ok i know this a noob kind-a question but i have to know.


wats the highest compression i can go on 93 octane
my brother says its 10.5:1
my build so far is a stock b18a bottem end ecept for jdm itr pistons (11:1), crower street or strip cam w/ crower dual valve springs and crower valves
wat compression am i set at currently

thanks,
Clay

 

some go 12:1 or maybe even higher like 13:1 tuning is the key...

 

i found a set of os ctr pistons for real cheap, if i mate them to my ls rods w a mild cam am i going to have any problems. (piston to head clearance,to high copm. for 93 oct, etc)
and can i still mill the head w/ ctr's
