On 7th gen civics, the fuel flow stops at the fuel rail. The distributor itself is a totally different technology. Yes, the firing order maybe the same, but the coils are designed to react different from its predecessor. Firing signals are controlled by the ECU itself. So, if you really want to do this swap, you are better off using everything from that D17a1 motor.... include the motor harness and ECU with it. Now the challenge relies on trying to convert your accessories to work.... such as gauge cluster operation and lighting....
he could always use msd stand alone ignition management. the fuel system could be tackled just like a k-swap. use an external fuel pressure regulater and its own return line fed into the factory return line.... ta-da magic
