Can the oil pump from a 4BD1 be used on a 4BDT2 with no issues?

I just did the reverse swap. I think you'll be fine.

Be aware that Isuzu changed the oil pump when they made other engine changes sometime in 1988. They increased oil cooling for the pistons and so the later pump (also changed to gear type) delivers more flow.

I don't know, just guessing that they may have carried this through to the 4BD2T.
