Yes my idea is mount oem and later as with the time make changes.
I have one post in 914 categori of my car and is :
http://forums.pelicanparts.com/porsche-914-914-6-technical-forum/629894-conversion-914-6-gt.html
But I have now two 911 aircooleds and read this categori every day 4 or 5 times and for a question of 911 engine this is the best place I think.
Thank you guys
and one pic of my two 911
