well i have been seriously looking into building a motor to run some heavy nitrous on.
right now i have a JDM B18CR, with intake, header, exhaust, clutch and flywheel.
now i was thinking of running something like a 120 shot of direct port nitrous on this motor.
my question is should i sleeve it or worry at all about the crank when building the motor to handle that amount of nitrous safely? and would hondata be able to tune this properly, or should i get a standalone like aem ems?
i know for sure that im going to get aftermarket pistons, rods, bearing, vavles, ignition **** and maybe an oil cooler.
any tips to help build it properly is appreciated.
thanks

Stock sleeves and crank should be fine. Hondata can be used to tune nitrous however it doesn't have an entire map that you can tune for fuel and timing. It only allows one input for while on the bottle. Also, an oil cooler isn't really necessary for a nitrous setup. I'd consider it more necessary on a turbo setup where the turbo is oil cooled.

thanks for the info RyanCivic2000
i wasnt sure if hondata would be enough, would it still be ok if i ran C16 when using nitrous and tuned it with hondata? if not i guess ill just get a standalone
and i was told by a couple peope i should be worried about the head, if im spraying that much?
i was thinking of bumping the compression to 12.0/1 would that be too much compression?
or should i just leave it at around 11/1?
any suggestions?

the head really isn't effected by the nitrous. Well valves maybe, but they would only melt/burn as a result of bad tuning.
