Hi all,new to the forum
Im just wondering what engine will fit in my omega easily.do cavaliers etc fit?currently there is a 2ltr ecotech in it but its on the way out,so im thinking about upgrading? any help appreciated
Thanks
-
Given the low price of Omega's is it not easier and cheaper to buy one with engine already fitted?
Its going to be a lot of work to retro fit a V6, so not really worth it. If you are going to fit another engine my choice would be to shoe horn a LS1 V8 in. :)
-
im in ireland and cant see anything that cheap so far. theres test on the car too until march so thats why i thought stick sumtin good in if it fits/works easy

Hi. Welcome to the forum. :y
Might be better to fix the existing problem(s).
There is a tremendous amount of knowledge on the forum across the different models. If you do need to bin your engine then it is likely that one of the breakers on the forum has a suitable "same" 2.0 engine.

Replace with the same engien type is the easiest, same power plant (minor differences on ancillaries which are easily swapped) used in the Astra and Vectra.
Or maybe a LET engine?

Very tuneable for not a lot of dosh :)

whats that now? sorry as i said im new :)

LET is the engine code for the 16v Red Top Turbo engine found in the old Calibra/Cavailer. If you fine a cheap one of these budget for a complete re-build as 90% of these and normal red top will have been thrashed to within a inch of going bang
The block for an Ecotech Vectra, astra is the sames block just use the Omega manifolds etc

or the z20let which are newer and more plentiful

that sounds good andy,thanks. i actually might no where theres one!

I have a Swindon racing V6 in mine - you can have that for £500 with the rest of the car still attached! :y

What's the output on that ?
-
TBH I havent rolling roaded it as yet.
The spec sheet from Swindon says 206BHP but I've fitted 3.2 manifolds and had it ported a bit since then.
My guess is about 220.

That's a 2.5 right ?
Does it use a stand alone ecu ?
Sorry to the op for the thread drift :)
-
It's on the original ECU so there's room for more gains yet.
Nuff said on this thread though - I have a for sale thread for the car so any chat about it can go there.
Sorry for the thread-jack :P
-
most of the bigger omegas seem to be autos :( so what exactly will i need to do if i change? im just trying to get an idea if itd be worth it,i can probably get a friend to do the work
-
Just remember that If you fit a different specification engine it will in effect become "modified". Your insurance will certainly jump up. Not because of a bigger engine or anything, just the simple fact that a modification has taken place is enough for a premium hike.
-
im not worried about that, but thanks anyway. just wondering will any engine fit without much hastle,(eg) CAVALIER,CALIBRA etc??
-
Cavalier, Vectra, Astra, Zafira and Calibra all used variants on the same 2.0 16v engine but being front wheel drive they will have different engine mounts, sump pans, dipsticks and one or two other bits.
They can all be taken from the engine you take out of the Omega and fitted to the replacement.
It's a couple of hours of easy work to swap it all over - even easier if you have an engine stand.

will the ecu be needed??
-
If you already have the same spec engine in the car then you can just use the existing loom and ECU.

Thanks for all the help. Last question now i hope, will a 2.2 out of an auto fit my manual?or will it have to be modified?
-
Yes but you will need to fit the flywheel off the manual engine using new bolts, and you will need to fit a spigot bearing.
Total cost about £20-30.
