Shoot me down in flames if I'm wrong, but isn't the Saab based on a Vectra floorpan and mechanicals?
I think that's only the 9-3.  The old 9000 only had a few GM bits, like the auto tranny where the o/d would eat through the end of the casing and come out the n/s wheel well.  :-?

To be honest, the Omega is well enough balanced so that the LSD does very litle unless its mega slippy...
And that's when I wouldn't want one!  I don't miss it.

I've run a modified turbo sedan to well over 200K, including track time.  The turbo at least was reliable.   ;)  The question is your price range.  For the price of a cheap Omega, you are not going to get a reliable turbo sedan.  They can be death by a thousand paper cuts more than even a bad Omega.  All of the rubber hoses go brittle due to the higher engine bay temps, manifolds crack, exhaust studs go, and on and on.  However, there are several options;  Sierra, Audi, Volvo, etc.

You can quickly get to the point where it is cheaper and more enjoyable to have two cheap cars instead of one highly modified one.  Do a few things to the Omega, then have another project car more for your individual enjoyment.  Trying to run one highly modified jack-of-all-trades can be very expensive and frustrating.  By the end, I realised that it was cheaper to buy a fancy and fast new car!

On the subject of drilled airboxes, they are the opposite of a cold air intake and usually reduce real world power.  They can give false improvements on the RR if you have the bonnet up or have the fan pointed directly at them.

Everyone has their own opinions.  Induction gains vary from car to car even with the same engine, 12hp is not unusual if the original is a restriction.  However, also easier to lose hp than gain with an induction kit.  Manufacturers' claims are useless.

Cat restriction again depends on car.  Clogged cats are always a problem, however standard cats often aren't a huge loss on non-turbo cars.  I think it is always better to leave the cats in if you can.  Can have unintended consequences with the exhaust note/booming.

FPR can give small a benefit to fuel economy, due to better atomisation, and support gains from cams, etc.  Best if chip/remap is set for new FPR.  Will throw off trip computer.

A big car like an Omega isn't going to see the same benefit from a lightened flywheel as a lighter car.  It also degrades the comfort, especially if replacing dual-mass, which is what an Omega is more about anyway.

In short, the only sure route is to listen to people that have done things to the same car you have, and hopefully have RR results to prove it.

I put on Bilsteins and later did normal springs when one broke.  Easy, simple, pulled the fuse.  Was all fine until I had to get the in-laws from LHR 2 weeks ago.  Sat on its @rse and scraped on the speed bumps in Oxford services.  (No they aren't overweight, 3 in the back and luggage adds up fast though!)

Usually just me or me and the missus in the car, so I don't regret it.  If you have anyone in the back seat with any regularity I'd get self-levellers again though, especially if you plan on keeping the miggy for a few more years.

Hi TB
Question :

Would tech2 when used to test gearbox ecu, provide suffcient power to energise the solonoids. Or does it provide a switching voltage, which it then tracks.

Or

The ignition needs to be on, and or the engine running. Your reply would  save the trawl of the book of lies.
  
AFAIK the ignition needs to be on for all Tech2 type work.

Hi again guys - thanks so much for all the replies.

Confirmed by paperclip test - code 19 = Crank Sensor.

Didn't realise it was such a bugger to get to so will check which type I have over weekend and get her all fixed up early next week. Dealer recommends the square type with the pins all the way up to the shrouding but worth checking one suspects.

Now, to get home from work safely - you're quite right there is no warning at all when she goes, I do consider myself extremely lucky so far!

Thanks again all  :)

PS> How handy is the paperclip test! -Cheers
Dealer gave me the wrong one first time.  PITA.  My advice, take the current sensor out ASAP and get a ride to the stealers.  Keeps you from driving the car, and makes sure that you get the right one!

The other piece of advice is, DON'T drive a car with a bad crank sensor!  Not safe!

Mine gave no warning.  Consider yourself extremely lucky so far.  ;)

Being a Y-reg that car will be subject to the proposed road tax changes.  That will affect the value.

Sammy . . .

. . . but I would jack the arm up slightly first.  The shock is holding tension on the spring.

Can someone please tell me if the levelling servo on facelift model is the same as a pre-facelift model?

Cheers
I've been told that they are not.

Yup, file a 45 degree angle on leading edge :y

They were filed........or machine cut by the looks of it......on leading and trailing edges.........or do they need more of a file  :-/
Have you pumped the brake pedal down to get the pistons fully against the pads?  Were the sliding pins OK, not seized?

Otherwise, probably just need bedding in.

Not quite sure what you mean........undid the 13mm bolt and lifted the caliper up to change the pads.....replaced the bolt as supplied with the pads and tightened to 30nM......
Was the caliper free to slide from side to side?

Im a bit of numpty........so dunno  ::) it seemed free to me.........but if youve read my other thread....the pads on drivers side were down to metal on metal.....passenger side only a bit less than 50% worn..... :-/

It might be a sticky caliper  :-/
Both pads and it's the piston, although possibly the other caliper.  One pad it's the sliding pins.

The leading edge of the pad should be chamfered (from the factory).  Reduces bite, but also the squeak.
