I've had my Cooper S for about 3 months now, got it 2nd hand from Sytner in leicester. Is it possible to get the JCW conversion done on a car thats done 60K or is it only available for new cars? also what kind of power gain can I expect? (its a 2003 163BHP version).

Bhozar · Feb 25th, 2007, 04:51 PM

The big advantage of a JCW conversion was the two years waranty it had from BMW. With the car being as old as mine I would just go for a GTT conversion for half as much and for a little extra power.

JCW will give you 210bhp for £3k+. GTT can give you 220bhp for around half the price.

No reason why you cant get it done to a 60k car at all.

ScottyBoy · Feb 25th, 2007, 05:08 PM

The best thing to do is go with some1 like GTT as mentioned half the cost! and ive had discussion with people who believe the JCW to be more like 195 - 200BHP rather than 210BHP

as idnt have a JCW i cant sayjus what ive talked about with people who haev!

Bhozar · Feb 25th, 2007, 05:12 PM

I have a JCW, but went to GTT to get the power upped a bit more. If I had known about GTT before I bought my JCW MCS I would have bought a standard MCS and gone directly to GTT.

the JCW will give you engine warranty again

sef · Feb 25th, 2007, 05:29 PM

I was thinking the same... Went to a rolling road day with a standard S to see what I'd get... I got 193.1 at the fly wheel a friend with an S works got 189.4... A remap has got him to 198bhp... I've been looking at GTT too and for the money you certainly get more...

Interesting Concept if true.

Although I`d definitly go for an aftermarket supplier, (I went for the Lohen conversion), the £2500 saved on not getting a JCW conversion would easily pay for a replacement engine to be fitted if anything did ever go wrong, which is very rare if only upgrading to around 210bhp.

Tigger, Eeyore & Roo · Feb 25th, 2007, 05:39 PM

Just been to GTT for the first time (for a strut brace) and they make some really nice stuff.

I'd actually feel much happier letting Roland at, GT Tuning, loose on our S than handing it over to some main dealer service mechanics that I can think of!

Go see Roland...

The JCW conversion costs £3000 for just the parts, to have it fitted by a MINI dealer will cost another £600 at least in labour. This IMHO is just too much money on a car with 60,000 miles. You could have it fitted by someone else of cause, but it is then regarded as a aftermarket kit, so best to just go to an aftermarket tuner to start with. A 210bhp kit from GT Tuning will cost £816 fitted. A 220bhp kit will cost £1170 fitted. Makes a JCW conversion look very expensive, and the JCW wont add any value to your car at all.

JAMIE1131 · Feb 25th, 2007, 05:56 PM

Thanks for info guys, quick responses! The reason I'm thinking of JCW is that I got the car from a MINI dealer and have the Cherished MINI warranty which is pretty comprehensive and offers unlimited mileage. I don't wanna blow the warranty by going somewhere else. I'm guessing the MINI engine is probably good for around 200K (any one got this far???) so it should have enough life left in it to handle 210BHP but I would wanna push it too far. I guess it would probably need a new clutch soon though!

Haggi · Feb 25th, 2007, 05:56 PM

JCW is a good conversion - its just hideosly over priced for the power gain imo esp if your cars getting on GTT is defo they way to go as said the GTT 220 is half the price of the JCW

sef · Feb 25th, 2007, 05:58 PM

For 3K at GTT you could get some serious kit... The strut braces look excellent too... (Especially the black one) Just need to talk my wife into letting me have it all done...

Rakey · Feb 25th, 2007, 07:34 PM

I'd do the same as what everyone else has said, head down to GTT with a car of that mileage and age.

Not there is anything wrong with the JCW conversion.

I had a very similar conversation with Roland at GT Tuning last Friday. Mention your concern to him, he has a way of ensuring that your warranty can remain in place.

My MCS had nearly 38k miles on it when I made a 1100 mile round trip to get the GTT treatment.

Their products are of superb quality and the service matches that as well - save yourself some money and go the GTT route - you won't be disappointed!

JAMIE1131 · Feb 26th, 2007, 06:19 AM

GTT it is then folks! they must be good if so many people are recommending them!!

Mike Clarke · Feb 26th, 2007, 06:40 AM

Most replies are focussing on the power increase for the price paid and so recommend GTT. Using that reasoning you should just buy a smaller pulley and do the changeover yourself, even cheaper than GTT and just as much power.

What you really need to do is get full details of what is included in the JCW upgrade and the GTT upgrade and do a proper comparison, there is more to this than just bang for buck.

Check out the Engine & Drivetrain Tuning forum for more options and opinions.

I went the MTH Tuner file route and have no idea how much increase in power I got and it really doesn't matter as I know what it feels like to drive.

A new pulley is just part of their upgrade (even that they make themselves and it's a work of art!) Without a well thought out remap of the ECU at the same time, the full benefit of most hardware changes can't be properly exploited. Yes, it would be undeniably cheaper still, but it wouldn't give "just as much power" as the GTT220 conversion that many of us are recommending.
