looking into getting some pistons and sleeving my block(golden eagle) i was looking at 9:1 CP forged pistons and some aftermarket I beam rods(not sure what ones yet), but with a GSR head what would that bring my compression to ? bc i kno the compression ratio changes when u put another head on the b20 block. so where would i stand with 9:1 pistons in the b20 bottom end and a gsr head.Any input would be helpful. TIA

 

I pretty much just wanna stay in the 9:1 cr range 9.5:1 is probobly the highest ill go...if the pistons i said before wont give me the wanted cr,what pistons would? I know sum ppl around my area doing high compression turbo(seems to be the thing to do last season) with 10.5:1 pistons and plenty of boost ofcourse on a sleeved block(b20,gsr,and b16) all with aftermarket forged pistons that were high compression and they used them for a turbo setup(one guy had a gt39r think he made like450-whp)
I jus need help picking out the rite pistons for my build.
