I suspect the pumps are different, as the computer controls the timing on the 2L-TE. I don't know for sure, though, and I don't know where you'd find specs. You might have some luck posting your question over on the toyota diesels forum at www.toyotadieselmadness.com. Lots of 2L-TE drivers over there - and quite a few that have done conversions and so are pretty familiar with the engines.
