The 1st-gen CRX will fit most or all D-series drivetrains. However, the mounting points are different, so it definitely is not a bolt-in operation. Also, the DX (or "standard") and HF models were carbureted, and used a different fuel supply setup than the fuel injection uses. So a fuel return line has to be added, in addition to any other changes.
It's definitely doable to swap a very FE D-series drivetrain into a 1st-gen CRX. It is easier to swap into the 2nd-gen car, though.
I'm guessing that the 2nd-gen shape is more aerodynamic than the 1st-gen one, but that's just a guess. The 1st-gen is smaller and lighter, though.
