This interests me, too, because I recently got a good deal on some parts, including an injector pump from an unknown year. I have a 1980 300TD. I just phoned the guy I got it from, a very experienced foreign-car mechanic in the S.F. Bay area, and he says the N/A and Turbo IPs are not compatible. "The fuel delivery is completely different." Sorry about that. He said mine is from a 1980 N/A, so I'm in luck if I ever need it. Maybe sell yours on e-bay... PEH is right again !!
