here's a short list of differences, and i KNOW i'm not getting everything:
intake manifoldexhaust manifoldwiring harnessoil pan and pickup locationvarious sensors, connectors and plugsengine internals accessory brackets and pulliesmore?
so basically, what you are looking at as far as the EASIEST way to swap the engine in is re-using the intake and exhaust manifolds off of your truck so most/all of the truck harness/connectors can be re-used (maybe, these should at least bolt up the same - or maybe not), modifying the block's oil pan and pickup location to work with the truck, and using the truck's pullies and brackets (if they will bolt up correctly) to locate the accessories correctly...
and having to deal with the difference in the power band (?) from the different cams and compression ratio. im not sure of the exact differences, but im willing to bet the frontier KA makes more of its power lower in the rev range.
then you have to deal with the 97-98 240sx's were considerably fewer in number than earlier years and as such the engines you will find will be more expensive. maybe not more expensive than a 2000 frontier, but i'd think that since the KA was used in earlier model frontiers, too it would be easier/cheaper to go this route and you wouldnt have to work so hard to adapt everything.
i think.
