I can't find anything right now about an M/S 50/52 in a 2002. I've seen the S14 in one, but I'll keep looking.
I seem to remember something about the water pumps with the S52's (is that the right engine?) and as always, I would do my research, and do as much maintenance now, so that you won't have to do it 500 miles down the road, right after you finish your project.
Keep us informed, I hope to be putting the same engine into
