has anyone here built 1 of these to drift as a play toy :y
or what do people recomend for lowering springs an whats the max you can get also has anyone eva used camber adjustment bolts if so are they any good?
ive already welded the diff and stripped out the rear of everything!
-
is this on the road use or other regarding the springs?
-
its road legal still but may become track drift only as i dont want to mess up my rx7 lol just need to get it down :y
-
road use i think there are after market springs which will lower 40mm without any issues..
-
Just had a look and yeah looks like thats about as low as springs will take it as nobody sells 60mm
-
Shocks are already adjustable for camber.
-
Theres one for sale on ebay http://cgi.ebay.co.uk/Vauxhall-Omega-3-0-MV6-Manual-Drift-Track-Car-LSD-/180560521144?pt=Automobiles_UK&hash=item2a0a3ee7b8
-
I've seen that 1 but I already own 1 lol and the shocks are camber adjustable? Not really took it to bits yet. How does that work then
-
That track Omega would be good for a laugh :P
-
Mines pretty much the same but for driftin as it's got the welded diff an they are fun and a well built car
-
You can get -60mm springs, i had a set on mine, and ran on 17s with full interior without any scrubbing at all.
But ive just changed the back ones with volkswagen golf mark 4 tdi springs (also -60) because they are alot stiffer, which is what you want for drifting. And these worked a treat.
Dont waste youre money on camber bolts, when you lower it 60mm the rears lean in alot anyway. and i just keep the fronts normal.
The next think you will want to get for drifting is the diff from a 2.5 v6 AUTO from after 1998, which is a much higher ratio (4.22) compared to standard 3.0 (3.70) and weld that. This transforms the car and makes it much easier to break traction.
-
Where did you get the 60 from mate and I will try find a auto diff an what diff is the 2.5 manual
-
I owned that car for 2000-2007 and for a few months this year,probably the best omega I have owned with plenty of life left in it.........
-
i dunno where my springs came from because they were second hand, but they are definately -60, because i measured from the floor to wheel arch on each corner before and after fitting. I am pretty sure they are PI though, and i have seen them on ebay before.
I THINK that the manual 2.5 v6 diffs are 3.90
The 4.22 is definately the one to go for. acceleration is transformed and the car now hits the limiter in top gear at 149mph
-
cool i wil try find 1 thanks

mine was go up only up to 145MPH on 4,22
-
It depends on the size of the wheels/tyres as well, bigger wheels = higher speed.
-
i'm planing to replace a 3.7 diff on my mv6 with shorter one. either 3,9 or 4.22.
what can i expect in means of acceleration, RPMs at 60mph, fuel consumption?what do i get?
-
These figures are what the car will do with each diff fitted, at the redline/6500rpm, using the r28 gearbox fitted to 3.0 mv6's
(NB. This was calculated with the car running 195/65-15 tyres fitted, figures will be SLIGHTLY higher the bigger the RR is, but not a major differance)
3.70 diff (standard mv6)
1st 35 mph
2nd 63mph
3rd 100mph
4th 133mph
5th 165mph
3.90 diff (pre 1998 2.5 auto)
1st 33mph
2nd 60mph
3rd 94mph
4th 126mph
5th 156mph
4.22 diff (post 1998 2.5 auto)
1st 30mph
2nd 55mph
3rd 87mph
4th 117mph
5th 144mph
-
Car is revving at just under 3000rpm, if i remember correctly,
Fuel consumption isnt affected too badly as long as you stick to legal speed limits, but then again, consumption cant bother you too much or you wouldnt have bought an mv6! :D
My girlfiend lives 12 miles away, and if it reset the average cons. and sit at 60mph all the way, it is around the 34mpg mark.
Acceleration is the most noticeable improvement, the car really wakes up, and is much more responsive.
This is my personal opinion, but i hoesntly believe its one of the most effective - cheap mods you can do on an mv6

yes...this is what i'm looking for...
my opinion is that standard gear ratio setup is to high...it is great for autobahn, because 100+mph accelerations are great. but, if you live outside of germany, this feature isn't that useful, because of all the speed limits on motor ways and civil cop cars.
on the other hand, the car is rather lazy in urban driving (sub 40 mph) and sometimes not up to a challenge of beating boy racer cars.
my previous car, 2.5 v6, was an automatic (4.22 diff). when the gearbox died, we put the manual one in, but kept the auto diff. Accelerations were astonishing, with great flexibility, especially in lower speeds.
i'm certainly going to fit either a 3.9 or 4.22 diff. i know i will lose some top speed, but i am not using it anyway, because of all the civil police interceptors cruising the motor ways just waiting for somebody driving 100+ mph. and i will gain acceleration, and that makes me happy ;D ;D ;D ;D
do you have a 0-60mph figure? with what diff fitted?
-
Well top speed is still near as damnit 150mph, so youre not sacrificing too much! Its just revving fairly high....
Re. 0 - 60mph figure, hold on, ill go time it....

