Brant, actually all the early motors (production of course, I am excluding chromal and exotic prototype stuff) until the introduction of the 911T in 1968 used Biral cylinders. Nikasil came in with the 917 in 1971 and was used in the production cars from 1974. ('73RS was Nikasil)
Tom Butler is correct.
