The only difference between the 3.0 and 3.2 that is significant for retro fitting is the engine management, its much easier to keep the ECU setup from a 3.0 than it is a 3.2.

I have said many times that the optimum setup using off the shelf bits is a 3.2 bottom end and exhaust manifolds ported 2.5/2.6 heads, 3.2 inlet setup and 3.0 engine management  :y

What’s so special about the 2.5 2.6 heads :)

Smaller combustion chambers which will raise the compression ratio. :y

Still wondering how it over-revved when the ECU includes a rev limiter. :-\

Finding first instead of fifth from fourth above motorway speeds will do it :D

Apparently the engine is the weak link in the drivetrain...

What can be done with 3.0 engine management that can't be done with 3.2? I didn't think either were easily re-mappable these days?

2.5/3.0 can be readily chipped, 3.2 less so.

Although I believe the 3.2 is remapable.

Zirk is the person to ask for this, but the results can be mixed iirc :-\

Certainly, MSD and Irmscher both did off the shelf chips for the 2.5/3.0.

One of my plod Omegas had a full service history, including defect reports and job cards 8)

Defect: Mid pursuit on A34, mis selected 1st from 4th under hard acceleration. Loud bang and loss of drive. Lots of smoke. Won't restart.

Jobcard confirmed total engine destruction, new engine and clutch fitted (with paperwork), roadtested and returned to service.

The manual Omega will take alot of abuse, but try rushing a gear change at your peril.  :D

Should be: Clutch down. Move lever. Clutch up.

But if you try: Clutchmovedownclutchleverup. It comes out of gear but hits a wall. Forceful wiggling will eventually get it somewhere, but unless you put the clutch back down, it probably won't end well :D

Hi All. The y32se conversion is epic. I sprint and drag race very effectively. How do I get pictures added? Here. Do I need to host elsewhere and just post links ?
