Here is the downside of manual converting...
My revs seem VERY high when cruising at motorway speeds in 5th.
If you want to make good progress, the economy is non existant on the motorway :(
Anything I could do with the Diff to improve this? :-\

Aren't the diff ratios different between auto & manual ...... :-\ :-\ :-\

I was under the impression the manual diff would make it rev even higher, I may be wrong....
The only other point to note, is that I have some play, somewhere. Can't work out if it's box, or DMF
Most noticable at higher speeds, if you let off the gas at say, 70mph, a couple of seconds later it feels like some slack is taken up, and there is a little "tug" in the drivetrain. Then when you re-apply the gas, there is a another jerk, as the drive is taken up again.. :-\
Now the novelty has worn off, I am finding myself getting cross with the manual box a little more often... it has a long throw, and to get a smooth gearchange you do have to take a little time, which loses lots of power... I reckon realistically, I could get away easier in the auto, even though it is a beast in manual form... :-\

maybe you drive to fast ;D ;D ??
btw if you get diff of early 3.0 manual then your revs will drop down by 300rpm at 5th gear
what sort of rpm you have at 70 on 5th gear at the moment??

I thought you was going to say you cant eat a bigmac while driving. ;D

Possibly Serek!
At 80mph, it's sat half way between 3000 and 3500 rpm...

As said many times ::) ::) ::) why have more pedals than feet? ::) ;D ;D ;D ;D ;D

thats about right for 3.2 manual with 3.9 diff
if you want get few more MPG then go for 3.7 but wont be lot differents I try this before
-
Why not fit an autobox James ::) ::) ;D ;D ;D ;D ;)
-
As serek says, 3.7:1 is they way to go. According to Mr Haynes it seems that the manuals are all 3.7.

3.7 ???
you will loose acceleration ..

you will get used to it.. but if you really want a short shift , you need a sports tranny and lots of work :-\

Pish :P
My ex plod 3.2 manual, running its original gearbox and 3.7 LSD will pull 0-60 in sub 7seconds, even with a slight misfire and 225k 8)
Wheel size will make a slight difference to the cruising revs. Bear in mind that the MV6 and Elite wheels with 235/45/17 tyres have a smaller roling radius than the 225/55/16s, meaning they'll be spinning faster at any given speed :y
If mine was doing 3250 rpm at 80 I'd be wondering if the clutch was on it's way south ::)
Swap the diff if it's that big a deal :y
Gear changes can be done fairly swiftly, just don't rush between 2nd and 3rd, as that will really wind it up.

I cant get in and out of the back seats quickly enough (for selecting 2nd and 4th) to rush changes in a manual Omega :-X ::) :D

where you found info about 3.7 dif was fitted to 3.2 ex police cars??
-
Jimbob iirc :-\ certainly, it was confirmed that it left the factory with LSD fitted :y
Also, as discussed in another thread by Zirk, 70mph is 2600 rpm, 80mph is just below 3000. :y
Never had any real problem with belting through the box, just need to be sure that the clutch is still all the way down as you come out of neutral, especially into third :-X
Do the manual boxes all contain the same gear ratios :-\ if not that might be part of James' problem :-\

same car -same engine with 3.9 or 4.10 will easily beat you ;D

Perhaps :-\ but without an lsd, it'll be all smoke and noise ;D

I love my LSD...

That's the trade off. Acceleration will be less if the gearing gives a higher top speed, which the 3.7 will do.
As it us now though, or even more so with a 4.22 as in my auto, the top speed will come up much quicker if a little shorter and make the car a bit more punchy out of slow speed situations. Revs are higher with a bit of cost in fuel. But with a manual you'll be stirring the box more rapidly too to keep up.
Depends what the owner wants out of life really.
It's a bit like taking a correctly geared track bike on the road. What makes sense on the track, with quick fire changes baa baa baa to top gear, makes no sense at all on the road. ESP on the motorway in a road bike situation where the high rpm would simply drive the owner barmy.
Does sound like the correct dif is desired.

with 3.2 manual its gearbox different not dif
have look at botom of this page for more info
http://www.senatorman.de/getriebekennzeichnungen.htm
gearbox R30 listed for 2.2dti same fitted to police cars
5th gear its longer in 3.2 manual
