Yes. Actually even my '89 9000 has upgraded software.

No, they are not :). The very basic engine (=the block itself) is the
same, yes.

Nope. The 123d has two turbochargers. The 120d has a bigger
turbocharger, different injectors, IIRC different crankshaft and some
other differencies compared to 118d. 118d and 116d may possibly be the
same engine, I haven't found theier differencies, but I'd guess that
they too have different turbos.

Yes, 1-series was one of the possibilities I though about, so I did a
little digging :p.

I'd say that if it's done correctly, the reliability shouldn't be a
major problem on that engine (especially 123d). But the software I
referred to is a official software (by Hirch), so it won't trash the
warranty of the car.
