The History of the Modern JCW Tuning Kits

This bit of information was part of the recent JCW press release from MINI UK but we felt it deserved it’s own published post. It’s a great way to take a look back at all the various JCW products throughout the years.

What’s in a name?

John Cooper Works under the ownership of BMW Group

The Cooper name originates from John Cooper, an engineering legend inextricably linked to the golden age of British motor racing throughout the 1960’s. With the introduction of new MINI in 2001, the Cooper name was reborn under the guidance of John’s son Mike, who began developing aftermarket tuning kits for the new MINI at the original John Cooper premises in East Preston, West Sussex.

In December 2006 BMW Group acquired the rights from Mike to the John Cooper Works Brand. Early in 2007, this transaction became effective and gave BMW Group the opportunity to develop this sub-brand and strengthen the MINI brand and product range.

The deal was agreed with the then owners of the John Cooper Works brand and in 2008, Mike Cooper remains as a consultant on the BMW Group’s John Cooper Works brand strategy. Mike has been involved in the design and production of the aftersales tuning kits available for the MINI Cooper S.

Although no longer producing their own tuning kits or accessories under the name John Cooper Works, Mike Cooper’s Cooper Car Company develops and supplies car accessories for various other corporate clients. The Cooper Car Company supplies BMW AG with hardware components for the current MINI Hatch aftersales tuning kit as well as sports air filters and sports exhausts for the BMW 3 Series. These parts bear the name John Cooper Works or BMW Performance respectively.

No formal cooperation agreement exists between the Cooper Car Company and BMW AG but given the successful relationship forged between both parties, it is planned and desired that the Cooper Car Company will be a partner of BMW AG for many years to come.

John Cooper Works tuning and MINI since 2003

The John Cooper Works tuning brand is a developing MINI story. Prior to the launches of the Oxford-built MINI John Cooper Works and MINI CHALLENGE cars in 2008, a line of aftermarket tuning kits and factory-built models plot the history of John Cooper Works back to 2003. In 2008, close to four thousand John Cooper Works-tuned MINIs are on UK roads.

    Great info Gabe, thanks! When do you suppose we can update the info above to include the Stage 1 Clubman kit?? :-)

  • nuvolari

    Hmmm. So, this seems incorrect to me.

    From what I know, the original 03-04 dealer-installed kit did NOT include an upgraded air filter or larger injectors. Just an new SC (with then upgraded rotors), ported cylinder head, plugs, exhaust and ECU update.

    The kit was enhanced in 7/04 (US) to include the air intake and larger injectors, along with a new tune to take advantage of these. That is where the 10hp difference came from. This upgrade to 7/04 specs was available to purchasers of the v1 kit at a surprisingly reasonable price from the dealer.

    This later kit became the factory option available for 05-06, with the exception of the exhaust being welded in place at the factory and including a restrictive crimp so that it would be compatible with the Cabrio’s rear end.

  • Edge

    I concur with nuvolari above.

    Also, the list is missing one small but still very significant kit:

    The JCW Tuning Kit for the MINI Cooper

    (Note: This was for the R50 Cooper, not the Cooper S… and it pre-dates the JCW Tuning Kit for the R53. It’s also distinctly different than the JCW Sound Kit for the MINI Cooper that was listed above)

  • nuvolari

    Edge, maybe we should start a Mini site. These hacks obviously don’t know what they’re doing. :)

  • MINIAC

    The 200 PS kit was announced in April 2003 but the kits didn’t reach US dealers until June.

    The 210 PS and Upgrade kits were announced in October 2004.

  • greg

    Nuvolari. I never heard of a “restrictive crimp” in the JCW cabrio exhaust. Any idea how it can be “uncrimpted”?

  • Charlie

    Greg, It can’t and still fit under the cabrio. The crimp is there to allow the exhaust pipe to fit next to a cabrio-only body-stiffening brace.

    JCW Coupes, even the GP came with the crimp–even though it wasn’t needed to fit–because MINI didn’t want to offer two separate JCW exhausts.

    You can have a muffler ship remove the crimp and weld in another section of exhaust pipe.

  • MINIAC

    The torque listed for the 200 PS kit should be:

    • 240 Nm peak torque at 4,000 rpm
  • Jon

    Nice to see this all laid out, good work Gabe.

    JCW has always been a point of interest with me.

    Though I have to say this story pretty much has me wondering about Mini’s future.

    “A larger Mini platform by 2015″

    Looks like the ever growing size of the Mini is still underway.

  • nuvolari
    Nuvolari. I never heard of a “restrictive crimp” in the JCW cabrio exhaust. Any idea how it can be “uncrimpted”?</blockquote I don’t believe it can be, if you have a cabrio. If you have a coupe, it probably could be through some creative torch work. My preference is a pre-cabrio dealer-installed JCW exhaust with the front resonator section replaced with a straight pipe (MyMini offers a nice piece). With that you achieve a true “rorty” exhaust note. :)
  • nuvolari
    The 210 PS and Upgrade kits were announced in October 2004.

    My bad on the date, thanks.

    I remember driving a dealer installed 200HP JCW R53 S back in the summer of 2003 and that car put a huge grin in my face. To me that car felt “right” like any other factory R53 should have felt and driven (This was before the 2005 “Facelift”) from the get go. To me the bone stock pre-2005 R53 S felt a little lethargic from the get go and the original JCW kit addressed some of the annoying acceleration issues the stock Cooper S of the time had.

    Believe it or not, I have never driven a 2005+ JCW R53 S, dealer or factory but I just can’t even begin to imagine how sweet those cars must be in comparison to the original pre-2005 200HP JCW cars.

    I still think 1st gen R53 JCW cars (Including the GP of course) will be very sought after vehicles in years to come and the factory versions will command premium prices in the used car market.

    I just bought a used 2003 Mini Cooper S from a Mazda Dealership in Oregon. I was surprised to find a complete JCW tune kit installed. There was no mention of this in the advertising. How much would it have cost to put this in. Thanks

  • Greg

    Brian:

    At the time (circa 2003), the dealership where I sold MINI charged $5,400 to install the kit. I live in OH, and it is important to note that prices vary greatly from coast to coast. If you’d like a more current price, simply pick a dealer from miniusa.com, call the service/parts dept. and pose as a 2003 MCS owner who wants to install one.

  • Wallace

    I hope this site is still active, because I have just the question for you guys. I am looking to purchase a used 2005 R53 in the US. The photos show an engine cover with the JCW engine cover and tag that says JCW tuning kit #xxx, and there are JCW emblems everywhere including the brake calipers. When I checked the VIn with the local MINI dealer, however, they told me the VIN did not correspond to a JCW vehicle, just an R53. How is this possible? Please reply to my email if possible. Thanks so much,
