Title: 2.6 omega spec against vec gsi spec
Post by: so comfortably numb on 09 June 2011, 23:39:00
Wonder if anyone can help.  The 2.6 in the omega is rated the same power as the 2.6 Gsi (or so it would seem) where as the 2.6 SRi vec is lower.  From what I remember when I had my 2.6 Gsi, they had had 3.0 (omega) exhaust cams in to get the higher power over the SRi 2.6. Can anyone confirm or deny this please?
So basicly what I'm asking is (I think) is the power output of a 2.6 omega about 178 or so?

2.6 Omega is in the region of 175bhp (not got exact figure, but approx same as the 2.5 Omega).

The Vectra is lighter, so has better PTW ratio. Also, if the 3.2 GSI Vectra is anything to go by, shorter geared. Though try getting the power down, even in the dry, on a Vectra-C - probably one reason that the Vectra-C GSi's have steel girders instead of suspension ;D

The Omega has the multiram system to smoothen out the power curve, making it less peaky than the Vectras

iirc the 2.5ltr on the book shows 170bhp, so I would guess the 2.6 will be very close or the same.
The main difference between the 2 cars though is the weight!

One is lightweight and the other weighs like a tank.... but I wouldn't have it any other way  :y

"I thought the old veccie GSi 2.5 was re-worked to give 200 bhp"

The vec b gsi pre-face are around 197.  The facelift 2.6 are around 178.  Bigger cc to compensate for the lower compression to get the emissions up, but had more torque than the 2.5 gsi.  The white super touring was 200 bhp.  They have a x30xe map.

It was the original 2.5 gsi that had the uprated cams thanks to msd and was in the region of 195bhp

2.6 did not.
