from my honda experiences it seem that both in general and specifically with 
hondas ( due to excelent cumbustion chamber design) that these engines 
tolerate a bit more cylinder pressure. id be willing to bet with a small 
reduction in spark and some carefull fuel mods that you street goal of 9:1 
with 93 octane is doable. however i do strongly advise that it would be ideal 
to go ahead and pull about 4-5 degress from the higher boost regions of the 
sprak map and work your way back up. this might seem extreme but the last 
time i checked honda pistons were a bit priceys. anyways if youd like to talk 
more email me offlist. no need for heated discusions. im running a 1227749 on 
a honda using gm parts. so i do have a bit of time as well as using piggy 
backs and boost retards with an older version on my 86 accord. email me we 
can talk at great length.
