2006 Mini Cooper S JCW - Not Broken...Yet

Hi guys, I have been promising a few of the Mini guys on here that I would share what I have done with my John Cooper Works over the last couple of years and what I am doing going forward.

The car is an R53 Mini Cooper S John Cooper Works. It is a mid 2006 car and is one of the last R53’s made, as production then moved onto the R56. I wanted an R53 mainly due to the charging element, supercharging on the R53! Turbo on the R56. Easy decision for me.

Here is a brief spec/overview of the car:

Hyper Blue,
Chilli Pack,
Visibility Pack,
Chrono Pack,
Chrome Pack (yuck),

When I got the car it was full of cobwebs, sap, mould etc and cosmetically is a mess but for me the mechanicals are more important, cosmetics will be done in time. It was nowhere near as bad as Jbenekorrs find ! But his was free haha

Here are the Pictures of the state of the car and its first detail:

All that chrome will be going!


The wheels are in need a of good refurb, all four are pretty much like this.


Mould everywhere


More mould


How about some more gunk


The "Viper Stripes" are growing one me


This chrome is wrank


Front bumper has an annoying alignment which I will sort


Cack and bird muck for good measure


Doesn't look that bad...


...oh no wait, more cack


Lets make those wheels bleed - BH Autowheel


Obligatory snowfoam pic and it may have even been a Sunday!


Lots of embed brake dust


BH Autofoam working a treat!


Here is the engine bay...more on that to come...including the GRS Motorsport Cooler


Very dusty


Clean wheels, although refurbishment required!


Worst after shot ever but I was knackered and the paint is horrendous so it didn't warrant any proper after shots. I have another update on the paint condition!


I have spent a fair amount on performance upgrades that I will show in the next update, some if it isn't well documented as it was done by specialist and before my time on the forum, so I wasn't keeping up with photos etc. My more recent upgrades and tidying up are and there is lots more of that to come.

I have to apologise, my camera skills are shocking!

Hope you enjoy.

Part 1 - Background and Upgrades

So as I mentioned in the introduction post, I have done a lot to the upgrades of the car but not documented it very well but here is what I have had done:

Quaife ATB Differential
New driveshaft seals,
New sump gasket,
New thermostat,
New belt tensioner,
Gearbox oil change,
New clutch release bearing,
Denso IK22 Iridium Spark Plugs,
Magnecor KV85 Spark Leads,
Eibach Front and Rear Anti Roll barm
Powerflex Front Wishbone Bush's
Powerflex Gearbox Mount,

Alta 17% Reduced Supercharger pulley with new 1360mm belt,


Vibratech Engine Mount - Which hasn't lasted long, the rubber is perished already!


Pipercross Air Filter - Which I thought I would clean up


Out came the filter which was covered in bits and dirt



Apology's for the dark picture but I wanted to remove the actuator that opened a flap at 3500rpm for "more noise", well to me I wanted more noise all the time so out it came

Just left with the hanger now which isn't causing any harm


Cleaned out the airbox as it was full of debris


The filter was well oiled, what do you think haha



GRS Motorsport Cooler




Another thing wrong with the car is that the bonnet cables have stretched so they don't actually release the bonnet, but when I eventually managed to prize it open but stripping it out of the release and yanking it with a pair of pliers I had to great a washer, and seeing I wasn't at home this was the best thing I could come up with haha s


Also inspecting under the bonnet, I found the top mount has failed, and gone right through, please say it hasn't mushroomed the top mount!

Here is what it should look like (Drivers side)


And here is what a knackered one looks like (Passenger side)


Well it should give me something else to do!

Thanks for reading, the next update will be the fixing of the top mount!

I have also had the car Dyno'd, with the following figures:

Before upgrades listed above:

195hp @ 6,700 rpm
165lb ft @ 5,100 rpm

After the upgrades:

211hp @ 6,600 rpm
188lb ft @ 3,300 rpm

Difference

+16hp @ 100 rpm earlier (+8% Power Increase)
+23lb ft @ 1,800 rpm earlier (+14% Torque Increase)

You can't half tell the difference on the torque, pulls like a train from low down as you used to have to rag the nuts of it to get it into the powerband. You still have to do that now but it drives how it should from the factory.

