After the last thread where people were talking about a group buy of hyundai versions of the 4d56 (the D4BH), I looked up the hyundai website, and saw this interesting motor:

The A-2.5, which seems to have slightly smaller physical dimensions, but a 40% increase in power over the 4d56.
(HP: 138hp for the A-2.5 vs 98hp for the 4d56, Torque: 253 vs 166 ft-lbs for the 4d56)

(for comparison, the D4BH page is here: http://www.hyundaiengine.com/auto_diesel/06_d4bh.html )

Now, I've always been a 'keep it stock' kind of guy, but I know there are more intrepid souls on this board... So my question is for those people: what sorts of issues will I have to deal with when trying to put a motor from a different manufacturer into a vehicle?

I imagine the motor mounts will be different - how does one fix that?
Most likely the tranny won't fit right - how do people tackle that?
The specs on this seemed to say something about an ECU - how does one incorporate that into a mid-80's vehicle?
Will I have to seriously consider whether the drive train can handle the extra power?
