Engine swaps

[Mad_Aussie]

Hey guys

Got a technical question for you all..
It just so happens I can get my hands on a 2.3 MPS engine for a fairly low sum, and want to know what differences/similarities it has to the 2.0 Duratec HE in my LS.
I'm under the impression that they are essentially the same engine with a different head (talking about the 2.3 in general, obviously the 2.3T would have different slugs etc).

If I were to get the complete engine + loom + ecu, is it essentially a bolt in job, or would I need the whole half-cut for engine mounts, accessories (steering rack, gbox, etc)? I presume I would need a higher-rate fuel pump - either the standard MPS/XR5 pump or a bosch 040, but just looking at the engine sitting on the pallet it appears to be very similar in dimensions.

And on that topic, if I were to instead think about an XR5 wreck, would it be a case of parking the cars next to each-other and doing a straight swap over? Or are the german xr5's fundamentally different to the Seuth Efricen standard Focus?

Just want to test the waters before deciding on this engine, don't want to be left with another useless paperweight in the shed.

By the way, if this has been covered before, please link me through to threads, certainly after a good read on the topic

Cheers!
