The crossmember is pretty easy to get at...with the motor out.
$6100 for a fully build ITB D16.

I dunno how to get crap smogged in cali. Check out the various sites online to see what their prices on swaps are. One thing you should keep in mind is that the GSR transmission has a hydraulic clutch and your car has a cable clutch pedal. You can get a cable B16 swap for like $1200.
