Hi m30 Gurus. I’m about to pull the trigger on a set of cp Carrillo pistons in prep for a turbo in the future. The only thing is off the shelf I can get a set with all the oem specs except the compression ratio which would be 8.5:1 my understanding is stock is 8:1. Would I still be able to use these pistons before I turbo and on stock tune? I’m not financially ready to turbo quote yet but I would like to drive my car around in the spring. Thank you all.
