So ive been thinking about replacing my 2.2 engine in my omega with either a 2.5 v6 or a 2.6.  Ives done a few conversions in my time, but never with an omega. So whats involved in changing them, apart from the obvious loom, mounts, ecu etc...

Just buy a V6 ....  far easier in the end.

+1..
 
not worth  all that work..

I could do that, but not what I asked. I have a v6 engine lying around, just wondering if theres anything else I need.

I know ............ I made a constructive suggestion - just not worth the effort IMHO. Are diffs the same, is your gearbox the same, are all the exhaust hanger mounts there.

IIRC the backbox is the same for a 2.2 & a 2.6 so the backbox hangers will be the same. The centre sections hang on a bracket bolted to the gearbox mount so not an issue if the OP has an R25 gearbox (and all the brackets) bolted to the back of his engine......

Yeah, thats what I'm asking? I'm assuming I could use the 2.2 diff and would just have to change the front half of prop for the v6 box

Exhausts are the easy bit really, bit of cut and weld would fix it.

It's really not worth the hassle, given Omegas are so cheap, why bother? Just buy a V6. What's the reason for the change?

when you drop the v6 in and start to have electronic problems , it will be too late to give up..imo..

Why does your original post say 2.5 or 2.6 as in this post you state you have an engine lying around surely you don't have one of each on your front lawn 


But long term i agree with everyone else just buy an Omega with a V6 unless you want a serious project on your hands.

I have a 2.5 in my unit. A good friend of mine likes his v6 vectras so has a few 2.6s lying around cheap. The 2.2 is too underpowered for drifting and fitting a v6 would cure that. My car also has a long mot and tax, and is a very clean shell which I got for very very cheap so dont see the point of selling to buy a car I know nothing about. Plus buying one thats already a v6 takes all the fun away from it.

Why would I get electrical problems? id be changing the whole loom and ecu

Issues would likely be upsets with other ECU's which communicate.

If yours is an auto - the TCM will have the wrong map and not be happy.
ABS - different unit and config again, eg v6 has TC, 2.2 doesnt
MID - Config will be wrong, easily changeable with tech2, whereas not sure the others are quite so simple.

Could be a fair few grumbles to sort.

Mines a manual, abs will be getting removed
