As far back as I could remember I always wanted Vauxhall to make a "sports" diesel Omega, they never did though.
I thought, right I'll get an MV6 then get a 2.5TD (cheap) and drop the engine in the MV6 and have all the MV6 spec with a stick shift, the Irmscher body and wheels etc.....
Well now I have an MV6 I want to do it (might have something to do with free diesel at work ;))
I know I'm taking alot on but when you think about it, it's not going to be that hard. I'll get a whole 2.5TD so I can have the tank fuel lines etc and will take all the other conversion parts....
I recon maybe 1 day to swap engines (match the TD lump to my clutch and box) then 1 day scratching my head wondering what I've done - LOL
The main thing that I think will get in the way is the wiring (fly by on the TD), does anyone have any ideas that might make it slightly easier to do? Bearing in mind I'll have a whole car to take from.

It might be easier to keep the diesel engine and swap all the trim over from the MV6

Thanks.
I did think of this BUT whats the chance of me finding a black 99-t reg saloon cheap? (none)
It would need to be a decent spec also to have xenons and the full mid screen.
The thought does keep crossing my mind though!
-
Does anyone know how I could go about the cabin loom? I am assuming they were all the same?
-
Sounds horrid and wrong, I think moving bits off a scrap MV6 to a TD is a lot less evil

It is possible....
I'd buy a TD and transfer MV6 parts to it....
Your going to have lots of issues with electric!
The diesel is drive by wire for one, so thats going to cause issues as well as a mountain of others, air con system, exhaust...
Just buy a TD and MV6 it up!
-
or stick with the MV6, and sod the TD bit ;D
The BMW engine loom varies quite a lot depending on year.
-
If you are going down the Diesel route with the MV6 you may be better off looking at other engines rather than the 2.5TD.

OH!? Please, tell me more :y
The wiring is the only thing putting me off, as you know it's fly wire....
I want to keep the xenon's and the GID too, thats why (or partly) I'd rather chuck the TD in the MV6 than visa versa.

LOL ;D Makes me laugh.... I've only ever had good experiences with the 2.5TD and I've had 4!!!

Still reckon its easier other way.
The engine varies with year, eg later ones having MAF, earlier didn't. I have a spare earlier loom here. Presumably, your loom will be with the donor card anyway?

Does the Omega loom seperate by plugs behind the dash? If so, would it be a case of matching up?
Thinking about it, what difference is there in the cabin loom between the petrol and diesel?

There must be some difference due to the DBW stuff. I suspect it is a different loom entirely.
Actually, thinking about it, how the hell do the engine ECU get the throttle position - as you may have read, I have just done an engine swap. The engine loom is self contained, and is not connected anywhere else...

Well this is what I thought, maybe it is completely different or MAYBE it just has the throttle switch wires running separately - cant see VX making an entire loon different for the sake of the BMW lump?

I can...
still cant see where tps is connected to ecu :-/

See THe Boys Tractor project, also you do read stories about the 2.5TD lunching itself, also a big difference in performance between the lumps, personally if I was going to this trouble I'd either put MV6 bits on the TD or look at scrappies for a larger capacity or more up to date similar physical size lump - perhaps the replacement for the 2.5 TD with 24valve head.
I just think it will be almost as much work as the RATs Omega going the way you want to.
I think virtually everything under the bonnet will need to change as well as the pedals.
Good luck though

I don't know about the Omega, but a few years ago I was driving a Ford Escort 1.8 Diesel which was a company car. The vehicles were poorly maintained, and sure enough one night while driving I heard a bang and even before I left the driver's seat I know it was the cam belt. The car was towed to a local garage (after it was first towed away to the car pound by the traffic wardens, they don't take notice of 'broken down' signs on the windscreen... but that's another story and anyway I got the fine money back! eventually...) and the engine was declared dead beyond economic repair. Problem was that second-hand 1.8 Ford Diesel engines were in great demand and short supply at the time, while 1.6 Petrol were cheap and plenty... so on the garage's (ill-)advice the company decided to replace the Diesel engine with a used Petrol one.
And this is where things started to go wrong... the 1.6 Petrol engine sourced was second-hand and what is known as 'short engine' so all the ancillaries needed to be sourced separately, then the fuel pump, fuel tank, and fuel lines needed changing, and for some reason the new engine fouled the suspension so some modification was needed there as well (and following that, the car was, as Ralf Nader would put it, 'unsafe at any speed'...). The result was that the piecemeal process ended up costing much more than the car was worth.
The lesson is that there is always more than meets the eye with these type of projects....

markjay: I hear you mate, unlucky! :(
I have just been speaking to a mate who thinks it is completely doable.
The engine loom is fully self contained bar the tps - still looking in to this.
STUFF THAT NEEDS SWAPPING
Engine loom and ecu inc pump and ancillaries etc...
Relay box in engine compartment?
Rad fan and pipe work
Tank with in tank pump
Diesel lines
Exhaust
Transponder chip and pick up sensor
Clocks
Tech 2 session to enable the GID to display correctly.

markjay: I hear you mate, unlucky! :( ...
Not me, the unlucky one was the proprietor who picked up the bill. But as he never maintained the company cars properly in the first place it was only expected. I stopped driving them and bought my first Omega in 1997 when the 'exec' Granada Scorpio I was given instead of the Escort had the rear disc disintigrate from the hub due to rust. Lovely car that is was, 2.9L and all, I prefer to stay alive...
