I am looking at dropping a 3.0 v6 saab motor into my 2.5, & was wondering if anybody has done a turbo conversion on their omega, & how difficult it would be etc.. Also I presume that it is the same as a x30xe? I hope so! :)
-
It's been discussed before. Problem is the Saab is wrong wheel drive and the omega isn't.

...so long story short, stick a v8 in it instead. There, job done! :)

The Saab has a low pressure turbo so for all the work installing it there's not much difference in BHP. Courtnay did a couple for the Irish Police but they weren't very successful.

Whats the omega internals like compared to the saab's?

What from? As in is there a uk unit available or is it a chevy one from US or something?
Any link to previous discussions?

good luck :) :) :)
catera is more or less omega

Looks like v8 will need a steering rack, or a cooler for the steering box. :-?
-
Fair enough then, has anyone fitted a Rover v8 before, as I work with them anyway.
-
Is it worth fitting a rover v8 over a 3.2 putting out 210 odd bhp? For the cost and effort involved I'd want to see at least 350, with a possible 400 at least.

Still doable though, either way.

...thinking about it, provided the exhaust clears the steering box, an inline cooler would probably be the simplest I guess....?

no point putting the gutless Rover V8 in, you want to fit something like an LS1
-
For me a 300 bhp Rover motor would be a cheaper option than a Chevy motor, but anything over 300 would definitly be a Chevy.
I noticed that the Saab was a Garrett GT15, which is a bit small, would it be possible to fit a t25 or similar?

gutless...? whats that mincy 4 pot put out T ? ;D :P ;D
-
About 250 bhp :P
Wait no thats the torque ;D
-
... torque or talk? ;)
-
A Rover V8 needs quite a lot spending on it to get to 300 BHP. In fact, any one you pick up second hand will need a fair bit spending on it to get it back to a reasonable level of wear before you start tuning. More support for tuning it than the GM V6, but you're starting out with an inferior engine.
A chevy V8 engine on a crate from the US will drop straight in and give a reliable 350BHP all day.

Just a thought about the original issues with saab being front driven, and therefore unsuitable....
V6 Calibras/Cavaliers, both front wheel drive, use a version of the Omega V6 (or should that be Omegas use a rwd version of the Cav's fwd V6?!!?)
At some point the engines are identical, surely. Why cant you take off the 'bit', presumably at bottom end, that's fwd from the saabs V6, and stick on the 'bits' from a rwd omega V6? I know Im being a bit over-simplistic, but nonetheless, they are, as far as i'm aware basically the same engine.
I'm sure I have seen, possibly at Billing, a fwd v6 in something like a Commodore/rekord, maybe even a kadett. The point being, they had altered it to drive the rear wheels. It must be possible, or am I just an optimist with a bad memory? :-X 8-)
-
sodium valves and holes/oil feeds in the rods by the shells (although I now think the mega has sodiums)
I got some saab rods when I was going to rebuild my old 3.0 elite.
Cheaper an equally powerful/torquey option would be the 2.3 saab 4pot. Would work on the standard box too :)
I have looked into all sorts of conversion options on omegas, saabs and nissans combined, including tuning :)

Anything is possible given enough time/cash, plus there is the bangs for buck/effort consideration. Th ls1 makes the most sense, it's narrow, push rod heads although a bit old school are very compact, bulit prrof reliable and with negligible serving needed. No rather about with turbo's to get decent bhp and fit almost anything rwd with loads of tuning and knowledge available.
How much bhp from the Saab turbo engine?

About 250 from the 2.8v6, not sure how closely related it is to the 3.0/3.2 v6 though. :-/

Having said that, if the newer saab boxes are similarly bolted to the engine as the earlier ones then why couldn't an omega box fit the 2.8 as well? :-/
Ls1 is probably most satisfying solution to more grunt. 8-)

:o ;D
i am looking for flat LCD connector for saab 9-5 ACC display
-
Better using the saab 4 pot 2.3 from a 9000 with a tdo4 turbo,225bhp standard and tunable to around 300bhp with a decent flowing exhaust and remap,mates up to the omega 3.0 manual box too.
-
Fair enough then, has anyone fitted a Rover v8 before, as I work with them anyway.
To be blunt, I'd fail to see the point.
Surely getting 250bhp out of the V6 Vauxhall lump would be a lot cheaper than sticking a RV8 in it and trying to get more than 250bhp out of that?
Wouldn't the best option be sticking in one of the supercharged 3.8 V6's out of the Commodore VT or Buick Regal, (both of which are based very heavily on the Omega B anyway)?

...yep, and take the process further. We're knocking on the door of an ls1,2 or 3 etc.
I suppose it's all in the eye of the beholder to an extent, but to me, more power to less maintenance has got to be the way to go IMO.
How long will turbo/4pot last...? And the omega v6 bottom end won't take much more than stock bhp without exploding. In fact it's the reason some v8 omegas where built. Which is a shame as bolting on a super charger to the v6 lump would be easier I'm sure.

wat is the differnce of the saab v6 turbo to the omega ? , are they not the same family of engine surely there cant be more work in getting it into an omega than a rover v8 and its gearbox ?? and the price of an ls1 and box , changing the steering box to rack etc i think it would be cool to have a saab v6 turbo engine in it , different from the norm anyway , and doesent seem to be totally different engine from the original v6 im surprised no one else has done it sooner
-
ok, think it through, where are the turbo(s) and exhuast routing going to go?
Dont get me wrong, if it works on the v6, it might work on the v8 too. ;D ;D
-
the size of the exhaust and turbo are the only things that are stopping such a conversion ? anyone know what the compression ratio is of these saab turbos ? , and what power they give , i still think its easier buy a monaro than getting a v8 and running gear and putting it in an omega cant be that hard to get a saab engine on the cheap and making it fit
-
18 months ago, I came across a bloke who was fitting a turbo'ed rover v8 in an Omega. It was up and running when I saw it (infact, it was the v8 noise that made me wander into the unit next door to see what it was - i had no idea it was an omega!)
Sadly, I've never been back down to ask the bloke what the outcome was. (must check and see if hes still even there!)
He was rebuilding the Omega for the drag strip and had stripped everything off it.
I told him about OOF, and he said 'nah its not going on the internet, I don't even know how to use a computer!' :'( :'(
On my way out I spotted 'something' else sat on the floor looking like it should be under the bonnet of my car... which made me promptly turn round and ask him about it...
his answer was something like 'No, sorry, the LS1 is going in the next Omega I build so not for sale!' :o ::) :P

Or a Commodore even? Cheaper and more about. Plus similar to the Omega, (or same if you pick the 2000-2003 model).

Of course it's easier to buy an Ls1 equiped production car. But this side of, what, 12k? There ain't no toys in there. No remote window and sunroof closing, no heated auto memory seats/mirrors/rear view mirror, rear blind, rain sensing wipers and all the other Elite Omega Stuff. Ok Elite toys aren't for everyone, fair enough. But stick an Ls1 in an elite with proper suspension and brakes and that's what I call cake and eat it time. ESP if the v8 runs on LPG at a later date(if the price per litre comes back down again)
Well that's my thinking...? But I'm all ears if anybody has a better plan. Should add, Elite concerned has Irmscher everything, if you like that sort of thing. 8-)

...and why don't these smileys work. :-?

nothing can replace engine volume, no turbo issues, no cooling problems.. my vote goes to ls series..at least worth the money spend imo.. when playing up with the turbo any mistake done, you will have a bang and all spend and work done evaporizes :-/

If its the 3.0 Saab turbo your looking at then there is only 2 BHP difference, really not worth the trouble
