Just wondering if any 1 could help me with this. Ive got a 2.5 mv6 omega which i took engine out as it didnt have enough power . Its a drift car with everything removed roll cage hydro handbrake etc. anyway i bought an ex police omega 3.2 mv6 an was wondering will it put in my car ? Before. I go an take the engine out ? I have both cars sitting side by side my 1st one is 1998 an the cop one is 2001 facelift estate. Thanks

That could be a mare, as its going to be a pain to retrofit the engine management from the newer car.

You could use the old engine management, but would need some effort around throttles, EGR and SAI. Plus the mapping may be too far off?

AS TB implies .... 2.5 is cable controlled throttle etc ... 3.2 is "drive by wire" electronic controls ...... big difference in hardware fittings ...

[Jamesm]

Both ecus are in the same place. Cud i not just take ecu an loom out of police car an put it in my car ? And take ignotion barrel and key to ?

[serek]

if you replace bare engine then you no need mess around with wiring
EDIT:
its an easy swap  drop me pm and i can explain all

[Jamesm]

When both engines out would throttle issue not be easy sorted ? Change the intake in throttle body ?

That would be easiest solution, thus keeping the original engine management system.

You bolt the old engine management system, sensors etc to the 3.2, simples.

[Jamesm]

Thanks lads. So i take the engine manafement outbwith the 3.2 and put the lot into old car ? Also is there any ways of tuning the engine to up the bhp ? The cheapest way lol

[Marks DTM Calib]

No, you fit the engine management setup from the 2.5 to the 3.2 and then fit it

[Jamesm]

Will that work just set the 3.2 in and plug the loom in to the ecu ?

[feeutfo]

Thinking aloud....

So keep the cam covers plug leads and sensors with the car?
So your just fitting the block Auxiliarys and heads?
As I understand it?

Manifolds, cats and exhaust from the 3.2
Bin the egr leaving the sensor electrics working.
Use 3.2 inlet?
2,5 plenum with throttles and icv

?

[Jamesm]

Im confused lol

Remove 2.5 from car, leaving loom, ecu and throttle cable in car.

Take all the sensors, coilpacks and throttle body off the 3.2.

Fit 2.5 throttle body, sensors, dispack and plug leads to the cleared 3.2.

Refit 3.2 into car, plug all the wiring back in, and reattatch the throttle cable.

That's it, nice and straight forward, and imo a waste of a 3.2

Only tuning would be 3.0 throttle body and ecu. 3.2 has better exhaust manifolds, but you are already fitting them with the engine. May as well fit the whole 3.2 exhaust too.

Yes ignore me for a minute, I'm fuddled too.

Just trying to clarify the details really.
