4 door engine swap question

mmm- kay! my question is, does anybody know what mods need to be done to swap my d15b7 out for a D16z6. i checked a site: http://www.enginereplacement.com/htdocs/chart.htm they have a chart which shows which swaps can be done easily. and for 5g ( 92-95 ) it has an x, so i was just lookin to see if anyone has put a d16z into a 5g 4 door.And if yes, what mods were needed. mounting brackets, wiring harness etc.

The EX 4drs come with the z6 stock. You need the engine and ECU, then you need to wire in vtec: http://www.hondaswap.com/~pills/obd1guide.html (You only need the vtec part, the rest is meaningless for you application). And that's it, the rest you can use your existing parts (mounts, axles, etc).

so its just a simple swap, dope. now im curious why they put an X in for the spot on that engine swap site. Thanks for the reply civicspoon!
