http://forums.pelicanparts.com/uploa...1180853107.jpg Why is the Aftermarket piston 89.98 There should not be that value. |
What is it you are trying to determine? You have the measurement of the pistons. They seem to show up (at least very close) on your charts and a "2" for the Carrera RS chart. They also are the same size as the "1" on the 74-77 chart but so what. They are clearly 73 RS pistons. If you look at CIS pistons you'll see the difference.

There should not be a 73 Carrara 2.7 piston with 89.98 according porsche charts.

You're right the number is 89.975 for the maximum on the "2" size. That is what I mean't by "at least very close" in my post. You are looking at a .005mm difference.
Are you trying to use these? Are you trying to replace them? Are you trying to buy new cylinders? What are you trying to accomplish? -Andy |
