Advice on this diesel engine conversion please
« on: 18 August 2007, 17:03:58 »

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!

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.

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?
