The Z32 Pistons work, but due to the difference in cylinder head design your compression ratio will be lower. if you are looking to achieve 9.5:1 CR you would basically have to get custom pistons made.
the only pistons available for Z32 off the shelf is
8.5:1
9:1
10:1 (N/A)
11:1 (n/A)
I would suggest the 9:1 TT pistons to leave you with a nice CR for high boost, otherwise I would highly recommend talking to the guys at CP or Wiseco for a custom set.
