Alfa Romeo 147 Q2 diff?

[dazrick68]

Looking at an 2003 Alfa Romeo 147 GTA with 60,000 miles. Its had a cambelt & water pump replaced at the last service, however more recently its had a new clutch fitted but & still running the standard diff.
Is this a problem?
How long will the standard diff last or is it a must to upgrade to the Q2 system?

Mines done over 70K on standard diff as far as I know.......I dont have any eveidence of it being done in any of the receipts prior to my ownership anyway.

No problems at the moment but I do have a low mileage spare, that I'll have fitted when the clutch gets done in the future.

Why would you replace the diff with a standard one?

I can't yell hard enough about how essential a Q2 diff is - not only from the improved power deployment, but the potential costs from a diff failure are HUGE, we're talking thousands. There's no warning either, it doesn't wear, it'll just go *pop*.

A low mileage one will have less wear than a high mileage one surely!

I got it cheap enough so might as well swap it if I ever need to do the clutch.

I know alot of people rave about them, but many also dont notice the difference after fitting one......suppose that could depend on the driver though.

Its been ok on the standard diff for this long so they cant be that bad anyway....and I can keep my money for when something else breaks!

Thats the problem though, it could happen anytime, and its not just high mileage examples. Spending £250 to potentially save thousands, while at the same time improving dymamics seems like a pretty good deal.
Not to mention that no punter worth their salt would buy a GTA without the Q2, or they'd at least want a discount to get it done....

Someone could get a cheap GTA with mine soon then, regretfully with a change in commuting arrangements I need to get something cheaper to run.....

A cheaper Twinspark or Jtd of some sort maybe......as I'm hoping to run 2 cars again, and one needs to be an Alfa!

It would sound good at £250 but I can't find a Q2 anywhere near that price. You are looking at a minimum of £500 fitted.
