A few mv6 questions
30. Sep 2007 at 02:48

Hi everyone I am new o this site and a new omega owner, I had a vectra before and now I wanted an omega, I have a few questions, I Have just got myself an omega, its registered on the logbook as 2.5 but im sure it has an mv6 engine can some one tell me the obvious differences please, Anyway i think i have a 3.0 v6 24v rear wheel drive manual, not sure if this is common? i have been reading on this forum about people having lsd how do I know if I already have one seeing as this has had an engine change.

Now lastly he engine seems quite sluggish up intill 4500 revs and then it really kicks off is this normall or is there somthimg I can check.

I would really appriecate your help.

hello i also have a 3.0 mv6 and i bought a chip from ebay ( germany) and it has this effect at 4500 rpm so if you have a 3.0 engine fitted it may have the same chip fitted as for which engine you have i think it is no big difference to the untrained eye but i am sure some omega expert will be along soon to help you check which you have , HTH

There is no MV6 engine as such, the MV6 had lowered and stiffened sports suspension plus some other minor differences e.g. sports seats, but the engine is identical to a non-MV6 car (e.g. CD, CDX, Elite).

The engine may have been chipped but this is not directly related to it's being MV6 or not.

Also, many MV6 were in use by the police, so could have some other improvements such as potentially higher rev limiter etc by the police force in question, but again these are not standard fitments on MV6 cars.

And as said by AA above, the MV6 was never available with the 2.5L engine, initially only with the 3.0L and later also the 2.6L and 3.2L.

Sep 2007 at 10:13 Not easy to tell the 2.5 and 3.0 apart. If its post 1998, the 3.0l will have a longer plenum. If you post up the MID codes (press and hold S and R together for 3s) I can tell you what that is programmed for, but obviously if the MID or engine has been changed, that could be wrong.
