I know people that have:
swapped a Hemi into a Wrangler
swapped a 5.0l into a Wrangler
swapped 350 into a Wrangler
swapped a 5.0l into an Izusu Amigo

The 350 is the cleanest swap.

So, if you are set on a 5.2 you probably should look for a donor older than 1996. That is about when the OBDII came into production. It will complicate your swap having to deal with the sensor inputs. For more info, see: http://www.obdii.com

OBDII ushered in the shift from hydraulic to electronic control transmissions and a host of sensors.

Unless, you can get the entire combination of computer, engine, transfercase, and transmission. Then, about any year will do.
