yeah ive been looking into the swap a lot myself. I thought hey it would be awesome to go with a euro motor. The mechanic masters james mentioned has something for around 12g that is the motor 6 speed tranny etc... everything you need... install is harder on these because it is european though trust me... me and dwrx04 are helping his cousin put a jdm b16 into his civic and everything is different than usdm... anyways i think you would be completely satisfied with an ud 3.0 or 3.2 m3 swap.. Mechanic masters in spokane quoted me at around 5000 with install for the whole swap a motor with 50-60 k on it i think tranny etc... you will need to buy a new diff which isnt that bad... check out diffsonline or a junker... if you get the us spec m3 motor it also opens up the possibility of doing it yourself.... If you are mechanically inclinded have the patients and can accept that you might mess up you might want to go that route... would be very rewarding when done... Me and dan (dwrx04) have thought about doing my swap ourselves over a week or so... save me a grand or so... but we have yet to decide, between the two of us we are capable and his grandpa can do all the wiring, so we are set there... Either way good luck with which ever swap you go with. YOu will find out the euro swap might end up costing you around 15g. haha where as us will be 5grand installed....
