yeah I misread the year on your friend's civic...sorry about that...the 94 civics had the d16z6 sohc vtec don't have the b16a dohc vtec engine. basically any civic with a bseries dohc vtec engine can use a bseries b18c dohc vtec clutch in the exedy line up.
that's why I put the link up. I don't guess and listen to other people without confirmation...the fact that the website listed the part numbers was good. anyway I guess you're SOL (sh*t out of luck). Why not get an Exedy clutch anyway. They're not bad for basically a bolt-ons only motor that doesn't make a relatively huge amount of torque.