What's keeping you. ;D ;D
-
sorry, had to go put enough petrol in it to make sure i could get to 60, the range has been saying 0 miles for a few days now!
The best 0 - 58mph (limiter in 2nd) i could get was 5.9 seconds, with serious abuse of the clutch and trying to stop the monterous 195/60-15 tyres from spinning.
Bare in mind though that this is with a stripped out rear interior and quite a few engine mods.
-
what kind of mods? could you present the car in the gallery? that is with 4.22 diff, right?
-
yeah 4.22 diff,
-primary multi ram removed with manzle style inlet (2x 90 degree 60mm bends blended into 1x straight 90mm pipe)
-enlarged and smoothed lower divider
- enlarged throttle body and modified/enlarged shorter type main inlet plenum (the top bit with ecotect written on it) with secondary multi-ram valve removed with blanking plate,
-egr delete
-4 bar fuel pressure regulator
-ignition advance chip (from germany)
there is a pic of the car from the outside somewhere on the forum (its in my "hello" post) if anyones that interest!
Will try and blag the missus' camera to get a couple of pictures of the engine bay up

this is on 4.22??
is you car go up to 7K rev??
mine on 4.22 was go 55mph on 255/35/18
-
oh, i've seen the your car...it looks nice...lowered, snowflakes, dark blue...nice...
so, you removed multiram...i presume that you have lost the low revs torque? is your EML light on?
shorter type plenum->do you mean the pre-98 plenum? what do you gain with that?
what do you mean by erg delete?
-
close, its black :D
Yeah car revs to just under 7k, dunno why yours only does 55mph on such big wheels, what revs is that at?
no loss of torque low down, its improved with all the other mods. When completely standard the car was gutless below 3500rpm, now its one strong wave of torque from 2k rpm,
Will try and get some videos on youtube with a link of some standing starts.
EGR = exhaust gas recirculation, basically a blanking plate on the hole where it goes inot inley, and a 15mm blanking plumbing compression fitting on the pipe off the exhaust manifold.
on multi ram removal and EGR i left the small control valves conected to stop EML coming on, and just cable tied them out of the way.
I used the shorter inlet because it doesnt have the 'bottle neck' where the throttle bodies on like the longer one does, plus it made cutting the top off and making it bigger, easier.

mine is 3.2 and is DBW where go up to 6700 meybe 6750rev.
my mate after fit 3.0 cams to his 2.5 got rev limiter at 7rpm. before was 6.7rpm
I go to swap flywheel for solid and is lighted from 15kg to 9 ;) will see if this make any differents
-
Are you still using an r28 gearbox?
Courtenay sport do a flywheel that is 5.9 kilo's ;)

**Thread Revival**
Sooo... Will a 4.22 diff bolt straight onto my V-Reg 3.0 MV6 Manual?! Seem like a fairly logical mod to do!
-
I'm thinking that too!
-
Is 4.22 the lowest standard diff ratio available ?
-
Is 4.22 the lowest standard diff ratio available ?
Yes. :y
-
Whats the diff in the ex-cop cars then?
-

Bugger !
Needed a lower one
-
WooHoo!! Well, while the engine's out... It'd be rude not to ;-)
-
Hmm... Can't seem to find whether this 4.22 diff is from a Petrol or Diesel... Anyone in the know available to enlighten us?!
-

most of them have 3.9
-

2.2 auto pertol
2.5 v6 auto from Wreg

and the 2.6 autos :y
-
So i need a 3.70 diff then! lol... Can i still fit the slipper to the 3.70 diff as i have fitted now?
-
How can you identify what diff you have? Do you have to take the casing off?
-

Most of the TVP 3.2 Manuals Ive come across had LSD with the standard ratio Paul, so from memory 2600rpm gives 70mph in 5th, next diff ratio up would give 3000 rpm at 70mph in top IIRC.
Edit, above assumes you still have the calibrated speedo fitted and are running standard 16s.
-
What do you class as the 'standard ratio' Chris?

3.7 would have been standard for a 3.0 manual. 3.9 for auto. 3.2 never had a retail manual, of course. I had a feeling most plod LSDs were 3.9, giving a bit more poke at low speeds for the manuals.
However, the best way to decide what you want is to have a look here: http://www.omegaowners.com/forum/index.php?topic=90497.0 (http://www.omegaowners.com/forum/index.php?topic=90497.0)
-

As Kevin says above, 3.7 Manual, 3.9 Auto, pretty much all the Plods Ive played with had LSD with standard diff ratios including, Met Police Traffic, SO16, TVP, Manchester, Merseyside, Wiltshire etc, the only exception I found was South Wales Police, an Unmarked Swansea MV6 Manual was fitted with a 3.9.
Fairly sure your 3.2 will be 3.7 LSD, although yours is an Estate Paul, so they may have fiddled with it, as said take it for a spin, in 4th a 3.7 at 3000rpm will show 60mph on the Calibrated speedo with standard 16s fitted.
-
are all the diff casings the same size ? ie. 3.7 3.9 4.2 etc
if so, could the CWP set from a 4.2 be fitted to a LSD ?

Watching this space ^^^ :)

Yes, in principle you could swap the CW&Ps over, but getting the mesh and backlash correct once it's installed in the case is not a simple task, requiring special tools and some experience.
-
^^^^
I have someone who can swap these over, just need an ultra low ratio and LSD
I will investigate further now
thanks
