and to let you know, most nitrous systems are setup so that they activate at wide open throttle, not by pushing a button. and nitrous is the easiest way to get 120hp. you don't want nitrous though, so for 120HP get turbo and an engine build.
if you mean not a 120hp gain but rather to get up to 120hp, the easiest way to do this is a mini-me swap. that is putting a d16z6 head on your d15b7 block, and using a d16z6 ECU.
Well what I was wanting was to have a good clean reliable car to drive that still got good mpg with a little more horses cuz the thing is slow as hell.

from your original post, are you trying to get to 120hp, or trying to gain 120hp?
do the headswap, but use the 96-00 head, from a d16y8, along with the intake manifold, then do a good intake and exhaust, and youll be around 130-135 at the flywheel. not fast, but a lot quicker.
