2nd Gen JCW Most liked posts in thread: R56 JCW has a different turbo than the MCS?

Even if the only course is dominate hardware, as opposed to superior skills, it is time that "mini_racer" and "Gene Driving Machine" domination of H2R for mini's comes to an end. Thy reign shall fade into the sunset. Fear the GreyLenz! Each day it grows stronger. Each run off the track makes it tougher. Each lap it gets faster. Fear it!!

 

Hey GreyLens......
With your massive bump in engine power, it's also important to make sure your brakes can do what's expected of them. Any plans for a comparable performance increase in braking?

 

To be honest, I do not possess the skills or the tires to claim domination. I don't have to dominate though......just as long as I am faster than you.

 

That's SICK!!! and that can only be achieved with a JCW? I hope the JCW Countryman doesn't take too long to be produced! How much would a tune like that cost?

 

I thought the JCW dealer installed kit had been discontinued. If it has one could buy the JCW intake & exhaust & get a Jan tune. Seems to me that would be the easiest thing to do to get an R56 up & running well. At least without springing for the factory JCW.

MM brakes will only slow you down.

 

I have a tune FMIC and exhaust, I plan on upgrading to the jcw turbo. Unlike popular belief, the only difference **engine wise** between the fact. jcw and the mcs is the pistons produce a lower compression ratio. They are both forged pistons, both heads and blocks are the same etc., obviously there are different peripherals but other than that they are the same. A few folks have upgraded and been able to get better numbers but with higher stress levels with the MCS due to the 1 point or half a point higher compressions ratio. I will see if i plan to go through with it because depending on the difference in flow, i wonder if i can get the same power with less boost

 

From the Press Release:

• Upgraded/Optimized Turbo Pistons and four piston brakes (adapted from the MINI Challenge race car.
• Upgraded Air Intake (same as dealer installed kit)
• Revised 6 speed Manual Transmission
• Upgraded Clutch

It would be fairly easy to prove/disprove BMW's claims. Do you honestly believe that BMW would intentionally mislead in this litigious society in which we live and risk a massive loss of reputation? Trust me. Nobody would want to take a hit like that.

 

Hi,

Would anyone happen to know the difference between the JCW upgrade ( mini website cost is $2100 or so, and that seems to be w/o labor) and this upgrade:

JCW John Cooper Works Tuning Kit for 2011+ - Way Motor Works

why the significant price difference? Parts seem to be the same, but I could be wrong...


thanks!

 

Hi borv,

They are the same kit. $2100 is the MSRP, and Way's price is discounted. Note the orange tag at the upper right ("SAVE 14%") which computes to exactly the correct amount.

 

The press release is correct, but so is Bigprfed22's statement. Bigprfed22 simply only stated the differences in the 2 engines as that's what is pertinent to the topic at hand. The press release gives some details about the whole car.

 

Thanks RKW,

Does the kit come with any exhaust modification? This kit seems a bit different than the one on the mini JCW part of the website for official MINI accessories.


Seems like (on Way's website) the official Mini kit but with headers and a k&n filter? Or does the official mini kit also come with headers?

 

I could not agree more ! There seems to be some misinformation from parts shop and various articles (I had commented to a quoted article that more or less was making this erroneous point in detail on another thread) that just through bolt on aftermarket parts you can make the "S" engine into a JCW. That is completely and totally false ! Can you bring a just newly bought "S" to match a newly purchased JCW in strait whp ? Sure, no prob and that's great ! But to think it's the same as a internally worked and built, factory JCW is just fooling yourself. I was going to get an "S" and aftermarket the hell out of it .. After doing the real math both in money and in power gains I came to the conclusion IMHO this was totally the wrong way to go for the $ ! People might balk at the initial price of the JCW and look at the WHP output and say well I can mod a "S" for a little more then half the upgrade price and achieve the same WHP. But when you consider the truly massive Moding and tuning potential of a factory JCW there is no comparison none frankly. And after I added everything up I realized that the engine internal upgrades that are the JCW are really an absolute total bargain ! I am shocked there are MINI owners that think otherwise. Think about it. A larger more efficient turbo, larger reinforced pistons, larger better built manifold, Brembo front brake package, reworked ecu, far better suspension package...ETC ! For only 6k to 7.5k (USD) more on a thirty thousand dollar car !? I dare anyone to match that in the aftermarket. It can not be done ! And that in the end made all the sense in the world to me to wait the extra 3 months and get a JCW. I just knew I would be kicking myself if I hadn't.

 

Engine internals... :nonod:

Engine internals are the same except a half of a point lower compression.

 

You are incorrect. Somewhere on here are the engine specs and if I remember correctly the pistons are different ......someone help me out here!

 

Which is where the half a point of compression comes from:crazy: same material same head gasket and internals...:beer

 

According to RealOEM the pistons have different part numbers. What the difference is, beats me.

Rods, bearings and crank are the same.

Heads have different part numbers, gaskets do not. There are no listing for parts such as valves and cams so that is hard to tell if they are different. Then again, different valves and/or cams may be the reason for the different part numbers for the head.

Turbo and exhaust manifold have different part numbers

 

According to Bentley

JCW Summary of changes are as follows.....

Only components that were needed to achieve higher performance and a more sporty sound were modified.....

Cylinder head gasket revised in terms of heat distribution, resulting in improved coolant flow.

Cylinder head wall thickness changed in some places in relation to water jacket to remove local peaks caused by increased performance.

Improved intake valve seat material and extra-hardened intake-valves.

Strengthened piston side faces, and adapted to reduce compression ratio of 10.0.

Charge air pipe improved to reduce pressure drop.

Intake air filter with integrated mass air flow sensor.

Turbocharger adapted to changed conditions.

Turbocharger and exhaust manifold materials adapted to higher exhaust gas temperature (about 30 degree C higher).

Catalytic converter two-stage design.

Red Brembo front brake calipers with 17" wheels and 12.4" brake rotors.

Appearance and acoustics, plus specific sound impedance of exhaust system were improved to create a special sound.
