Questions about R53 factory JCWs

When did they start, and what differences were there compared with the MCS? I'm guessing exhaust and ECU, maybe the Brembo brakes. How about the supercharger and pulley? I saw they have 200 HP, and cost about $6500 more, which is about the same as my car over the 2014 MCS. Did they have a bodykit like mine? Thanks in advance, I'm just interested is all.

The factory JCWs started being manufactured in November of 2005 (2006 model year).

The 210 bhp tuning kit included:
Machined Cylinder Head
Supercharger with Reduction Pulley (multiple sources claim a 11.4% reduction pulley)
NGK BKR7EQUP Spark Plugs
JCW Cat-back Exhaust
JCW Air intake
380cc Fuel Injectors
ECU Remap
JCW Intercooler Cover
JCW Front and Rear Badges

http://minicooper.wikia.com/wiki/1st...JCW_Tuning_Kit

In addition to the 210 bhp tuning kit, the 2006 factory JCWs also received the larger JCW front brakes (rear brakes were not changed) and a limited slip differential. The JCW suspension kit and the JCW aero kit were independent of the factory JCW option. My 2006 factory JCW does not have the JCW suspension kit or the JCW aero kit.

The factory JCW option in 2006 was option code 3AL.

For what I know about the JCWs (R52/R53) they are JCW add on kits that were installed at the dealership.
The JCW Engine kit basically included:
Ported Head
Spark Plugs
JCW Supercharger
Air Box and filter
Exhaust System
Fuel Injectors
Pulley Belt
Assorted hardware, brackets, gaskets, Badges, Covers, and certificate
And the ECM would need to be FLASHED
And I have seen that they rated a range from 200 to 211 HP

There were also suspension kits, limited slip differential, brake kits, and body kits (exterior and interior).

In 2008 ... Model Year 2009 MINI offered the true Factory JCW version, and they worked in all the models within a few years.

My 2004 R53 (MC40 #211) has the Engine Kit and the side skirts from the body Kit
My 2007 R52 has everything but the body kits (exterior and interior).

I just want to add that there was a factory optioned JCW available in model year 2006. This was the only year a factory JCW was available for the R53. From what I have read, the factory JCW was 210 bhp and the dealer add JCW kit was 200 bhp. After October 2004, the dealer installed kit was 210 bhp. Here is where I got this information:

200 bhp dealer JCW kit (pre-October 2004):

210 bhp dealer JCW kit (after October 2004):

All JCW KITS from 2005+ gen1 (factory or not) were 210 HP ...all factory 2006 cars got that...
Kit was the same as dealer. But you got the BBK kit tossed in...
Net result was a 2006 with a dealer add on or factory kit WAS THE SAME if you added the BBK kit to it...but the factory kit WAS more convenient, let's face it..it you were gonna go JCW, might as well get the BBK and the LSD...
Some dealers gave you back the old parts...and getting a used exaust, head and SC was a big plus for many...heck that is WHY many got the kit...many made extra $$ by assigning a core value to this stuff...
But "dealer takeoff" zero mile heads and SC still pop up for sale....some mechanics put the stuff away, and are making some $$ off it.

The confusing part is older pre 2005 cars (2002-2004) got a 200 HP kit...coated SC, etc...but a updated ecu in 2005, with an extra sensor made 210 feasible with slightly bigger injectors (JCW 380's were on the 210 kit only)...the 210 kits also got the ice CAI...
Older cars COULD BE UPGRADED From the 200 to 210 but the extra cost for 10 HP was not very $$ effective...
Then add that the lack of the extra sensor ment it was mostly a timing advance with more fuel on the 2002-2004 cars....
The only thing a "factory JCW" gen1 gets you saying it is factory...the same car could be made with the dealer kit in 2005...orr even 2006....just comes down to $$$.

Thanks guys, that's interesting. So whether or not it was done at the factory or at the dealer came out the same. Supercharger, pulley, brakes, head, exhaust, intake, ECU=210 HP. I assume the cost was $6500 either way (someone had that on the sticker or his factory job). Interestingly the cost is still $6500 but you get the body kit and no exhaust, plus piston upgrade and clutch. I'd rather have the body kit lol.

The factory JCW Package (which included the 210bhp Tuning Kit, JCW Sport Brakes and LSD) was originally listed as a $6300 option. The rub is it required the $1400 Sport Package. In Europe the JCW Package came with 16" Bridgespoke wheels, instead of forcing you to option another package which included (17") wheels which cleared the larger JCW brakes.

The 200bhp JCW Tuning Kit originally retailed for $4500 (plus 10 hours labor). The JCW Upgrade (airbox, 380cc injectors plus remap) was originally $525 (plus 1.5 hours labor). The 210bph Tuning Kit was originally $4775 (plus 11.5 hours labor). The dealer installed JCW Brakes originally retailed for $1056.

The Aero Kit for the 1st Gen MINI was not a JCW branded accessory

I recently stumbled across an 2004 40th Monte Carlo edition with the full JCW engine mods you have listed as well as a full aero body kit. Is there anyway to tell if this car has LSD. Thanks

LSD wasn't a factory option (2TA) until January 2005 builds.

^^ this was a top find for the MC40, most dealerships when they got the, one per dealership at the time. Loaded them up with JCW bits and stuck them in the showroom floor and marked up the price. I seen a couple like this. But they are a rare breed. This was back in late 2004 when i got my new MINI.

Thanks for the info ECS and SKurj. My car is a 40th, was one of those loaded up on JCW options at the dealer. Don't know if I have the LSD, but I have the BBK, airbox, suspension, aero kit and etc. I'm assuming it has the LSD, but I guess the only way to tell is if the transmission is opened. I do know when I really get on it, it tracks straight and no noticeable pulling to one side or the other.

Welcome.

Yea, most likely it does not have the LSD , that was in 2005 builds. Most MC40s were late year 2004 builds, but sold as a 2004. It was like the Mc40 got a late start in 2004.

vin decoder will tell you if you have the LSD, it's unlikely as mentioned by ECStuning
