list of things needed.
Engine
gear box
3.2 ecu ?
diff ?

why not just buy a 3.2 less hasstle

Assuming yours is auto, engine/box and diff and loom. Just unplug 3.2 loom at ECU and plug into your ECU. 3.2 will run with the 2.6 ECU

I see where he's coming from. Pauls has done a lot of work on his car that's not engine related. Arguably, its easier to swap the 2.6 for a 3.2. Than do all that other work again. ...it's the devil you know.
Personally I'd keep the 4.22 dif of the 2.6 though. :)
-
So list is..
engine
gearbox
ecu+loom
Plus some nice oof person to fit for me.
O well something to think about.

As said ^^^^^^^^^^3.2 will run quite happy with 2.6 ECU

Don't need the loom either :y electrically they are identical :y

For ease of installation Al

Either or... :y
Leave the loom in the car or swap it from old engine to new or just swap the lot over :y
Personally I would keep the 2.6 loom if the car currently has no gremlins...

As Chris said above I have done a lot of work to the car but just want a bit more power. I have looked at other 3.2 s for sale but that would mean I would have to start all over again with a car I dont know. If I just change the engine,gearbox at least I will only need to keep an eye on them :y

Ffs all your doing is an engine and box change. Out with the old in with the new.
unbolt propshaft from gearbox,unplug lectrics, undo and remove downpipes.
remove bonnet,unplug lectrics,unbolt mounts,remove radiator pack, disconnect battery,
then remove, installation is the reverse of removal...

No need to remove bonet even, provided lift strap is short enough. ;)
-
It's also a good chance to re seal the sumps and make it a bit more oil tight in the usual places. Inspect the bottom ends and make sure the sump pick up is clear, all while the engine is out.
-
If you want to do a proper job, then before dropping the new lumps in, fit new crank sensor, new hbv and a thermostat and cambelt,and as you said take the sump off, lot easier to do all these jobs on a stand than in the car.
and the reason i said remove the bonnet,was when removing engine and box as a unit it gives more space when lifting,to get the clearence on the slam panel,.

8 bolts and a four post lift and you can drop the engine straight onto the floor ::)

I like that idea better :y

yes you can do it that way, thats how they are assemblied,and its the recomended GM workshop way, but what happens when you drop the subframe off the car. ???
-
I've always done it the "over-the-top" way - I just find it easier.
There's no need to remove the bonnet, but I usually do, just in case.

Raise the car slightly. Take the weight with a hoist, undo the wiring/ bolts and use the hoist to lower the engine etc onto a trolley/ pallet and raise the car clear. If you carefully mark the floor and the trolley/pallet, you should be able to refit the subframe exactly where it was :y
In reality though it will be done on a driveway in the rain, just like every other job :D
-
I usually chop the slam panel out to make things easier,but that may not be such a good idea in this case. ;D
-
Removed carefully, the slam panel can be reused, clearly much easier if you can take a grinder to it though :D
-
on the note of engine changes is another better box available that can fit the omega (im thinking 400ftlb or so?)

my swop question is similar, fitting a 3.2 to a 2.6,
could the 3.2 be used and keep the existing 2.6 gearbox?

Yes in the short term, although if the 2.6 is an auto, then it's probably an AR25, which the 3.2 will eventually destroy :-\
Ideally you need an AR35 from the get go, electronically the same, but stronger internals :y
Same applies if it's a manual... R25/R30 :y

Thanks Al.
Yes its an auto.
It wont get used much so would take a chance on the g/box surviving the new engine.
Anyone breaking a 3.2 and have a good engine available?

What do you do with the air con compressor ?
When I lifted the engine out of my old 2.5 I made the mistake of believing Haynes when it said I had to get the air con degassed and disconnect the air con hoses.
I was told afterwards that there is enough play in the pipes to allow the compressor to be unbolted and tied to one side >:( (don't know if it is true, I only had the engine out once :-\)

why go for more power if its an auto ?

Because an auto 3.2 still knocks the skin of a manual 2.6 pudding. ;) ;D

I suppose I'll never get it.
To me, ticking the "auto please" box also means you'd have ticked the "I don't care how fast it is" box.
BTW Chris - what are your shifts looking like over the next couple of weeks ?

Ooh now Mr 2woody, what was it you said about last time after the drive down. I did feel your pain.
A manual is pita here abouts, as you know. Without adding Edwardian engineering into the driver involvement pack.
If the omega manual was decent and the auto poor, I'd agree. Fully.
The reality is wite the reverse though, sadly.
