Rebuildable' and 'matching' core from your MINI is returned and inspected by the manufacturer.

All or part of the core deposit may be forfeited if the core:

  • Is severely damaged and not rebuildable
  • Does not match the unit being purchased (ie. if you send a stock turbo and order a JCW unit, part of the deposit is foreited).

The amount of core refund is determined at the discretion of the Turbo Manufacturer.

IMPORTANT INFORMATION

Read the Manufacturer's Installation Requirements below - THESE ARE REQUIREMENTS YOU MUST FOLLOW IN ORDER TO VALIDATE THE MANUFACTURER'S LIMITED WARRANTY - NO EXCEPTIONS.

Some States (like California) have ever tightening requirements for emissions testing and inspections. Always check your local regulations on compliance for street use.

OTHER PARTS TO CONSIDER

Gaskets, seals, studs, and other hardware are NOT included. If you need to replace these items, order separately.

See our Turbo Install Kit. This kit includes all the most commonly replaced gaskets and seals, plus a new oil supply line. Additional gaskets, seals and other hardware may be required depending on the installation.

When servicing the Turbo on the MINI, it is very important (maybe even critical) that you replace the Turbo Oil Supply line to avoid potential future turbo issues.

Over time, the turbo and turbo supply line builds a fine layer of 'coked' or cooked oil on the internal surfaces. When you remove the supply line from the turbo, this disrupts the continuity of the coked layer with great potential of some of the coking to flake free. These coked oil particles can easily clog the fine journals that feed oil to the turbo bearings. Once the the oil flow is compromised, it is only a matter of time for cascading failures that can damage the turbo and catalytic converter! Don't take a chance - REPLACE the Oil Supply Line ! ! !

For additional protection, take a look at the Turbo Oil Supply Line Thermal Wrap.

For other TURBOCHARGER related products, see our TURBOCHARGER products page.

MANUFACTURER'S INSTALLATION REQUIREMENTS to validate Manufacturers Limited Warranty: 

  • Replace the turbo oil supply line with the turbo.
    • Due to excess heat round the turbocharger and particulates suspended in the turbo supply oil the oil will harden or "coke~ in the turbo and oil supply lines. If the oil supplyline is not replaced with the turbocharger the coked oil will break free from the side walls of the oil supply line and damage the turbocharger bearings. Cleaning the oil line will not help and only aggravate and increase the likelihood of the turbo failure due to coked oil breaking free form the sidewall.
  • Replace the catalytic converter on mini coopers before installing a new turbo.
    • The Catalytic converters in the downpipe and B pipe may look clear but if any oil leaked into it some of the holes might be blocked and will cause back pressure. This starts to happen on Mini Coopers at 15k miles! Exhaust back pressure causes premature failure of the turbocharger. Turbochargers are not designed to have pressure on the exhaust side. As an alternative, have your catalytic converter refurbished to restore original flow.
  • Prime the turbocharger.
    • No oil on the turbocharger bearings will cause failure of the bearings if they are dry even for a short period of time. Prime the new turbo with oil before you connect the oil lines.  For maximum protection, see Turbo Additive for Priming New Turbo's
  • Fresh engine oil with a turbocharger change
    • Perform an oil change with full synthetic motor oil at the factory recommended viscosity when you install a new turbo. Change the oil again after one heat cycle if:  the engine is brand new, newly rebuilt, or if your MINI had a catastrophic turbo failure.

MANUFACTURERS WARRANTY STATEMENT

Manufacturers Limited Warranty
covers all turbochargers to be free of defects in materials and workmanship for normal use and service up to 1 year (2 years if the oil line is replaced) after retail purchase. Manufacturer reserves the right to examine any part returned for warranty claim to determine whether a defect in materials or workmanship exists in such product. Manufacturer liability is limited to repairing, replacing or crediting towards other product, and credits will not exceed the invoice total for the parts.

Labor and storage charges are not products of the manufacturer and, therefore, will not be reimbursed for any reason. Final determination of the condition and suitability of the parts for uses contemplated by the buyer and is a sole responsibility of the buyer. Manufacturer will not be liable for any damage or injury to persons or property that might be claimed as a result of improper installation or misuse of any part subjected to this warranty. No warranty claim or refund, will be given until the item is in our possession and we have processed it which can take up to 20days.

Before installing any of our products it is the responsibility of the installer/owner to fix or resolve any and all problems that cause the original part/item to fail and can cause the new part/item to fail. Since we do not troubleshoot, we take no responsibility for incorrectly diagnosing the issue that caused the initial part/item to fail. There are no warranties expressed or implied beyond those set forth above.


OUR ADVICE ON DRIVING A TURBOCHARGED MINI

We STRONGLY recommend you change the motor oil more frequently than the factory recommendation. Anecdotal evidence suggests Turbo's with more frequent oil changes have fewer issues. We suggest 5000 mile oil change interval or less. Make sure you use FULL SYNTHETIC motor oil with the ACEA (Association des Constructeurs Europeens d'Automobiles) A3/B3 specification.

After a long or hard drive, drive 'easy' for a while just before your destination. This will reduce the engine and oil temperatures to lower operating levels. Also make a habit to let the engine idle for a couple minutes before shutting off. This will help cool the turbo preventing oil coking in the journals and bearings. Yes, the MINI has an auxiliary water pump that runs after shutdown to help cool the turbo, BUT - the oil isn't cirulating - it just sits there waiting for the turbo to cool. This is why we recommend you idle before shutdown - let the oil circulate while the temperature comes down.

Question:
I have a 2014 mini countryman S ALL4 with stock everything other then a muffler delete and a drop in high flow intake and my question is with this turbo upgrade does it use all the same hardware and even bolts up to the stock exhaust manifold? My other question is will this turbo make the car stutter and have issues especially when driving hard or will the car act the same as if it had the stock turbo? And would I need a tune for this? Will this turbo will operate like stock with a stock tune in all rpm ranges and throttle positions? Furthermore I’m assuming a tune would be beneficial for the car and for the turbo
Answer:
Yes, the G2NME2840R is a 'bolt-in' replacement. You can use the stock hardware and bolt up the stock exhaust manifold.
You shouldn't have any driveability issues

In order to get the most from this upgrade, you should upgrade the intake and exhaust to improve flow and reduce backpressure.
The JCW engine has a slightly lower compression to accommodate the larger turbo, your MINI does not. The JCW also has a different intake and exhaust and ECU software.
If you want to get 'JCW-like' performance, you will probably need to have similar upgrades to the JCW. The turbo alone will not achieve this although it should raise the boost pressure slightly.

Yes, it will operate like stock and an ecu tune will help the performance.
Please note the manufacturer's installation requirements on the product page to validate the warranty.

Question:
My turbo requires replacement due to a diagnosed waste gate leakage causing a sensor to detect this condition, causing the check engine light to illuminate. My question is, I’d rather purchase the refurbished turbo due to the lower cost. Does the refurbished turbo have its waste gate re-machined to ensure a tight seal?
Answer:
Yes, the refurbished turbo is reconditioned to meet new turbo spec's or better, so the waste gate seal is tight.

Happy Motoring
