hi all

i recently purchased a 04 reg reg 147 gta. it had new gearbox / clutch in november 2009 due to a damaged diff! the mileage was 54K.

the total bill is for £2600.00 ( i have the receipt) from an alfa specialist, would a q2 have been fitted, is there any way i can tell this.

do i really need a q2? if not fitted already.


regards

It probably depends on the owner at that time. However a new gearbox on it's own, if it really was new, would easily cost the £2600 fitted plus a clutch. I hope you're lucky and it has got a q2, but you can get one fitted for about £500-£600, I think others on here will reccomend you get it done as the standard diff on a GTA is a known weak point anyway.

Check the breakdown on the invoice, they would have clearly listed it but I doubt you have one at that price.

You really do need one, there are loads of threads about blown diffs and the 147 GTA is more prone to blowing than the 156 GTA. Not only will it prevent it blowing again it wil help with traction, its not going to completly cure the torque steer but its very good and my traction control light hardly ever comes on at all now unless I'm being an total :shake:

The total bill when my diff went was something like £3000 including a Q2 so I agree it probably wasn't done.

It is an expensive job to do but I have not heard of a Q2 popping as yet whereas the number of standard diffs which popped is significant. I wouldn't say it does much about torque steer but it does do a very good job at getting rid of most understeer and transforms the dynamics making the GTA a much more accurate drivers car. In other words you should buy it on the merits it will prevent a big expensive gearbox failure and then be glad you did because your car is so much more fun to drive

Who was the alfa specialist?
Give them a call and ask

If not then give Ned at Autolusso a call, they have fitted more Q2's than anyone else I know!

Q2

Is there not a "safe" test that can be done to check whether an LSD has been fitted? Surely with the Q2 fitted it shouldn't be possible to hold one wheel stationary with the other spinning (driven by the engine), but this should be possible with an open diff?

Not sure how you could actually do this without risking injury though! Images of car jacked up being driven off jack in my head don't look pleasant!

Handbake on, chock rear wheels, put the front on 2 axle stands, start it up and put it in first. Then go and grab one of the wheels :lol:

Simples!

Try hitting a large roundabout far to fast. If the nose stays fairly tight with the asr off and you can feel a super natural force at work it has a Q2. If it drifts wide you will die and there will be a article in the paper about some twit in an alfa having a crash but at least you will die knowing

come on dont be silly - a q2 doesnt work with a wheel off the ground :cheese:

it must have been a plated slippy diff you tried that on previously

 

[Oggy_GTA]

Aw come come now! On tickover, I don't think it would take his arms completely off ...

 

[marcevo1]

look at a q2 as a £600 insurance policy..... great bit of kit as well for the money

I'm typing this with my nose


The best way to check if it's got the Q2 is to let someone who's experienced both diffs have a go of your car. :thumbs:
