I have a friend that has nitrous in his SE-R altima with a hundred shot, he went thru 2 engines before finally building one with forged pistons. The #5 piston would always crack its upper ringlands on the piston. If I recall correctly he had it set for 100-110 shot, wet setup. After he put the third engine in he went to a 125 but made it direct port with throttle linked actuation for the lower gears like what the O.P. is talking about doing.
