What is the actual effective comp. ratio of a stock ls/vtec?
I need to know what the compression ratio of a stock ls/vtec is bc Im wondering what pistons to order to avoid too much of a comp. ratio, its going to be N/A all the way and whether or not I should get my block sleeved, Im looking for a comp. ratio in the 12 range.

stock its 9.5:1 with a b16 or itr head and 9.5:1 with the gsr head.
with p30 pistons you will be at 11.8:1 bone stock
with jdm itr pistons 11.5:1
and ctr pistons 12.2:1
