Why are people not getting rid of that V6 and chucking in the Saab 4pot?
Much higher BHP, shed loads more torque and as the Omega was available with a poxy 4 pot, surely it cant be that hard?
Why bother with a very costly V8 tansplant (except for sound) when an I4 will do the same?
Discuss.

Loom issues?
-
Loom isn't an issue, there is an adaptor available. Granted some may need to be extended. 2.0 engine is the easiest conversion, although on the Vectra I believe they use the 2.0L non-ac engine mount. Not sure what you'd do with the Omega.

I love the sound of a bigger v6 and the effortless pull, I've had plenty of turbo cars and they just don't give me the same smiles per gallon as a big 3.2 v6 does, not everyones cup of tea i'm sure but I'm happy to pay the extra cost of fuel for the satisfaction of the drive :y
-
What I love about my V6 is that she's never trying. There's a steep hill immediately as you come off a roundabout in a nearby town to me. Come off, accelerated uphill, I swear the engine never went above 3-3,500rpm, smooth, engine note barely audible, just a big engine, unstressed, doing what it's meant to, as opposed to a smaller engine, forced induction, revving higher.
In no way knocking the engine, and one in an Omega would be a hoot, I personally think it was a wasted opportunity, and there should have been an Omega Turbo, but Saab's unit would have probably better suited in a Vectra, Astra, something lighter.

You've not driven a full boost Saab then ???

Nope. Would like to, though, definitely. :)
As a sort of clarification to what I meant, for any of the V6 Omegas, if you're looking for a fast-revving, nippy, tyre-screeching experience with loads of torque and a powerslide just a blip of the throttle away, then you won't get it. They were never designed for that, in fact the entire concept of the engine was smoothness and (relative) economy. As also proven, they don't take too kindly to forced induction, not without serious bottom end modification. A serene, quiet ride on the motorway is what they were made for, and is exactly what they provide in spades.
Punchier, tougher old boots like the 2.0 GTE engine and 2.0 Turbos served that role of small but powerful job well. Perhaps a 2.0 litre Omega in the range within a few bhp of the V6 versions may have been seen as a bad sales tactic, who knows?
I know this has centred around the Saab unit - but there's a couple of Turbo Vx engines that were in the Luton 'parts bin' during the Omegas tenure, the Calibra/Cav as mentioned, then the later Astra/VX220 Turbo unit - I'm no expert but are these considered no-go?

Its on the cards for MrsGK and I's next project. ;D

Looking forward to the results! :)

Looking forward to the results! :)
Wont be until next year I think - got two Omegas and two Mercedes to finish first...

Goodness me,thats a big snail :o :o

Mine redlines a little too easily... Trouble is, once you start getting from 3000rpm and beyond, there's no stopping the thing :-X
Fortunately the Monaro brakes don't fade at all, eben with cheap discs/pads... Should probably check the pads though ::)

:-\ The V6, especially the 3.0 isn't really what I'd call smooth, especially not when you nail it. And the economy is really quite poor when measured against a BMW 4.4 V8 of the same era that can do 30mpg. And it really isn't fast by modern standards at all. It would easily get battered by something as mundane as a C220 CDI from a standing start. Gearing doesn't suit (slightly illegal) cruising speeds either.
Not to say I don't like it as an engine I must stress.

Any number of reasons:
first, you're advocating an engine swap when there are people who resist buying anything other than Vx oil and filters?
second, the V6 Omega is a well judged combination; a 3.0l has enough power to spare so that loading it heavily doesn't make much difference to the performance, plus it's quiet, smooth and (relatively) economical
modern engine swaps are a pain to do compared to heaving a small-block into a mk2 Granada(I've a mate who used to do those in a day)
I doubt there are that many of us here who are actually interested in that sort of hot-rodding

A V6 by pure definition is smooth, no exception with the X25XE, Y26SE, X30XE, Y32SE. A properly running Vx V6 is like silk.
Same era V8 BMW stands no chance in the 'economy' department. My e39 535i would struggle to get above mid teens, and the 339 is lighter than the Omega by a fair amount.... step up to the 7 series, and it's laughable. Ask me how I know!
Comparing a 20 year old car to a modern diesel is like comparing a Mother to her Daughter - Miles tend to wear out Humans, much like Cars. Ask Lord Opti how he knows.
Anyway - On that last point, a standard B234/5R with TD04 (all standard) in an Omega would make a modern 530D shit itself..... after a remap, and it's bye byye!

First: What's that got to do with anything? I've asked on a forum a question - Just because someone will only ever use Vx Filters, why wouldn't they use another engine which uses the very same Vx filters? :)
Second: Nope, except for the smoothness - which in part is throttle derived. I could make Hamilton puke in an Omega.
Third: Why? GM derived, practically plug-and-play, I'd wager far easier than replacing a V6 in a MkII Granada with a asthmatic V8.
Fouth: Each to their own - It's not hot-rodding. Hot-rodding is sticking an asthmatic engine into a 3tonne Ford! ;)

Nah, It's the raspy rugged soundtrack to the first 4 series of road wars. Nothing refined about it.
My 740i averages 29.8 ;)
Well obviously... but a select few on here genuinely seem to believe their standard Omega is "fast" in 2015. It isn't.
If you remapped the 530d it wouldn't. (other than the fact the bm is so unreliable it'll blow a main bearing or coke up it's intake valves and thus may lose due to being stationary) ;D

Are you driving it or towing it? ;D
A remapped B234/5 9000/9-5 will leave a remapped E61/E90 530d for dead. And bear in mind that a remap for these engines is roughly £70 from a well respected Guru. With around 1k of work, it'll keep an E60 M5 on it's toes..... That's a lot of bang for your buck!
-
The former. Not particularly sedately :P
"yeah but if I added afterburners then..." ...Besides, real men would have the 535d XFR ;D
