i got a dx hatch that i want to put an ls in this will be my first swap so im a newb to it. for the questions can i use the stock ecu, wiring harness from an lx civic? also im wondering if i can use the stock integra motor mounts. im on a buget and out a car so i need the cheapest possible way to do the swap. thanks in advance

 

If you can find a OBD1 LS engine, everything should work with your harness.
And you will need integra mounts. You will need the LS ecu as well.
