83 pup motor swap

I need to do a motor swap on this truck, it has a1.8l in it, please help...

i dont know about there in the states but here the later model isuzu/rodeo has a 2.6 engine that uses the same mounts..

my 93 has a 2.3 in it but some have the 2.6 which is fuel injected. i know the amigo has a 2.6 but im not sure about all of em.

If I went with the 2.3 does it come with a carb or inj.
