Thanks
This is not a M96 engine, it's an M97 engine. You'll run into different problems.

Go for an M96 engine. Some early cars of the 987 had an M96 engine. It has 3199 ccm.

IF the part numbers on the DME are different? If they are not the same - define all the differences and their significance. Then detail how you will adapt to make compatible.
If the OP is proposing swapping engines complete with DME and all wiring ,that is different but maybe there are still issues ?
All I am saying is do the research first. Engine swaps in modern cars can become fiendishly complicated. And then there is the Smog Test issue. The new DAD machines interrogate for DME configuration+VIN. If there is a mismatch it is automatically flagged,fails and is Referee only. You don't want to go there inadvertently !
Markus is right. Keep looking for the correct engine.
But if the swap works ( & I hope it does) be sure to let us know because we need all the options we can get for swapping in replacement engines.
Good Luck !

I have done this. My 2003 has a 2006 M96 3.2 engine. As Qmulus said, its a simple swap, the only thing to change is the crossover T which has an additional valve on the 2006.

No other modifications needed.

If you want you can put the 03 scavenge pump on the head an use the vacuum system complete from the 03. I put 06 heads on my 04 block this is how I got around the difference in the Secondary Air System.

Great Info!

I originally was looking for a direct swap from an 03 or 04 however the salvage yards were all looking for between $6-8k for high mileage engines. I did find a low mileage engine from a 06 S with the 3.2 for $4k the engine will hopefully be here on Monday and I will do a complete write up on the swap and update this thread

Thanks

This practical experience trumps all the speculative ramblings of others (inc.Me) !

Yes, if it's a M96 3.2, but not if it's a M97 3.4.

And if you have time, tools, skills and money to built an own engine version (mixup of M96 and M97)… go for it. But in my honest opinion this is more of an engine rebuilt than a simple engine swap.

Regards, Markus

I tell a lie - you also need one of the coolant hoses from a 987 to mate up with the slightly different outlets
