ve sv6 diff

[astroham]

ok so i have just been informed that my diff is f'd ... great (my fault though i guess) ... so i am looking at putting a better diff into the car ... any suggestions on what brand / ratio to go

just to clarify i have a 6sp manual sv6 ve ... i know there is other threads on this but all i could find was people recomending manual ss diffs for autos ... are the ss diffs stronger than the sv6?

the stock diff in the SIDI's is an LSD 3.27 ratio I think from memory, so just look at replacing it with one of those. I'd honestly just look at replacing it with a second hand diff of the same ratio or like a SS diff 3.45, just make sure it's LSD.

I'm pretty surprised the diff gave way though, surely thats a Holden warranty job??

Think the standard diff is LSD in the ute but is a single spinner in sedan. I've a 3.27 single spinner with only 5000kms on it if you are interested PM me. If you want a better diff I'm running a 3.7 LSD in mine and it is excellent....about $1800 brand new from Holmart.

To give you some ideas,
I saw an LSD 3.27 on eBay a month or so back that went for around $500 with 70,000Kms on it.
I just purchased a 2.92 LSD from a Clubby with 80,000Kms for $380.
(Berlina and Calais V8 models dont get LSD as standard, hence the reason why I just bought, and about to fit a LSD version soon).

Here is a rough guide as to what diffs were fitted to what models...
Please dont take it as gospel, Holden had LSD as an option on a lot of these models, and Holden did make many running changes over the life cycle of the VE.

3.6L Alloytec Dual Fuel LPG Engine - 4 Speed Automatic - 3.27 Non LSD Differential
3.0L SIDI Direct Injection Engine - 6 Speed Automatic - 3.27 Non LSD Differential
3.6L SIDI Direct Injection Engine - 6 Speed Automatic - 3.27 (Optional LSD on SV6 Models)
3.6L SIDI Direct Injection Engine - 6 Speed Manual - 3.27 LSD Differential
6.0L V8 L98/L76 Engine - 6 Speed Automatic - 2.92 Differential (LSD Standard on SS, SSV Models, optional on Calais, Calais V)
6.0L V8 L98/L76 Engine - 6 Speed Manual - 3.45 LSD Differential

HSV Automatic Models - 2.92 LSD Differential
HSV Manual Models - 3.45 LSD Differential

What happened to the 3.7 in the HSV manual???

Destroying a diff in a V6 Commodore? WOW!!! That takes some serious driving (or just small amount of dumb).

[Jarp]

Soz for the misinfo didn't realise the LSD was stock on the manual 3.6 SIDI.

Did you have many problems with calibrating the new speed on the 3.7 diff Jarp?

I did initially but both CHE and MACE can recalibrate the speedo now although the MACE fix is more accurate according to my GPS.
