This is my first Porsche ever and first time on this forum. The person I bought this car from said the engine was not the original and was not sure about the transmission. Where can I get help in determining what year the engine and what model transmission it has. The car, Vin #9116201816 has engine #6150843 and transmission #7165145. Also, where can I find out the original paint code or specs.? What was the original decals on the rear lid? I am anxious to start my new project! Thank you for your help ahead of time!
