what don't i know? according to ClubCivic.com - Honda Engine Codes & Specs '73-'05 the 1.5l hondas made anywhere from 70-102 hp, one exception is the jdm 130hp. And the 1.8l made anywhere from 130-170hp

now lets say u add boost, going on 8hp per psi, u boost the 1.5l (ill be generous and say 90hp to start with) and u add 8lbs of boost u make about 154hp

so why not swap in a bigger engine and boost later or add nitrous
