Read on the parkers website that the 2.2 is alot slower but the stats are only half a second slower 0-60.

is it the torque thats alot lower then? , if so if i had it tuned up it should at least match the 2.5 on pulling power then and be a bit better on fuel.

Any help appreciated.

People ask questions like this all the time. My question is: If you buy a diesel you are surely more interested in economy than performance, and, if you race your tractor, you'll lose economy. So..why?

[omegalord]

Well,

I arent after a diesel especially for the economy. I am after something that doesnt have all the problems a v6 has (rocker gaskets, hbv, overheating etc etc) but has a bit of poke to it. I want a good compromise in performance and economy/smoothness. I have no intention in racing a diesel but i dont want to have a car that pulls like a 950cc fiesta either.

Hmmmm.......hows about a 2.0/2.2 four pot then?

[omegalord]

Why would i want a 2.0 or 2.2 4 pot when they obviously have little torque low down acompared to a turbo diesel?

Yes, I suppose so. I have owned a 2.0 and a 2.5 and, to be honest, in everyday driving, there wasn't that much to choose between them. It's a matter of personal preference I guess.

I have a 2.2 auto and it struggles to keep up with things like Mondeo TDCI and Passat TDI's AND only averages 25mpg daily running!!  The 4 pot petrol IMHO is very underpowered and struggles to pull the heavy Omega body, plus the 4 pot is harsh when driven hard and rough when cold.  Shame as I love the shape/style of the Omega but I went for the 2.2 4 pot as I didn't want the complexity/unreliability of the V6!

Thats exactly why i want a diesel. Never have i had a petrol car that has so many niggley problems. Thats why i wanted a turbo diesel as it will have alot of good low down torque which will make it a pleasure to drive. And as i dont intend on racing or doing 140mph everyday then the horsepower loss of a diesel wont affect me.


Any opinions on the original question over the 2.2 or 2.5?

It's hard to find the information you're looking for Matt. I can only find the 0-60 times (11 and 11.5) top speeds and the like. I guess the ideal person would someone who had owned both. There must be a couple on here, somewhere.

[omegalord]

Yeah. Dont get me wrong i would be happy with both of em , but if the 2.2 tuned a bit would be as good through the whole rev range as the 2.5 and return better mpg then i would go with the 2.2

Also it would be a vauxhall engine and i like vauxhalls.

Yeah , seen that and a few others. It seems the 2.2 isnt that far behind the 2.5 in torque terms. The hp is better in the 2.5 but i aint planning on going above 70 anyway.

I have the 2.2dti, I have had diesel cars for a good number of years and like the torque they provide, yes the roar of a V6 is nice too, I did have one,I also had a V8 range Rover  

All have pro's and con's.

I will be able to report back on the tuning off the 2.2dti as M-Tek is doing mine next week  

There is the option of 2 maps, 1 for economy and 1 for power, my head says, economy but my heart says power..............M-Tek you listening....I'm going with my heart  

Will let you all know off the outcome.

[omegalord]

Cheers alan,

What is the 2.2dti like for the omega as standard. Does it feel sluggish or does the turbo give good torque low down?

Matt

As an example, the road service have recently re-surfaced a road just outside work and it had been finished with that very fine gravel, at 20mph in 3rd I can floor it and spin the rear wheels all the way upto 50mph   good fun (well I am putting new boots on Saturday) a mate at work tried it with his Passat Tdi (130) but can only get his wheels to spin in first (yeah I know front wheel drive, weight etc)

The torque is best in second and third, you really feel it even if it is only for a short time  

I understand that after M-Tek has had a play with it, it will be the right side of 150bhp and torque upto about 330! with a slight increase in the mpg
