MINI COOPER TURBO INSTALLATION HARDWARE APPLICATION GUIDE


Servicing the turbocharger in the 2nd generation Mini Cooper S models can be very challenging.  There are the standard replacement parts that should be replaced when servicing the turbo, but there are also many other hardware parts that become unusable during dis-assembly, or you find them corroded or damaged and require replacement.

This Application Guide lists most of the common turbocharger related hardware that you 'may' need, along with a few upgrades that you may wish to consider.  Click on the image or title to see more details on from product page.

For Turbo replacements and upgrades, see our Mini Cooper Turbo Application Guide.

 


Install Kit

This kit includes the ABSOLUTE MINIMUM of parts you should replace when servicing the Turbo.  It is critical that you replace the Oil Feed Line is included in this kit since the old line will have 'coked' oil that can break free and clog the oil journals in the turbo.

Exhaust Gasket and Seal Kit
 
A convenient kit with factory exhaust gaskets and seals.


Oil Line Kit

Turbo oil feed line and return line.

Oil Feed Line Heat Shield OEM

Some of the earlier models did not have this factory heat shield for the oil feed line.  If your Mini does not have this, add this and/or the aftermarket heat shield


Oil Feed Line Heat Shield Aftermarket

This is an aftermarket version of the heat shield for the oil feed line.  Use this or the factory heat shield.  For best results, use BOTH!

Downpipe Studs

Exhaust studs rust very easily, and the extreme heat makes these stud very difficult to remove.  If you damage the original studs, these are the factory replacements.

Manifold Studs and Nuts


Exhaust studs rust very easily, and the extreme heat makes these stud very difficult to remove.  If you damage the original studs or nuts, these are the factory replacements.

Oil Lines

Turbo Oil Lines and related hardware available separately.

Coolant Hoses

As with any coolant hoses, replace these lines as soon as you see 'cracks' in the rubber or any leaks. 

Auxiliary Water Pump OEM

This is pump that circulates coolant through the turbo, even after you shut down the engine.

Vacuum Lines

If you have vacuum leaks causing rough idling or reduced power, check these lines.

Reinxoadd Turbo Additive / Priming oil

The turbo needs to be primed during installation to ensure that it has the proper lubrication at initial startup.  This additive is specially formulated as a primer for the newly installed turbo.


Diverter Valve OEM

The diaphragm in this factory diverter valve has been known to occasionally fail leading to loss of power.  This is the factory replacement, or you can install one of the upgraded versions. 

Diverter Valve Upgrade

This diverter valve upgrade produces sharper throttle response and uses higher quality materials than stock.

Exhaust Clamp

Factory replacement clamp to secure the exhaust system to the downpipe.
 
Cooper S Downpipe OEM

If your turbo failed with white smoke out the exhaust, you should replace the downpipe since your old cat is contaminated and clogged with oil.  This creates back pressure which will cause problems with any new turbo.
 
Milltek Downpipe Upgrade

Larger diameter downpipes allow the turbo to spool up faster.  This is almost a necessity with oversized performance turbos.  Unfortunately, these aftermarket downpipes are only for off-road Minis and not legal for street use.
