A friend of mine has a 6.5 v8 diesel in his s10. So a 4bt 3.9 cummins would be good also. For a cummins you would need a adaptor plate. and a torque converter (If automatic)for a diesel.

I remember back in 1984 and 1985 when s-10 came factory with isuzu diesel 2.2L. I wanted one but they were hard to get and only came with a stick. I wanted one with a automatic. And I don't know if one ever came with a automatic. That would have been a sweet ride. Also I remember they only came in 2wd. 4wd wasn't a option that I know of. If it came with 4wd and a automatic it would have made a good little truck for plowing snow.
