Hi Nico, Welcome!!
I remember this car for sale. Congrats on your purchase. If you have the time and patience and $$ you can return the car into a lovely SWB 912 keeping the 2.7 engine. Dont forget you can sell the wheels body parts etc etc. There are lots of early Porsche guys in Sydney that can give you great advice.
Try to go to some Porsche club events, historics etc to learn and get some inspiration.
I wish I had a project like this when I was 19
