Title: engine and box change
Post by: Jaymd on 12 December 2010, 15:17:10
I am looking at changing the engine in my 2.2 16v Omega for a 2.5 v6 engine and box, its from a 99 model omega, will this go straight in and run in my car? Any help guys, much appreciated.

you will need to change the engine loom, ecu (with matching chips and barrell reader) 

you will also need additional parts,

exhausts with heatshields for the other side of the floor,
Air intake system, front struts and springs (possibly just springs)  160mph speedo, gear lever and linkage (reverse is in a different place on gear knob) 

and a shed load of time, theres alot of other stuff that i can remember or have time to write here.

so the car better be a minter or its not worth doing.

IIRC the 4 cylinder engines don't have traction control, the 6 cylinder do.

The traction control is triggered by the ABS ECU. The ABS ECU was changed from a 3 channel system to a 4 channel system when the mini-facelift was launched (1998 ish?).

I don't know if the 4 channel ABS ECU can be programmed to talk to the earlier engine ECU :-? Maybe it doesn't matter, the engine ECU might work fine without it :-?

the v6 ecu will run with the 4 pot abs ecu, but the 4 pot ecu wont run the tc unit.

hence why the 4 pot abs system is prefferred for v8 conversions etc.
