I assume it's been done but has anyone got info on fitting GM V8 to an Omega B, have a 2.0 auto so would the box fit? Axle ratios etc etc..... :)
-
Why would you want to spend ££££££££££££ on a car worth a few hundred £s :-?
-
whereabouts are you ? - want me to cruise past in the Holden ? - it's basically the same car.
fitting a V8 is likely to give you problems with steering box clearance mostly - the Aussies fixed this by moving to a steering rack.
and then there's all the other stuff required to make it safe :-
a PROPER brake package, gearbox, diff and suspension improvements.
Budget on £4K for an engine/box combination and about the same for the rest.
and no, there are no V8s that would fit to the current auto box, but then again I can't for the life of me understand why you'd want to keep an auto anyway ?

A good friend of mine fitted a ROVER 4.6 V8 into his, but spent £3k getting the brakes, suspension, gearbox etc to fit/run/work properly, and then was gobsmacked when his insurance company told him how much they wanted (plus an engineers report) to insure it. Good effort/idea/proposal, but extremely expensive for little real gain. what about doing something good with your 2.0 like TURBO or supercharge??
done properly, the insurance companies are better moved to insure it than what they consider is a "non standard" engine swap, however good/proffessional it is.
My buddy was quoted £1500 for fully comp on his, and he's 52 and has a clean licence, and he's a motor engineer by trade!!

elite pete... why do any of us spend money on cars? 'caues they give us pleasure and it's called a hobby!!
woody....cheers, i have full access to proffesional workshop equipment and help but does seem an awefull lot of work, so will leave it well alone.
There was a chap on ebay selling a MK1 Carlton/Holden estate with a factory fitted V8 that needed little work and got no bids and was only £350, trouble is it was on the Isle of White. that's what gave the idea......

You can float it across from the Isle of Wight ;)

Your 2 litre box isn't going to withstand what a V8 can output.
As far as fitting a V8 goes, South African MIG's have the Corvette 350 cubic inch (that's 5.7 litre in old money) lump as standard.

i have actually fitted a 5.7 v8 to my y reg 2.6 mv6, it had a six speed gearbox, think the engine was from a monaro, i know its definitley an LS1 engine and it does go some, had a few confused faces as i blapsed past a couple of sub's, what a great feeling, shes a sleeper to, no new body kit, just lowered with vented and grooved discs at the front and grooved at the back, found myself right up the arss of an rs6 the other week too :) i think he thought his car was faulty, maybe he took it back the next day and asked for a refund

...................just the sort of thing that makes it all worth while - I think I'd have been a bit confused if I was in the RS6!
How difficult was it to put in and did you have to go to a steering rack (like the aussies?)
Any pics of the car?
Yum, Yum 8-) 8-) ::)

i've never done a V8 into an Omega, but i'm sure there would be ways to skirt round the steering box, i would have thought it was the drivers side headers(exhaust manifolds) that would foul the box, although i've never looked tbh as, now, this will get me shot lol, i don't find the omega a worthwhile project, but only by it being 'too modern' for my appeal.
now, give me a nice opel monza and we'll talk lol, but it would have to be something a little bigger than a 350 chevy, something like a 454 big block would be better :)

would you like one ?
I have a GSE without engine/box that could be yours for peanuts

It's a tightish fit.
This is a GTO fitted into a 2004 Catera.

Havent read it, just looked at the pics, early on in the thread you will see the headers, interesting how they have indentations in them to fit the engine in place.

This is how we would all like ours to look.

there are full specs for 5.7 V8 being fitted, as GM almost produced it, but pulled out at last minute, apparently due to cooling issues :( :-/

I bet you have a large grin on your face every time you hit the loud pedal ;D
A mate of mine had a 5.7 Commodore with supercharger and engine work by Monkfish. I;ve never seen the distance get so close so quick, it made his Lotus Carlton look like a 1.8.
Some more picks would be nice

yes mate everytime, but my wallet starts to feel my sudden power urges and beings as i'm a tad stingey a little tear comes to my eye when i look at the fuel gage :'(

fuel gauge, hmmmmmm.
My Commodore is actually quite a bit more economical than either my 3.0s of my 2.6.
my 2.6 struggles to get above 28mpg in normal use, whilst the Commodore has been over 30mpg on every time I've measured it.
last week I did home (Northumberland) to Bristol on the M5 and back again avoiding mortorways, including a cross-Wales blast. 30.5mpg for the trip.

Cooling issues was the reason GM did not put V8 into production :'(

I cant remember where I read it, so unfortunately I cant cite my source, but as I recall, "there were minor issues which may have been problematic at full throttle for long periods of time on Autobhans".
Minor issues which *may* have been problematic..... Unfortunately, I think this was just an excuse. I'm not sure the V8 would have been a successful seller in Europe, and definitely not in the UK. Just look at the VXR8. Such a shame our fuel costs are as extreme. :'(

Police forces would have bought them by the truck load, but guess that was not enough :(

I don't know so much. They have gone over almost exclusively to tractors here - mostly BMW or Volvo. Makes me think they were happy to sacrifice some of the V6 performance to appease the beancounters so I'm not sure they would have gone for V8s on a large scale. :-/

There are enough plod Scoobies and Evos on the road to suggest that they could have justified some V8 saloons.

I suspect GM's price would be significantly cheaper than what plod pay now for the 530d's until the Omega was cut, most forces used them. But i guess they must save quite a few quid on their fuel bills
-
just as an aside i was parked in a shopping precint bloke came up and said "My these are grand cars ive just retired from police force on traffic duty and the new volvos arnt a patch on these , the running costs of the volvo is far higher than the Omega " and went on to say if GM had not said they were discontinueing the Omega it would still be in use to this day

I'm sure there was a similar story with the Lotus Carlton/Omega, It would overheat if driven full throttle for a certain period of time..... then a development engineer pointed out that it would be impossible to run the car for that period unless the roads had been closed and all traffic removed ;D

Is it possible to record a video with this beauty? :) I would watch it everyday before sleep and set it on alarm clock, so I would be woken up by sound of V8... :)

The British Police Forces really had their moneys worth out of GM. The Omega being a replacement for the Senny and Carlton was down to Senny sales being 50% real market, 25% GM Management & 25% British Police! I seem to recall the cops getting Sennys for about £8k.
