What kind of headaches can I expect while attempting this swap. Both are manuals.
Will I have to locate a 2000 EX ECU? and will I need an adapter? or can I use an adapter of some kind to reuse the origional one?
I presume that I should use the '96 wiring harness, distributer and related sensors.
Any difference in performance between the two?

 

So your car is a 96 and your using the 00 motor? Use the 96 distributor and your original harness for the 96. Idk what else needs changed other than you need a jumper harness from obd2b to obd2a.

 

What will the jumper enable me to connect?

 

Your 00 ecu. Although you could more than likely still use your 96 ecu since same motor. The 00 one is just a newer obd and looks for more sensors. I was assuming that you were switching ecu's as well.

 

Thanks for the quick reply Marvin,
This all makes perfect sense. I can simply make the 00 D16Y8 resemble a 1996, so the '96 ECU should never know what happened.
I presume that the '96 harness will plug into the 2000 crank trigger as well as the injectors and other related stuff?
I have installed several Civic engines, but have felt uneasy because Car-Part.com interchange lists the '99 and 2000 engines seperate from the 96 thru '98.
I wonder what the difference is?

 

Everything's the same, same sensor and all. The only differences I know of is that the 99-00 uses an air injection system but its mechanical and won't affect the ecu. And distributor plugs are different so just reuse yours. Also the 99-00 exhaust manifold is better as well on the 99-00 Y8. This is assuming the 99-00 your getting is a manual or auto engine, is your current engine auto or stick?

 

Manual to manual, I will have to reuse my old exhaust manifold though, it was not included in the engine purchase.

 

only difference is OBD2A (96-98) OBD2B (99-00) use your 96 distributor. everything else will plug right up.

 

Use your 96 distributor, 96 engine harness, and 96 ECU.

 

I am curious why your doing this swap? Just need a newer motor? Less miles?

 

I assume the motor will have the intake manifold right?

 

if the car is running a 96 ecu u must use the old 96-y8 ecu because the newer intake manifold have air injection and this ill create a vacuum leak.

 

question i have a 96 ek hatch when i got it it had a 98 y8 in it but had to sell my motor. Just got a 00 y8 out of a auto ek coupe what intake manifold do i need to get it running right
