Yes, you will need the 6 pin CDI to match the distributor. I am assuming the euro dizzy has the magnetic pic-up and not points. Two different technologies.
You will need to create a new ignition harness and re-do the wiring below the engine compartment electrical panel. Including re-doing those 14 pin connectors to do it right. Porsche changed the way the CDI box was wired to the dizzy between '71 and '78.
I did a write up on this many years ago. I'll post the link when I find it.
I can post the wiring for the 3 pin, but it will do you no good.
The HOPEFULLY you have the tach adapter on your car. If so you can just wire your tach to the coil and your original tach will work.
The silver can to the left is the infamous "tach" adapter used only on '70.
