You could always do the fabled AWD conversion. Then you'd be FWD AND RWD. I personally would love to build an S13 fastback, or a Z, preferably Z32, but Z31 is cool too. It makes me sad that as cool as my B13 may ever be, I can never slide the tailend without the e-brake.
That being said, you'll regret selling your B13 the moment you sign the title over. You've put so much effort into that car for so long and you're not even done (even though your current power is obscene as it is). Start on an S13 if you want, but don't get rid of your Sentra. I've only had my B13 6 mo and it's been a pain in the ass, but I don't think I'll ever get rid of it, I love it too much already.
