for those ep lovers going for boost and want a little bit lower comp ratio JE pistons offers a 9.0:1 setup for the rsx-s. the bore and stroke are the same as the si. [displacement] (although some milling will probably be required anyway) i'm pretty sure we could use the same application pistons as the rsx-s be it higher or lower compression.

what are the gear heads' thoughts on this? :)
