hi every one , after info on omega estate , the 2.5 d is rear wheel drive but is the 2.2 d rear or front, going to be towing a twin axle caravan so i need rear wheel drive and the weight and bhp, the 2.5 is 140 and the 2.2 is 120, not alot in it or is there. any advice chaps. many thanks. mosty3

All Omegas are rear wheel drive.

The 2.5 is a de-tuned BMW 6-cylinder diesel.  When fitted in a BMW 525tds it produces 170bhp, and this can be achieved in an Omega by chipping the ECU (details on this forum)
The 2.2 is a 4 cylinder Gm engine, and as you say, produces 125bhp.

The 2.5 was fitted to Omegas from 1994 to 2001, it was then replaced by the 2.2 until the end of Omega production.

Personally I would say you'd be better off with the 2.5 if you're towing a heavy caravan, but the choice is yours.

many thanks for the info. cheers mosty3

Also, 2.5 6 cylinder is available with an auto box, the 2.2 is only available with a third pedal and having towed miles with my auto wouldn't want the hassle of a clutch when towing. 

But that's up to you.

I like my 2.2 but for towing a heavy van I suspect the 2.5 is the better option.
As stated 2.2 was never offered with auto (AFAIK), I often wondered if this is because the engine is already marginal for the car without losing horses to an auto?

Reports on OOF suggest the 2.5 auto is not all that economical - but doubtless will be nicer for towing.

IMHO??? BMW lump 2.5 all day long

Lol, although the 2.2 certainly seems to be a bit more reliable.

I'd opt for the 2.5 for smoothness and torque. Both of which are important when towing.

Although the 2.5TD are old hats now, my choice would be 2.5 with manual.

Twiglet I was thinking the 2.5 v6 petrol has 170 bhp not the 2.5 td diesel

2.5 diesel has 133 bhp the 2.2 dti has 120 bhp

I think.

He was trying to say that you could get 170bhp if you chipped a 2.5td.
As others have said get a 2.5td manual and chip it

That's funny, we have plenty of 2,2 with auto box... and if I'm not completely wrong it's the AR25 box so should be doable to change manual to auto

Petrol or diesel? 

[kcl]

Sorry, my bad... gasoline ones. No 2,2 disiesals AFAIK here, only 2,5 ones

2.5 diesel can be chipped to 170 bhp in full BMW spec, manual is best for this. If you chip an auto the gearbox will have to be upgraded to the AR35 fitted to 3.0 & 3.2s as the standard box won't handle the torque.
