The D16 isn't any better, hardly notice the difference I'd think.
DOHC D16 is nicer to drive because it's less gutless down low, but I seriously think you're better off with the B18B2 or B18C2. If you buy a Civic make sure you buy one with a conversion already done lol.
is there much difference with the b18b2 and b18c2? have u ever like test drive both of them?? because i never had the chance to since one of my mates do own a gsi teg but its an auto and he is a stingy bastard and wouldnt let me take it for a spin. -.-
