Hey guys, I search all over the internet and can't find anything about this.
My brother bought an used R56S 07/2007 German car, we bought it thinking it would be a N14, but yesterday when the car's papers arrived on the mail, on the engine number it shows: N16 6. I couldn't believe it cause I thought the r56s came only in the n14 and n18 configuration.
So we went and checked the engine number on the block, and surprise surprise, it says N16B6.
How is this possible?
What are the differences between what my brother has and the N14/N18, is the N16 better, worse?
Please let us know.
Thanks!
welcome to the forum. The N14 and N18 are the ones with turbos. The exhaust tail pipes come out from the middle and on the trunk there is "S" after cooper. The N12 and N16 are the base engines. N14 is found on 2007 to 2010 hardtop and up to 2012 for the JCW. N12 is found on 2007 to 2010 except 2007 and 2008 convertibles. N18 and N16 are on 2011 to 2016 (HT to 2014, Clubman, convertible, til 2015, countryman and paceman till 2016)
check bimmer.work or the decoder in the forum to decode the car. also, post pix of the engine bay.

Thanks for the reply, this is not my first r56s Im sure that it is a Cooper S...
Thats why I am so surprised it's a n16, that's why I am asking this.
We bought the Turbo not the Justa, that i am for sure, top side the engine looks like the n14, but on the engine plate its shows what i posted... N16...
As MiniToBe said, run the VIN to find out what the original build had. European models may have different configurations than US. Cargusjoh may be correct, see realoem.com to see if the N16 and N14 blocks are interchangeable.

Ran the VIN, comes out N14...
But on the car's registration(documents) says:
Make:Mini
Model(Version) :Cooper (S)
Power: 175hp
Engine Code: N16...
What you do you guys think?
Original Engine blew up, they used N16 Bottom end and N14 top end?
The car runs perfectly fine and pulls strong, 0 problems at all, barely burns any oil maybe even no oil burn whatsoever, but we just found this so strange...
Didn't find any thread on Nam or other forums about N16 MCS...
That is weird. Only thing I can think of is to talk with a dealer and see if the serial number on the engine matches the VIN from the original build. If not then you have a rebuilt engine - not necessarily a bad thing, with all the issues the N14 had.

I have a R53, I know that the Cooper and Cooper S are the same engine apart from the valves being of a different material because of the r53s Temps.
My question is...
Is the N16 bottom end the same as the n14, as in, is it made to handle the cooper S Temps and boost?
if this is the upper half of the short block, I'm afraid some modification were done on it. The N16 by design does not have the inlet for the turbo oil feed line and it does not have the oil jets to cool the pistons. IF this is the lower half of the short block, then no worries since they both are made of the same material. I suppose the bearings were replaced to match proper journal clearances.

The upper part looks like n14, the bottom part is definitely a n16
I'm not referring to the cylinder head as upper part. I'm referring to the part where the cylinder go up and down in (aka upper half of the short block).

OH okay! Is there a way of checking that without opening the engine?

There are two things to check. the first is if the pistons are from an N16 or were changed to N14. for that, you can insert a camera in the spark plug hole and observe the shape of the piston. N16 does not have an impression in the middle unlike the N14 piston. you can google images so you know how they look. The second test requires removing the pan, oil pump, and may the oil baffle plate to be able to see the oil jets.
I just looked at my engine...the engraving is in the lower half of the block. So usually when vacuum pump seizes, the timing chain ends up chewing the dip stick opening channel. Maybe that's why this engine is half breed.
Based on a sticker on the windshield and the dealer stamps in the service booklet (as seen in the pictures posted on fb), the car has at some point been registered in Germany. This would also explain the winter grade tyres it is equipped with while on sale in Portugal. You may be able to contact the dealer who did the maintenance work and enquire there.

Yes that's exactly the car my brother bought! The dealer imported the car themselves.
So my brother is the first real owner here in Portugal.
I'll try calling the German shop and see what I can find out!
