I'm pulling my pristine D16y5 from my '96 HX (100k miles) and putting in my wife's EG, with a tired out 220k mile D16Z6. I'm gonna swap a B18b1 into my EK, so yeah.

I plan to put a new clutch and timing belt/water pump on the Y5 as well as the Z6 trans and exhaust manifold since the Y5 pieces blow hard.
So my dilemma begins here...

I bolt in the Y5 motor with the OBD1 Z6 harness on it (right?)

Or do I use the OBD2 harness? With a jumper or something for the ECU?


I haven't swapped a motor in years and even then it was OBD1 only.

I may have this totally wrong, but thats why I'm posting. I tried to search for OBD2 motors in OBD1 chassis, but I just got a lot of threads for the reverse scenario.

Any help would be much appreciated.

 

Word.

 

Bump

 

Unfortunately I don't know a whole lot about swapping a newer engine into a 5th gen Civic, but hopefully a bump will help you out.
