I am planning to rebuild my 1.8L to a 2056L using the stock L jet fuel injection. Can you replace the 1.8 injectors with the 2.0 injectors? Would there be an avantage in performance?

L-jet uses a resistor pack in the circuit to drop the operating voltage to the injectors, D-jet doesn't. Doesn't matter to me what your book says, I don't think they're interchangeable. That means BMW, Nissan, Jaguar, and other L-jet injectors won't work either, no matter ho much you want them to. BTW, is that the same book that says 914s use the SR-15X?

D-jet DOES use resistors on the injector circuit as well, they are just internal to the ECU rather then an external pack. If you open a D-jet ECU they are attached to the top edge of the case. I have measured them from 6.8-7.2 ohms depending on the ECU, and have reused them in megasquirt installs as they are the exact value the megasquirt calculators tell you to use with 2.5ohm resistors. I would bet money that if you measured an l-jet resistor pack it would have a similar value.

Still though, I dont think i would try swapping them on a stock setup though as it would be to much of a PITA to tweak everything else to work with the different flow.
