Have the plug leads been taken off during engine swap? or maybe the flow and return fuel lines are mixed up?

Omega General Help / Re: will an mv6 lsd fit straight into a td
« on: 09 September 2010, 17:27:39 »
i would agree with lincs_robert, not all mv6's had lsd fitted, it was only an option (the 3 mv's ive owned have had open diff's)
And there is no way of visually telling if it is or not from the outside, the only way is to take the back plate off a physically look inside.
Mv'6 have a 3.70 ratio diff, the diesel is 3.45
If you fitted it, you would have much shorter gearing, but not un-driveable.

Are you still using an r28 gearbox?

close, its black 
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.

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

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.

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....

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!
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

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

It depends on the size of the wheels/tyres as well, bigger wheels = higher speed.

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

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.

Omega General Help / Diesel vs Petrol Bell-housing
« on: 09 September 2010, 18:02:02 »
Hi, just a quick one, does anyone know if the bell housing for the 2.5 td bmw engine is the same as the X30XE?
If not, is the 2.2 Diesel the same?
Thanks

Omega General Help / Re: Engine swap Straight 4 to V8
« on: 08 July 2010, 22:19:54 »
other problems you'll come across are:
Not enough room with the standard steering box, will have to be converted to rack (like what can be seen in the link above)
And one of the biggest ball aches is exhaust manifolds, just have a look how tight it is on the near side between engine and chassis leg on standard V6, now try and imagine trying to squeeze some sort of 4 branch manifold in there.
Me and a mate tried offering a 5.7 cleveland V8 into a bare omega shell and its suprising just how tight it is in there, for such a big bay, even with battery tray and loads of other bits cut out, it was still impossible to get the engine to sit right without major modifications, so ended up scrapping the idea.
3 litre, straight 6, turbo toyota supra engine would be a far better idea
