im running hondata s300
msd digital 6
pro race fogger/direct port NOS of course
i have an arming switch, activates my full throttle switch, switch does not get power until i hit 3200rpm. spray comes in at 3200rpm and drops off at 8200rpm, motor revs to 9000, that way you can't over rev on spray (not good) get some slightly bigger injectors and i belive even s100 has a built in nitrous controller. alot of ppl don't like spray, in the end it's cheap, more reliable/dependable than any turbo set up and makes just as much power.
this is for an s2000...hondata s100 or s200 doesn't work for that application.

there is a k-pro for the s2000 now. it wouldn't be a bad idea to get it. i don't know of any nitrous kits that can retard timing on a coil-on-plug car.