The standard JCW kit took the normal Cooper S upto 200bhp, however Mini did release an additional upgrade kit that took it to 210bhp, but I don't think mine has that option.

I am still yet to determine whether I have the "JCW Sound Kit" which gave +3bhp and which had an uprated exhaust and a sports cat, mine does have an uprated exhaust but I'm not sure how to tell.

Here are the before and after Dyno graphs.




Thanks for reading.

Nice project you've got there and the power looks strong.


Regarding the "Chrome Pack" as far as I am aware all R53 models had chrome on the exterior as standard, as do most BMWs even now. There was a Chrome Pack for the interior (My own R53 had it, called Chrome Line Interior, Option S345A) which added chrome rings to the dials, the base of the gearstick and around the cup holders.

Also, I am no expert but I thought R53s came with colour coded boot lid handles. Mine certainly did and it had had a chrome one retro-fitted when the original failed. I then sourced a colour coded one to get it back to OEM spec.

For what it's worth, I don't understand the dislike of chrome trim on cars generally. I know in Audi land you can choose a "black pack" but I'd still prefer it without, especially on cars in darker colours. You need the chrome to break up the lines.


What are your plans with the chrome though, cover it in vinyl?

Thanks mate

As far as I understand it James, the “Chrome Pack” consisted of the interior code pack you mentioned and chrome boot handle, scoop, upper and lower grills, but I could be wrong there as I am going off research from un-cited sources shall we say. I may do some more digging.

The majority of the chrome has been replaced with colour coded new BMW genuine trim pieces and then the black “hex” grills on the front.

I will add some pics in the next update.

I've not even read this yet but YES YES YES and again YES!




Edit:

Ok I have now read it and composed myself... Looking forward to more updates of its progress over the last couple of years. That really is a late one! It looks like a good car. Apologies if I have missed it, but what mileage does the car have? It seems to be quite similarly optioned to mine - Hyper Blue, white roof, Chili Pack, Chrono Pack. I wholeheartedly agree with you that some of that chrome needed to go. I'm no chrome hater, but that is TOO much

To clarify on the JCW packs (or at least just muddy the waters with my limited knowledge...) yours being a later one should be a JCW 210, the difference was up-rated injectors (they are blue rather than beige). I think this came in during late 2004. Mine, being a mid 2004 is a JCW 200 and has the beige injectors.

The JCW sound pack was an option for the Cooper only I believe. Yours seems to have the correct JCW stainless steel twin exhaust and I will take it as a personal insult if you have not polished up those backboxes

How much of a noise difference did you notice when de-flapping your airbox? I did mine before I ever started the engine so I don't know! There's some serious induction/supercharger noise!

The mileage is 89,000 mate, it does around 2000 a year as it is my weekend toy car and I really want to keep the miles down.

Yes you are correct I think I got myself confused when I typed that post. In 2005 the JCW kit was updated from the JCW 200 (bhp) to the JCW 210 (bhp). After speaking to a few people in the trade, the 210’s never made 210bhp, the highest known is 205bhp on production ones (the prototypes did but it took a lot of fettling). So when I first got the dyno done I was disappointed and what lead me to the assumption the +10bhp must have been an extra, but after research and what you have said it seems it was standard.

Haha yes I found that out the other day the JCW exhaust is brilliant.

The grunt is definitely noticeable on the airbox, sounds ace and the exhaust backfires a treat. I have polished the exhausts but the tips get filthy after one drive as my car is burning oil. The back boxes are in good nick and I will try and get you a pic.

Next update will be the interior, then the top mount change, followed by the big brake upgrade. It just takes me a while to write them as you have set such a high standard now!

Yes the updates do take a while don’t they! I think your dyno run before the mods is a very healthy number, I’d be interested to know what mine would make, but also probably very disappointed now that it’s just ticked over to 149k

Mileage on yours is good - it’s got to be a keeper
