OK so after reading through about 20 threads, most of them start of with different claims then usually after reading through the thread it would be suggested that the 2.6 / 3.2 Omega's came with the 4.22 differential.
So to clear up the air can anyone confirm one last time if the 2.6 / 3.2 Omega's came with the 4.22 diff from the factory? (or if other options were available from the factory?)
Thanks!

Standard ratio on 2.6 auto was 4.22:1 3.2 auto was 3.90:1
Manuals had the 3.90:1

Thanks, that clears that up. Also found this (http://www.omegaowners.com/forum/index.php?topic=90453.0) whilst randomly browsing the site which was helpful. Can't seem to find one for the pre-facelifts as a comparison though? Maybe its there and I'm just playing blind ::)
So in theory, having the 3.90 diff on the 2.6 would result in better acceleration?
-
higher the ratio compared to previous ,better the acceleration..
if its not manual , not worth bothering :D ;D

A high ratio is a low number.
So a 3.0 ratio is higher than a 4.0.
A high number(therefore a lower ratio) will probably accelerate better, but it is dependent on a bunch of other factors too.

I know but thats how producers number it.. :-\

Haha, ssshhh it will be an auto, so get over it ;D
According to this (http://www.omegaowners.com/forum/index.php?topic=90497.0) thread, the 3.45 diff teamed with an auto kicks some serious ass!
What about cruising RPM's though? I wish they had done some tests @ 120kmph whilst conducting those readings. I'm assuming by swapping out a 4.22 with a 3.45 you would see much higher engine load when cruising.

Other way around.
The 3.2 is over geared. It runs out of puff at about 130.
Fit a 4.2 dif in the 3.2 auto and it will accelerate quicker, rev on past 130 and feel more lively.
It will also rev 3-400 rpm higher at cruising speeds though, and fuel economy suffers slightly.
-
Problem is the 4.2 dif is already the quickest accelerating dif available.

nope.. 3.45 is worst ..check carefully :y

Agreed. 3.45 with a petrol engine will be terrible - tractors only. ;D
Also, remember that those graphs show theoretical speeds in gears. If the engine doesn't have enough grunt to get there it won't happen.
4.22 in a 3.2 auto is probably a worthwhile mod, as the auto is quite high geared. (mine is far from bogging down at 130, mind.. apparently) :-X
4.22 might be a bit much in a manual, as that is lower geared anyway, and the low gears in that gearbox are already pretty short, IMHO. IIRC, someone on here tried it (after a 2.6-3.2 conversion) and went for the 3.9 after trying it.
2.6 manual might benefit from a 4.22, but the auto already has it.

I suspect I may have a rumbling diff, this is a perfect excuse to fit a 4.22 diff! :y
So a 2.2 or 2.6 should have a 4.22 diff ?

2.6 have a 4.22 but not sure for 2.2.. :-\

My 2.5 diff has a leaky pinion seal.I have a spare 3.0 diff (both auto cars) which I could bung in there rather than change the pinion seal.Problem is,I dont know what ratio aeither a 2.5 or 3.0 are. :-\ ;D
Might be best to just change the seal I suppose. ::)

2.2 auto or manual, and the AUTO 2.6 have a 4.22:1 dif.

Thanks MV8 ;)
Kevin, I'm guessing by your post you have a 4.22 diff. Is the difference noticable?
-
i have fitted a 2.5 diesel diff to my 3.2 manual and it drives fine and i was getting 28-29 mpg out of it and a higher top end
-
Don't diesel diffs have different ratios than petrol and are tall geared for economy?

Nope. I haven't done it to mine. Purely a speculative comment. IIRC Chrisgixer did it and was happy with the difference it made. ;)
Then again, I once asked him what impact it had on fuel consumption and he gave me a funny look which told me he really didn't care much. ;D

4:22 for the 2.5, 3:90 for the 3.0.
And before you ask ::) ;D

Cheers Rob. :y
2.5 is already sluggish.Im thinking the 3.90 diff would make it even more so. ;)

Go on a diet then fatty ;D ;D

Its the bloody car that needs to diet.Its half a ton overweight for the power output. ;D

Chuck that heavy LPG tank out then :D

But then I would need to fill the petrol tank which holds a lot more liquid than the LPG tank. ::) :P
