most high comp pistons for the DE is the 10.5 to 1 ratio. However, the E pistons can bump the compression all the way to 11 to 1 (correct me if I am wrong).
10.5 to 1 will run on pump gas no problem, and getting your ECU retuned for high comp application is recommended. anything above 11:1 is unsafe for the KA (I think).
