R56 That sucks, can't afford to get rid of my MINI...
BTW, a 135i similarly equipped to a $41k JCW will cost $50k.
the JCW engine has a few small changes, 10:1 compression vs. the MCS 10.5:1, supposedly stronger pistons, as for bolt-ons, I believe the injectors are different, the MAF is different, turbo's slightly different (housing appears the same), different turbo inlet pipe, different programming (up to 19psi boost and the euro burble), different bov, and the exhaust has no 2nd cat ...
.
.
Mini actually did their homework on the JCW this time. Just found this from "MOTORINGFILE" dated July 2008:Engine tuning The 2008 International Engine of the Year (1.4-1.8-litre category) found in the MINI Cooper S was a strong base unit on which to begin John Cooper Works tuning. The basic structure of the engine - a pressure die-cast aluminium crankcase with grey cast-iron liners and bed plate - has not received any modifications. Nor has the forged crankshaft or conrods.
The intake valves and valve seat rings have been upgraded with more durable materials to withstand the increased temperature caused by the free-revving engine. The pistons have had their sidewalls reinforced, which means the compression ratio is reduced to 10.0:1. The cylinder head has similarly had its wall thickness increased to reduce any localised stress or hot spots when running at peak output.
Air supply is improved through fitment of a larger air mass sensor and charge air line, meaning greater throughput of clean air and a reduction in the loss of throttle power. Induction is quickened through a larger air intake, in turn meaning the car’s maximum 280Nm torque figure is 20Nm over a standard MINI Cooper S.
At the exhaust end, a strengthened and larger twin-scroll turbocharger and exhaust manifold are central to performance improvements. The material used in machining the turbine has been upgraded for the Works engine, with maximum charge pressure increased from 0.9 to 1.3 bar. A high temperature can therefore be preserved for longer in the combustion chambers and helps the car achieve its remarkable peak torque figure.
The catalytic converter and rear part of the exhaust system are increased in size to aid the unrestricted flow and reduction in back pressure of exhaust gas, which minimises potential power loss or delay. Turbo lag is therefore virtually non-existent.
In addition, the transmission has strengthened gearing to handle the extra available power. This helps to give the car a remarkable output of 132hp per litre, yet still able to offer a staggering 40mpg.
Dang
At least until I install my new BV Cosworth head, new cam and get my Mynes tune
no, bore is the same, otherwise the displacement would have changed.
I've been unable to find a PDF for the JCW similar to this one issued when the R56 was released.Attachment 41226

That is correct, sure would like more specs on the turbo though. It says it is larger, wonder by how much?
there is no way a 135 will keep up with a mini in the twisties... JCW or not.
Even if it were the same price, I'd still get the JCW.
All my vehicles are paid for except my mini. It's an '08 MCSa with 20K miles . I paid 31K+ and took a look at my payoff.... after a year, it's still 29K+.
I really wanted to buy a new JCW and even at 41K, payments are roughly 70 bucks a month more than I'm paying.
Sad part is, not only can I not get 29K for my car, I bought and installed JCW stage I kit, JCW big brake kit, JCW ground effects, JCW coils among other stuff.
After modifying cars for almost 30 years, I understand you can't get your money back from mods but I ain't even close to getting payoff without that stuff.
Oh well, guess if I want the JCW, I'll have to really take a beating on selling my car.

$41k for the JCW? What on earth did you put on it?I just optioned one out, exactly to what I would want, and this was the breakdown:
R56 JCW Hardtop: $28,550
Pepper White/Pepper White: $0
White Turn Signals: $100
Xenons: $500
MFSW: $250
Rear Fogs: $100
Total: $30,150.
That's a hell of a car for $30k. It's literally got everything you need (and some) to thoroughly enjoy it. Any other options added on are fluff and could easily be replicated or bought from Morristown MINI for much cheaper. Labor is cheap when you DIY.
You've already got the JCW aero kit. Do you have the original bumpers? If not, look to buy a set used (You could probably get them for $200). Installing those yourself is a simple task and doesn't even require putting the car on jacks.
The BBK package will bring good money in this community, assuming you still have the original brakes. The coils probably will too but honestly, they're not even remotely worth the money. Piece out the Stage 1 kit to help recoup some of the cost.
This is all easily doable. Step back and ask yourself if you really need the extra $11k worth of extras you added on that's different than what I listed. Do you really need a sunroof? Automatic A/C? I think this is something you could easily work out and still have an excellent car.
I should tell you what I didn't put in it.... it would be a shorter list...lol.
Nav, sirius was the biggest expense.
Here's my listing.

HELL YA.... I need that stuff...lol. The JCW doesn't come in automatic. I don't remember clicking on sunroof. I do want the nav and xm. The problem is with the low interest rates, my payments aren't that much more.
Oh well...

Awe man, I'm in the same boat mate. I just fell in love with a Midnight Black JCW, and I already have a 2007 MCS. I think I'm in a better situation though, I owe less than what the car is worth so I should actually get some money for it when I trade it in. My optioned out JCW will probably be around 37k. Around what my MCS was. You definitely have an amazing spec'd car! :-)
Hope you work it out so you can get it! Good luck!

Well if you buy your accessories from Morristown MINI, they sell all their accessories at I think 20% off automatically, so that saves you something like $800 just from that.
If you aren't planning on using the stock rims, you could always sell them in the marketplace for some good cash. I still think you could reuse your current JCW aero kit at the very least. You could also probably convince them to install your current coils on the new car when you trade the old one in.
Just remember that everything you add before you pick the car up means that you won't get the stock parts back unless you specifically ask for them. Keeping those is key to getting some of your money back from mods you've installed when you sell the car.

Getting parts isn't an overly big deal. I own two bodyshops and get 25% off parts. (not to mention that I have some good friends in parts which really hooks me up on stuff I want... I bought my JCW stage I kit for 1335 bucks)
I called the dealership, I'll see what kind of beating I'm gonna take.

They were referring to the automatic climate control, not an automatic transmission.
Checked with two different dealerships today. The most I'd get on trade in was 20-21K.
I still owe 29K.
Guess I'll be keeping my '08 for a while longer....lol.
Tis okay, I love my car, I was just dreaming.

I think you'll find the JCW turbo really isn't all that and that the stock MCS pistons can handle much more than the standard output of the JCW. Many people on here were already running higher boost & bigger HP/TQ numbers with a Unichip, the trouble with the MCS is the lack of a proper reliable reflash.
You can always order the JCW turbo as a simple bolt-on, but for the $1800 or so (pn#11657583149), there will likely be some nicer aftermarket offerings eventually.
That would be one sick JCW Cooper!
I drove the 135i (was thinking of it as my next ride) but it just felt... dead. It was no fun to drive, although wicked fast. I'm thinking Evo X (or XI if it comes out), but for now, the MINI just owns all. The upgraded engine in the JCW has got to be great for tuning!
To the guy who said with a tune the Cooper S will kill a JCW... what about a JCW with a tune?

I never understand the "with that much money you can go buy X instead". I mean if I had enough money to buy a space ship to fly to work, I would rather spend that money on a MINI. Only a MINI is a MINI. This isn't the "I couldn't afford a XX so I bought a MINI instead, help me make the most of it" forum.
