if all you'r tryin to do is get it running so you know if it's good or not, you don't need the s13 speed sensor or cluster. in fact, you might be able to swap the speed gear in the tail of the tranny from the dat to the ca tranny and use the stock dat speedo cable. and since the car is so old you shouldn't have emissions on it so you don't even need the carbon can.
belts off an 88 Pulsar SE(thats the only one that got the cade). it's got coil packs so you don't need to do wires. and build an intake out of black sewer pipe and cuplers from Home Depot. works fine as temporary stuff, my friends and i do it all the time with engine swaps.
if you find an s13 tank, the stock pump(if its in it) will be fine till you mod the engine.
