i have an h22a in my accord out of a 93 usdm prelude. it has CAI/H/CBE test pipe, underdrive pulleys, 70mm throttle body, skunk2 racing intake manifold, no balance shafts, 310cc injectors, walboro fuel pump. I was going to turbo it but then i bought an s2000 so i just put nitrous on it. i have been running a Nitrous express wet kit for about a month now and i was thinking about going from a 50 to a 100. But im not sure how that engine would handle it. No one around here even has nitrous on preludes and i talked to one dude who blew his up on a 75 but his was an f22a prelude and he was using a zex dry kit. Which makes me extreamly careful about how much i want to push through mine, also thats why i only put a 50 on it. Also i have the nitrous nozzle five inches away from the throttle body but someone said it needed to be by the filter for better fuel atomazation(or however you spell that). My filter is by the ground so should it put it mid pipe or at the bottom of the cold air intake. Anyone here have any experince with nitrous on h22a's?
