Lightened Flywheel for MMT6 Gearbox
Discussion
Hi all,
Sorry to intrude on this forum - I currently own a Mondeo ST220 (3.0 litre Duratec engine), which I believe has the same MMT6 gearbox that is used in the Noble.
I'm looking to fit an LSD, uprated clutch and a lightened flywheel. I've found a Quaife LSD, the clutch, I could probably stick to OEM if an uprated one isn't found.
However, I can't find a lightened flywheel anywhere, so I thought I'd try in this forum. The current Dual Mass Flywheel (DMF) is very heavy and is very prone to failure, so I'd like a lightened steel or aluminium one.
Has anyone here fitted a lightened flywheel on their Nobles or knows of where I could get one?
Also, is the standard Noble flywheel a DMF one or is it light to begin with?
Cheers.

Thanks again.
It's so hard to find any mods for the Duratec engine and the MMT6 gearbox. A search of the various Ford forums has so far proved to be fruitless. I wish the ST220s had the MTX75 gearbox, which from what many Noble owners say, is a much better box.
Thinking ahead, I've got a feeling that some of the lightened flywheels may not work with the standard ST220 clutch...

Right, I think I'm getting somewhere now.
One of the US model of the Mazda 6 (pre facelift) uses the 3 litre Duratec engine and the MMT6 gearbox, exactly the same as the ST220.
I've got the part numbers for the Fidanza Aluminium Flywheel:-
For the MTX75 5 speed gearbox - 186251
for the MMT6 6 speed Gearbox - 186111
I found a US seller that also sells the above, as well as other decent clutches and flywheels - www.ultrarev.com
I contacted him and he's quite happy to ship to the UK.

Hi guys.
Sorry to bump an old thread, but I'm still looking for a lightened flywheel for my ST220. I didn't go for the Fidanza one as an owner who fitted it said that the idle was lumpy and the general engine noise became too loud.
A friend of mine was taking apart his Noble's 6 speed MMT6 gearbox. When he took out the flywheel I had a feel of it along with the Mondeo ST220 dual mass flywheel - the Noble one was at least half the weight of the ST220 flywheel.
So I'm thinking of fitting the Noble flywheel in my ST220 as it won't be as super light as the Fidanza and thus quieter.
His flywheel had a Ford badge on it and the following part number: F73A-6375-AA
As usual, Ford were absolutely useless and had never heard of such a part number.
Can anyone help me as to where I could purchase the flywheel and how much it costs?
Cheers

go on www.fordparts.co.uk. Mail the question with the part number. The guy who looks after site is amazing. He knows everything and replies weekends day or night. He has even sent me pictures of different parts so I can decide which one is mine. Sorry to bump an old thread, but I'm still looking for a lightened flywheel for my ST220.

Hi Guys,
No joy with the the Lotuscentre or Ford Parts.
Lotus centre said they have the flywheel in stock but wouldn't give me the part number as apparently, Ford doesn't allow Noble dealers to give them out.
However, with my friend we worked out that the original Noble flywheel is in fact the same as the Mondeo ST24 one!!! We're almost 100% sure on this. Lotus Centre wasnted around £250 delivered, but now I know what it is, I'm sure I can source one second hand (probably why Ford are secretive with part numbers lol).
I got in touch with a guy in the US who put the Fidanza flywheel in his Mazda 6 (with the Duratec engine) and he said the difference in responsiveness is amazing, with no problems with excessive engine noise, or vibrations coming through to the pedals.
So I'll probably go for the Fidanza flywheel now.
One point - when my friend put the Noble/ST24 flywheel into his ST220, he had to use the clutch slave cylinder off an ST24, as the original one was about an inch too short.
Questions:
1.) When you guys fitted the Fidanza flywheel in your Nobles, were you able to use the original clutch slave cylinder, or did you have to get another one to enable it to fit?
2.) Did the Fidanza fit with the standard sized clutch, or did you have to get uprated or different sized one?
3.) After fitting the Fidanza, did anyone experience lumpy idle, excessive engine noise, less smooth gear changes etc?
I appreciate your help as I think I'm getting somewhere with this.
