Compatible engine swaps for a Mazda B2600i 4x4?

:
1993 mazda b2600i 4x4 5 speed
I just bought a 83 Mazda b2600i 4x4 5 speed and i want to put a bigger engine in it. it has the 2.6 now and i want to put preferably a straight 6 in but I don't know what motors will fit, i also want one that will bolt in with little or no modification and keeping its current manual transmission.

Are there any motors like that and if there is please let me know exactly what to look for. I've looked online and the je v6 is looking to be pretty much my only option for easy swap but id like to get one from a b4000 cause I've had one b4 and it was a good little truck.

Can anyone out there help me figure this out and average cost of a new vs used, thx in advance!
