GTV 3.0 V6 lightened flywheel

Hi all,

With my GTV V6 rebuild project finally coming to an end, I'm toying with replacing the clutch before fully returning it to the road. Is there much merit in throwing out the dual mass flywheel and replacing it with a lightened one at the same time?

I've seen the EB spares and alfaholics kits (autodelta are too expensive), but does anyone have any other recommendations?

If I can afford it I'll probably go for the Q2 as well, but it may have to wait for that.

Thanks

Re: GTV 3.0 V6 lightened flywheel

Yes it is worth getting rid of the DMF.

It is not essential to have a DMF for that engine or gearbox as the 156 2.5V6 & the GTAs don't have DMF.

Don't bother with a special lightened flywheel, just use a std 156 2.5V6 or GTA flywheel.

Would a 156 2.5V6 or GTA flywheel be lighter than the standard then? confused?

The 3.0GTV DMF is around 14.4kg

A 3.2V6 156/147/GT/GTV flywheel around 8.1kg
A 2.5V6 156 flywheel around 8.6kg

That's great, thanks

Any ideas where I can get a GTA(etc) flywheel and clutch kit to match it?

Cheers

Re: GTV 3.0 V6 lightened flywheel

It would be easier to find 2.5 fly and clutch. I did that on my gtv and it's much more responsive.

Re: GTV 3.0 V6 lightened flywheel

Nice work Alan, that's pretty much what I'm planning. Luckily I don't have the cats to deal with though.

This may be a stupid question but I'm guessing I'll need the clutch for the corresponding model's flywheel I get? Or could I use a gta clutch with a 2.5 v6 flywheel and would there be much point in doing so?

Re: GTV 3.0 V6 lightened flywheel

Many 2.5V6 owners fit the GTA clutch as it often costs less...

Re: GTV 3.0 V6 lightened flywheel

You can't use a 3.0 clutch kit with a 2.5 or 3.2 flywheel, but you can use a 2.5 clutch kit on a 3.2 flywheel and vice versa.

I would buy GTA clutch kit, and then either 2.5 or 3.2 flywheel whichever is cheapest.

Mine has the DMF in

Re: GTV 3.0 V6 lightened flywheel

We sell the GTA flywheel and clutch. Andrew put one in his car and we compared the weights of the two when they were out-chalk and cheese!

He reported that the engine is much more responsive without the DMF as the lighter weight allows it to spin up much quicker.

Worth doing if you're replacing the clutch as with DMFs you really should replace these at the same time.

Re: GTV 3.0 V6 lightened flywheel

Thank you, sure about that, cause it's very difficult to have the information, the only thing that I'm sure is the clutch mecanism is the same as the spider 3,0l V6 12s...

The Spider 12v 3.0v6 doesn't have a DMF either.

Re: GTV 3.0 V6 lightened flywheel

Ok, thanks a lot David, now I need to find if I can adapt a GTA clutch kit or if I have to change the flywheel (If it's possible).... Too many problems I need to upgrade the clutch cause I change for a little bigger TB.

Alfa GTV 3.0 V6

GTV3.0 v6 1999 5 speed

So I rang EB spares and they are all happy about GTA fly wheels etc until I mention mine is a 5 speed.
After reading through lots of pages about this subject and also the fact that clutch has died i am going for the following setup:
2.5 V6 clutch kit
2.5 v6 or GTA flywheel

Will this work on my 1999 3.0 v6 5 speed GTV?

Thanks for any info.

Yes, we've done this already on a customer's car. With a Q2 diff too

Q2 diff

Thanks for the assure on that one.
I now have bought a second hand flywheel and clutch will be on its way next week.
What advantage does a Q2 diff give?

GTV V6 2,0 L TB

Just test it on a trackday last sunday on the superb track on Mas du Clos. Amazing after corner the car turn in very good condition of grip like you've got the new super tyres and 200kg less... It seems never slide from the front even if you put foot down... And I've got old falken tyres in 205... Just amazing for the GTV

Q2 diff totally transforms the way the car drives, see here for a description:

YouTube - Alfa Rmeo Q2

Also, it is much stronger than the standard differential, which is known for sudden failures and the tendency to fire pieces of itself through the side of your gearbox. Failure usually costs 1200-1500 to fix, Q2 diff supplied and fitted is 600.

Do a search on here for 'diff failure' and you can read all about it, scary stuff. There are so many people who have suffered diff failure already, my car included.
