dude.. we need more info.. as in what kind of civic it is... because VX has VTEC ... but its completely useless because its a 1.5 L VTEC-E (economy) and the EX and SI have a d16z6 .. 1.6L VTEC which is bad ass ... good motor.. but u should go for a swap .. to like a b18b1 or b16a2 .... both good engines and theyre DOHC... but b1 is nonVTEC.... anyways... find out if u can swap it
