its in a 90 civic hatch so weight is pretty good. and im looking for 12's with nitrous. i would hope for somewhere in the 13's without spraying. i ran a 14.155 with the motor completely stock and only launching at 2500 rpms. i'd like to cut 1.5 off of that. does this sound like a good way? how do i know if the valves have a heat coating? a pretty well known machine shop would be doing the port and polish job. how serious of a port job do i need for the setup i am looking at? it looks like a good cam for me would be skunk2 stage2 cams. but will they be serious enough for my goals?
