ITRsedan

I just recently bought a 2000 Honda Civic EX for $500. The motor wasn't running and the body was not in good shape. It was a real good deal. So I bought a JDM D15B obd1 motor. I got a couple questions if any one can help me.

First, I took the old motor out. Now before I put the new motor in, I want to know what I need to do in order to put this new OBD1 motor in the car. I changed the dizzy and fuel injectors so far. I tried changing the alternator but the pulley on the old obd2 alternator is a lot bigger than the pulley on the obd1 alternator. So the belt won't fit. I tried changing the pulleys but they don't fit on each other. Do I just need to buy another belt that fits?

Also the OBD2 engine wire harness has extra sensors when installing on the OBD1 engine. Many of them are on the Intake manifold. Do I need to exchange intake manifolds? Will it bolt right on?

I think these are the two main problems I am having. Is there anything I should do? Please let me know. Much appreciated. Thanks.
