Is the bmw straight 6 lump 2.5td (the one fitted to omegas) similar in build as the petrol version if so would it be possible to fit an m3 or 328i engine in the omega using the diesel engine mounts?  This issue gives me sleepless nights. I would love to fit a 320hp motor in my omega.

It would be easier to fit Lotus Carlton running gear,although finding it might be the hardest part.

Has anyone ever put a straight 6 in an omega ? Cant recall seeing one

Vauxhall put the straight six TD lump in there so every reason to think that another straight six petrol or diesel would fit

As above, every 2.5 TD is a straight 6 

Also seen a Lotus 3.6 S6 in an Omega, which went in ok.

Think a 328i engine would be pointless, as would 3.0 straight 6, not much gain?

The Lotus 3.6 is hard to find and would be expensive to run also its turbo so I'm guessing they are not cheap to replace.
M3 3.2 (e36 version) 320hp or (e46) 340hp I think is a good enough option. The 3.0 (in the e46) has about 245hp and I think with a little tune would run about 260, me thinks anyway    So it does seem worth it. I know the omega v6 can get some serious power, but I'm not sure about reliability. 

Unless you guys can tell me if you can swap in like a 3 liter diesel from the 5 series ?

If I can squeeze a 3.8S Jag lump and gearbox into a 105E Ford Anglia, then anythings possible with engine swaps   Having said that some transplants are easier than others, and other parts usually need upgrading like suspension, braking and drivetrain etc

Tbh if I was doing a swap I would buy a whole car so I could get all the bits needed

Apart from no cuts to the hands when working on a V6  I guess the Skyline would be a better transplant option
