yeah dude, you definitely need the support... otherwise it just doesn't work... I've seen a 92-95 hatch go to an integra and it wasn't hard at all... done in 1-2 days. The hood matched right up and everything... the hardest part is the fenders, obviously... I think the guy I know ended up using half civic, half integra fenders and welded some shit together... but yea its not too bad, good luck!
