FORGET IT!

Not worth messing around with.  If you want a faster Omega, buy a faster Omega.

They come no quicker than 3.2 V6, in Black obviously. 

Is the 3.2 Faster than an MV6???

Its faster than the 2.6 MV6, but slower than the 3.0 MV6. Its exactly the same speed as the 3.2 MV6, obviously.

Webby, I've owned a 3.0l and a 2.5 with G cams and a Superchip performance chip at the same time.  I don't give a rats arse what the claims are, the 2.5 is absolutely nowhere near the 3.0l in performance and drivability stakes. And because I had to rag the nads off it everywhere, no more economical. Well, until I killed it

i would say before you start wasting money on chip or remap , get 4.22 diff that will make more difference and only cost about 50 notes

Lowers the gearing to increase acceleration. There are different Omega differentials available

4.22 diff from a 2.6.

Lowers the gearing for acceleration and reaches top speed quicker. However it also raises the engine speed at cruising speed by about 400rpm.... Which doesn't sound much but could grate the nerves a little for some on a long journey.

My 2.6 which is Black by the way does seem to getup and go quick enough

[Phil]

Not wanting to get into a big row about the subject,but I have a 3.2 with a remap showing as some would question an optimistic rolling road read out at 241 BHP......BUT!! having it done with a reputable company and certainly not the cheapo Egay diy crap from Eastern Europe

And yet my old 3ltr MV6 with its £40 ebay chip produced 247bhp on a rolling road. It was in Total Vauxhall at the time, however I don't think it was right

It did have improved fuel economy and did approx 50k with no issues, so i would say, in this case with the n/a V6, you are better off saving money and buying a cheap ebay chip

*edited to add*

It was Polar Sea Blue metalic so nearly black, hence why it was so powerful

Awesome input guys. Thanks.

Apologies i've not added to this recently but been more concerned with the coolant leak i created lol touch wood thats sorted now and if it is then i think ill speak to superchips.

phil, i've watched a ''mythbuster'' video on those cheap egay ones and it showed the one they brought for testing did nothing. not saying thats the case for all obviously. but certainly some out there are dodgy and, having brought some rubbish from egay of late, i think id rather spend the extra and know its a good un from reputable comp.

not arguing, just my opinion

Fair play mate. but i'm just looking to get the best out of the 2.5 with no flat spots. if that was the case id be really pleased with it

And is that an easy job to do?

Wouldn't say easy, but well do-able with the rear of the car lifted.

Check your ratio first though, yours being a 1994 2.5 will probably follow the 3.0 ratios, 3.7 for Manual and 3.9 for Auto, they changed the 2.5 around 1998 from memory.

if Manual with 3.7 I personally wouldn't recommend fitting a 4.22 to it.

Why be that sir?
