l-jet is to cars like an abacus is to computing.
Motronic, on the other hand, is a PC at least. A few years old one, but essentially the same as the latest models, although somewhat slower and less sophisticated.
Changing will need a loom change, mainly because the ECU plug has many more pins, and a fresh oil pressure switch, because the plug is different.

Motronic 1.3 came with the 1988-on models of 320i and 325i. Prior to this, early 325i's used Motronic 1.1 or similar, with pre-1988 320i and 323i models having analogue L-Jetronic.
