whoa here! high C/R and N2O DP = wrong direction.
damn, what was i thinking all this time.
i'm currently running 11:1 comp. with 125 shot DP.
same kit you are speaking of, NOS #02040 direct port for B18C1.
one step colder plugs with ignition retard. runs great with ignition units, FPR, Fuel pump and stock ECU. 93 octane also.
if you build up the internals, pistons/rods/rings/valves/hardware, you'll be fine with some basic tuning and precautions. as roby mentioned i wouldn't go much above 11:1 without some good tuning. i'm going Hondata soon so i can fine tune it and be safe.
if you want to run stock that's ok too, just jet it at 75 instead of 100 or 125 so the motor lasts awhile. just follow the rules and you'll be fine.
