How Do I Know if My MINI JCW Has an N14 or N18 Turbocharged Engine?

December 20, 2016

The late model turbocharged MINI 4-cylinder engines, used in the US market Cooper S and JCW (John Cooper Works) models, are produced in two variants; the N14 and the N18. The use of either the N14 or the N18 engine is dependent on the production year and there should be no confusion …. except for the 2011 & 2012 model year JCW variants.

Why should you know whether your MINI has an N14 or an N18 engine?  There is some overlap in the use of both the N14 and the N18 engines in the 2011 & 2012 MINI Cooper S JCW models and various engine parts are not interchangeable.  When ordering engine, emissions, fuel system and some other parts, you will need to clarify if you have the N14 or the N18 engine.  Failure to do so may very well result in the wrong parts being ordered.
