Civic EG

ok i have a h23a in my civic 92 si i have a zex nos kit i want to know what would be safe ass to not blow my engine how high could i go with a 50 or 75 shot help would be apriciated thanks

Zex recommends a fuel pump upgrade for the 75 shot, and probably a regulator wouldn't hurt either, with that being said the 75 would not hurt a thing...... if you have the fuel pump I sprayed a buddys b16 on a 65 hit with no mods just a chipped ecu and it ran great.


Oh it would help if you told weather it was a wet or dry kit, my advice was based on it being a dry kit

its a dry kit thanks fore the info
