Title: V8 Omega??
Post by: moleymv6 on 26 March 2007, 17:37:33
Just wondered if anyone knows if a V8 has been put into an omega??

I heard that Opel made a prototype omega, but it never went to production.

I assume the omega shares a similar platform to the holden commodore, so it should fit.

If anyone has anymore info on this, or knows of one in existance, that would be quite helpfull.

Many thanks

I read somewhere it was to do with the engine breaking up at full rev's over extended periods - but you're right, it should be doable in theory - sure someone on here more knowledgable will comment :)

well I've heard two rumours:

1) it never made it into production due to cooling issues, probably as ClarCE suggested
2) it did, but only in LHD ... but this seems unlikely ... I think the Holden cars use a different engine?

There are references to the V8 omega in TIS and EPC though, including an aluminium bonnet ...  ::)

The Omega V8 never made it into production, just a 'one off' concept car, GM couldnt be bothered to spend the money getting it to work properly is basically the reason, and to be honest i dont think in 2000 they would have sold that many.

The V8 works in the Commodore because they take the standard Omega floor pan and make it wider and longer.

To try and dump a V8 in a standard Omega would cost 'possibly' more than buying a '99 VT HSV GTS

Cheaper and more obvious exhange is the Lotus twin turbo engine, and as has been done before, leave the 'steelies' on and its a proper street sleeper  :)

LC would never pass a modern emissions test....

I heard that the German regulations require a production car to pass a test whereby it is run flat out for extended periods on an autobahn (in a similar fashion to the taxi driver who last picked me up from Munich airport - in fog!).

Apparently the Chevy V8 died due to problems with coolant flow which were down to the block casting and they decided it was not worth resolving.

Can't remember where I read the story now. Autobahnstormers maybe?

Rover managed it on the 75, but it was a tall order for GM  :(

Thats possibly because Rover had some bloody good engineers.  Crap management though (esp in BMW era), hence their demise...

The V8 would have been great, I believe it was going to be offered with a 6-speed box too. Even the manual 3.0 always feels like it wants a little more power, and the extra ratio would be very useful too.

I'm surprised no one has done this in the USA other than the John Lingenfelter Catera-V. The junkyards are overflowing with recycled 5.7 liter V8s. Cadillac should have had a V8 option from the start like Lincoln did with the LS. Below are links to pictures of the Catera-V as well as Omegas and Commodores with V8s.

Ultimate - perhaps a race is required between it and OmegaToys old 2.0 GLS with the Lotus straight 6 ;D :y

How about just putting a blower on the 3.0L?

Hello,
I found these picture's on the web of the V8 Omega:

The Engine is a GM Y57XE

If you look at the last photo of the holden V8 the battery and the air filter are the other way round

Wouldn't fancy changing the HBV or cam cover gaskets on it, but nice all the same!

My dream project would be to find a smashed up Monaro VXR 6.0 (rear ended one) .... and transfer the engine, brakes, and gearbox into my 2.2  :D

I'd would then leave all the styling bog factory standard!   :D :D

It can be done but the bottom end isn't strong enough for it to be worthwhile, anything over ~250 BHP isn't likely to be reliable.

John Lingenfelter company bought all the prototype parts from GM, it was about enough parts for 15 cars. Their plans was to convert Cateras to V8 power but it was to costly and the plans was abandoned.

They sold out the parts, if I remember right it was $2000 for a complete kit with frame, brakes and rear end center section, exhaustheaders and a lot more small stuff.

link to the rats omega here. It is in Norwegian but google can translate.

http://www.rats.no/omega_tg.html

1000bhp is the associated head line on you tube or somewhere iirc.

The project was taken on as a show case for the company to advertise its transmission service. Hence big bhp to prove their whole transmission could take the power.
Omega used for slippery shape.(gls i think)
V8 was a battle due to size of the lump and involved cutting the chassis to make room for the back 2 pots, junking the stock stearing linkage as it was in the way, used something off a nissan as more compact i beleive. But very tight fit to avoid bump steer, which was the challenge to get the front to work.

Dif has its own cooler and appears to be the limiting factor in transmitting that amount of hoof.

Project took over a year due to solving issues and sourcing parts, and thats with major facilitess available. Big job.

Also think there is a v8 omega running in a British championship somewhere. A member here i beleive.
