as far as the ECU quesion, if i am not completely mistaken, the 95+ 240's used an OBDII setup, meaning that your '91 ecu will not neccesarrily work with the new motor (at least not without some add'l wiring). Just my .02, it seems that the best bet would be to get the newer ecu & approriate sensors for the new motor as well as the full wiring harness to accomodate.
-then again, i hate splicing wires.......
