i think the leak is coming from a host, but it's hard to tell because it's
behind the engine, and i can't quite see where it's leaking from. unlikely
it's the rad.. like i said, it's new, and i can't visibly see anything
leaking from that area.

i checked out the jdm zc's.. the price is "okay", for a new one (~$1000
american, plus shipping). what are the chances of me finding a used one,
out of a wrecked car? is it a popular engine? what did it come out of?
what work is involved in converting the wiring to MPFI? would i need to
get an ecu for it, or any other parts?
any other suggestions of engines that will easily fit?

well, thanks very much for your help so far, fiero-chris. speaking of
which, i was very close to buying a fiero..
