I'm swapping my d16y7 into a 94 EG that has a bad d15. I will have to do a five speed swap, which I have all the parts from a donor car. Now the y7 is obd2, while the d15 is obd1, so could I swap both manifolds and use the d15 ecu and everything run right? Or do I need to change the distributor as well?

 

you would have to make the hole on the distributor longer so you can set the time but other then that the manifold should be interchangeable
