I only have reliable records that go back to MY72 but for ever year and every street car modal 911 the steering has been a ZF 17.78:1
964 p/s went to 18.75 and 993 p/s went to 16.48 except for 993RS p/s which was 18.25
there were some small difference is steering wheel size, scrub radius, camber and caster that all leave a bit of an imprint on steering feel from '72 to '89 but not as much as the imprint of the polar moment increase
Porsche actual went out of their way to increase the polar moment of the very early cars by adding bumper weights and eventually the the batteries in the front corners, eliminating all of that w/ the G Series car and newer
