compression ratio on stock internals?
i have to replace the piston rings and valve seats, so i'm gonna go ahead and replace the pistons to bump up the compression ratio. 11.3:1 would be had using USDM B16 pistons, whereas i could spend more money and get 10.8:1 with USDM B18C5 pistons. question is, is 11.3:1 too high to run daily? i know the timing will have to be turned back to stock, plus i already run 93 octane anyway. any downsides to this? any input would be appreciated.

anything from 11.1 to 12.1 CR is fine to run daily on 93 octane
