I already mentioned the slightly different intake design, but this is shared among all GEs. I know the intake manifold itself is also shaped a little differently.
The main difference is the i-VTEC head on the GE L13A and L15A. The GD L15A's VTEC is basically a valve-idling mechanism...below 3500 RPM the engine uses only one intake valve per cylinder. The i-VTEC head adjusts timing and lift across the whole range.

Other differences would probably involve the wiring as Jazz it up! has stated.
Temple of VTEC Asia has detailed technical write-ups on the GE L-series engines if you're curious.

More power in stock form is always good
