Questions about 3.1 in a Rodeo 4x4

[Bad Monster Olds]

New guy here! Have a few questions about the 3.1 in my Izuzu Rodeo. I spun a rod bearing was considering rebuiling the engine.

Does anyone sell a complete engine kits for these engines? I have a 3.1 from a 94 Bertta, would the intake plenum and head interchange between the 2 engines? Is so what mods are needed? Also would I need the engine harness and computer setup from the beretta?
