Actually, the highest compression pistons available in a US delivered car are 10.2:1. As for the rest of your question, I wouldn't have the slightest clue since I don't know what-all you've done to your engine.

I had an 88 with 10.2 pistons. The 10.9 are euro pistons. I am sure there was a ton of them imported into the US but dont know what the bench mark for ITS is on this sort of thing. The rest of the engine is stock except for balancing the rods and perp drilling the crank. The 944 runs as a limited prep car in E/P so they dont allow killer mods to the engine. The current engine in my car may make 215hp at the flywheel but that is with a stand alone computer and other tricks. Thanks for the help.
