Title: Vectra B V6 Plenums.............
Post by: pedroMV6 on 14 February 2010, 19:49:04
................ inlet tracts and cam covers.

Anyone know if they will fit in the Omega engine bay (OK, so I know the cam covers will), and if so, can anyone tell me why they were only fitted to Vectra B's?

Got a feeling that the longer inlet tracts would aid the torque output.

The real point was they could not fit the SUPERIOR multiram in the space in a Vectra, thus Vectra's have the more compromised system.

But doesn't the Vectra have a multi-ram system? :-/

Is it though? I thought the Vectra B V6 engine had a multi ram system..........

It does but, its a more compromised setup to fit the smaller front wheel drive engine bay

Still compromised on VectraC? 3.2's of those are plentiful and cheap!

Trouble is the early ones are bl000dy ugly, the facelifted ones look loads better from the front.  But still not keen on those interiors. But for the money, can't complain  :-/

Soooo cheap, low miles!  :o

But FWD then, and butt ugly  :(

Whoa whoa whoa sweet child o'mine.............
Going a little off topic!

I kinda thought the Vectra B V6 inlet system would give a little more torque  - and look rather nice - when bolted into my 2.5 Omega.

nah, current setup is best. Metal cam covers not a good idea either, cam covers won't blow, granted. But will cause more serious issues like crank seal.

Hummm cam cover or crank seal, tough one  ;D

But will the Vectra set up fit under the Omega bonnet?

I think it would, but prefer someone with the experience to verify.

Or not!

Need the ECU as well due to the multirams.

Also AFAIR the WWD engine also has only a single throttle body

Good point, Martin!

Just that a 2.5 V6 Vectra B with alot of rust (MOT fail) is available near me................

That would do you :http://cgi.ebay.co.uk/2006-06-VAUXHALL-VECTRA-SPECIAL-VXR-ESTATE-V6-2-8T-FSH_W0QQitemZ140383306225QQcmdZViewItemQQptZAutomobiles_UK?hash=item20af7f41f1

Better engine 6 speed manual, trim pieces it needs are very easy to come by too.

Anyway on topic: Crank seal issues the veccy cam covers cause.

may be a little offtopic - is there any description about Omegas multiRAM system? variable intake length system, which is used on Vectras is described in Vauxhall College pdf circulating internet.

Of course, its not hugely different.

What it compromises is the low down torque so wont affect high rev activity.

Which, particularly in the case of 3.2 Vectra-C, due to its bloody awful chassis, is no bad thing, as it then stands some small chance of getting around the roundabouts of Milton Keynes without using the kerbs ::)
