I check in Belgium and in Germany and they offer engines for about 2500 euro...so it can be done.

There really isn't much difference between automatic and manual engines. Mainly vacuum connection to intake. So manual 4.7L S engine will work and current 4.5L has probably all automatic gearbox related parts which can be used again.

thanks for your extensive research, guys. I'm feeling a lot more confident for replacing the engine now. Would you advise are rebuilt engine (is ofcourse a lot more expensive) or just a used but good engine with not too much milage ....

I bought an motor out of an S car that had been brought into the US. At the point that I purchased it, it had a US 4.5l block, but a 4.7l Euro S top end (heads, cams, intake, etc). I assume there was an issue with the short block so it was swapped out. I suspect there is a good chance that this happened to your car as well. Most of the difference between the Euro S and the 4.5l motor is in the top end, so I really cant see why anyone would swap the whole motor when the they could just swap the short block. So, I would suggest that you take a careful look at what you have before you make any big changes. I don't have dyno numbers on the 4.5 short block, Euro S top end combo, but it is pretty nice at the seat of the pants, and if this is what you have it might not be worth changing your motor. If you post pictures of your motor we can tell if you have a Euro S intake, at least. The heads you will have to check by part number.

Start with pictures and more ID numbers, casting numbers on intake runners and heads.
Changing engine and transmission seems odd. Does it have a instrument cluster for an AT with the gear selection I think in the lower part of the tach?
With a used motor, even low mileage, its still 28 years old or more, I would pull the heads and have them refreshed and reseal the whole engine as well as checking bearings and rings for wear.
Did the early Euro S get the higher stall torque converter?

What's a stall torque converter and where is it located ?

I suspected that :-( .. but hey this gives me the opportunity to check and arrange my engine and AT properly so that I'm sure everything is in good order when cruisin' on the German and Belgian highways :-)
