Trying to calculate compression on ITR motor...HELP

I am trying to buy some pistons for my car and CP, wiseco or these other companies dont have specific forced induction pistons for my ITR motor. How do I choose which pistons to use? My motor is boosted and I am trying to do a rebuild with about 10:1 to 9.8:1 compression. And I am planning on using eagle rods.

Exactly. The B16/GS-R/ITR 81-81.5mm compression pistons fit your application. No need to go down to 9.0:1 as long as tuning and fuel areas of the build have been addressed
