Omega General Help / Re: Omega 3.0 to 2.5

I would want to check the 30 cams carefully. If the crank sized due to oil feed/pressure problems then the cams could have picked up as well.

Jep, have been thinking about this one too  Just need to take the engine apart as quick as possible to see the situation down there...

Found this http://oldsite.omegaowners.com//forum/YaBB.pl?num=1297252936

And now im considering a Saab 3.0 engine without a turbo. It will have like 20 hp less in non-turbo version because of the low compresion, but this engine is way easier to get.
How do you think this will also be a plug-and-play swap or this could turn out worse because of the different ECU that Saab is using? Or better just to put a 2.5 in it?
Anyone done it maybe?

P.S.
Thanks to everyone for sharing opinions

Thank you all for help, its very useful! 

Maybe there is some other bits that I should check once the engine is out? Any typical V6 problems? 

Ohhh and the most important thing - where on the engine i can see  which  engine is it? Is there a code or name on side of the block like other cars? Heard something about different intake manifold pipe sizes too.
Just heard from one of the local scrap yard worker, that most of 3.0 engines for sale in my area are 2.5s, but the sellers think they are 3.0s and try to sell like one of those

These are nice news, because current engine has new alternator and starter motor and I was hoping to use these. 

If i change sensors, i can keep the 3.0 ecu, correct?

And what type of chips should be swaped?

Omega General Help / Omega 3.0 to 2.5

Hello everyone!
Recently had been offered a really cheap x30xe Omega with auto gearbox. Previous owner had oiling problems and now the engine is dead. He says that the crankshaft died because of the oiling problem.

Its difficult to find a 3.0 engine, but the 2.5 is really cheap, thats why im thinking about swaping those.

So the question is: Does the 2.5 engine fit to 3.0 auto gearbox? What else is different between these two engines and what other parts do i need?

And maybe i can just take the botom from 2.5 engine, leave the 3.0 heads, so i dont have to change ECU and do the wiring?

P.S. Sorry if the questions are dumb, i just never had to deal with omegas and wanted to know wich would be the easiest and cheapest solution.
Will be thankful for any advice.
