Yep. I liked the feel of a torquey DOHC, it just feels like it wants to move a little more. Even my stock D16Y8 feels like it doesn't want to get out of it's own way.. I wouldn't put i/h/e on it unless I got the parts free, but that's my $0.02.intake header and exhaust will net you maybe 5hp and cost somewhere around $1000
I think i would rather spend 1200-1500 on a b18b1 motor and keep it stock than to put i/h/e on a D series.
Are you retro fitting projectors in those headlights, or just slapping some HIDs in them, or just some nice halogens? I think I'm going to grab a pair, since I can get them for almost nothing, and maybe retrofit a set of projectors in them.
