8.4 or 9.4????
 

ok so im slapping together a new block because i kinda made mine die. and i have two options. here it is
its a d16 and ,thats all it says, but the block says p28 and the pistons also say p28 so im going with d16z6 on the compression calculator and i will have a d15 head on it. with the p28 pistons i will have like 8.4 cpr and with the pm6 i will have like 9.4? so which should i go wth. i know that with the lower compression it would be a little safer to run boost but it will be real slugish out the hole. any advice would be appreciated im kind lost and dont have the experience with driving cars with diff cpr. thanks again

a 9.4 c/r would be pretty ideal... tunning would be safe, and it would still have a little more power when not in boost.
