engine selection pending Nitro

I want nitrous thinking of either a 50 or 75 shot.but dont know if i should run it on a b16 0r a b20 or perhaps a b18b.I want to choose the engine acccording to which engine will take the nitrous most safely.Also what would be the faster of the 3 with nitrous (compeletly stock except for I/H/E & A chipped ecu,Slightly Tuned) ? Basically Which is got most potential,Stock with Nitro.will the nitrous make up for the lack of torque on b16.

search…that’s a vague question. if you can’t find the answer here, look on H-T. we have no clue what your going to do with the engine…headers, intake maifold, cams…stuff like that. the most useful scenario would be the B16 as it has more top end…but I am not a nitrous guru.
