crossmember is notched down to where the folded cut up section ends, theres a bit of a profile line along the from of the crossmember, i just followed that
as for the sump you need a bluebird ones im pretty sure, as they are the closest to the engine, then you will have to modify it from there. pretty sure i didnt have to do a whole heap of cutting to get unfams sump how i wanted it
tunnel, you can get away with a stock one if you just want then engine physically in the car. if you want to do it well and give enough room for anything around the box then i'd go a new tunnel. 120y ones work pretty well, stanza, 180b, 200b are all pretty similar but need a bit more work to make fit.
you'll also most likely need to move the handbrake back a bit with the bluebird box
with this crossmember and sump i got an L20b to clear the bonnet with the standard airbox
