After last week’s Ask MotoringFile marathon, we realized we still have a couple more that needed to be answered. However for today’s edition, we’ve got some professional help. The question comes courtesy of Dustin:

>Is the R53 JCW kit a good idea to refresh your higher milage stock MCS? Providing that the R53 JCW engine kit still available at dealers (which I don’t know if it is or not, or how long MINI plans on producing them if they are) It would seem that the new head and SC fitted to a MINI at say the 100K mark would make the mechanicals sound for the next 100k (since the expected life of the SC is only 150k), plus the new HP would breathe new life into a car for a loyal owner.

Great question Dustin. While we like the JCW upgrade for the R53 quite a bit (and the R56 for that matter) we’re not sure if it’s the best solution if the car isn’t under the factory warranty at this point. Especially considering the cost. So in order to give you a good picture of your aftermarket options, we’d like to turn over this question to Eric Savage, owner of the renowned MINI tuner Helix and longtime friend and supporter of MF. He also knows a thing or two about brewing beer, but that’s a story from another time. Anyway, to the Eric’s answer…

The John Cooper Works package has always been a popular option for new MINI buyers for a couple of reasons: it has the prestige of a factory tuned car, and it carries the factory warranty. As far as I know, retrofitting the JCW kit on an high-mileage car does not extend the warranty on the car (or the new parts, for that matter) which makes it less attractive for the high-mileage MINI owner. The big knock on the JCW package has been its nearly $6000 price tag once installed. It is for that reason that companies such as Helix Minisports has made a living tuning our favorite cars. We can do what the JCW package does–and much more–for substantially less money.

The JCW package consists of a new supercharger (with smaller pulley), a lightly worked cylinder head, an intake, injectors, software and exhaust. All of these parts play well together to produce a fun boost in engine performance, if not an M3 eater on the highway. What I typically recommend is to address the performance of the total vehicle, so that you can easily dispatch that M3 in at least the twisties. Simple is always safer when tuning MINIs, so I’ll typically make two recommendations, one performance package that will accelerate with, and out-handle a JCW upgraded car, and one that will leave the JCW car panting. (Both can be put together and installed by any of MINI focused aftermarket tuners you see advertise on the pages of MotoringFile)

Package #1:

– Upgraded rear sway bar
– High quality summer performance tire
– 15% reduction supercharger pulley
– Free flow intake
– Good ECU tuning file

Your total cost including installation should run you about $1800 depending on who sells the parts and does the installations.

Or you could go for what I like to call the Full Monty in Package #2:

– Upgraded rear sway bar
– High quality summer performance tire
– 15% reduction supercharger pulley
– Free flow intake
– Good ECU tuning file
– High flow cylinder head
– high flow complete exhaust system
– high temperature street/track brake pads
– high temperature brake fluid

Package #2 could cost you approximately the same as a JCW kit, but in return you’ll get a car capable of laying a MINI smack down on everything but the most expensive sports cars, and you’d leave the JCW car in the dust, all while retaining excellent drivability and reliability. All of these parts are of course sold a la carte by any number of shops, so that you can tailor the car to your specific needs and desires. Be sure to speak to an expert to be sure that all of the performance parts you are considering work well together. And you can always contact me below.
