i was going to drop a y8 into my 1994 civic HB and i was wondering does it plug all in and which ecu should i use?

 

The Y8 is OBD-II, so you'll either have to convert it to OBD-I or convert your car to OBD-II. The Y8 also has a knock sensor, whereas the Z6 does not. You'll also have to change out the upper driver side mount, since the Y8 mount is different fromt he Z6 mount.

 

you should be able to use the wire harness of the hatch and just add the vtec plugs to it...not a very hard swap i helped my buddy do his in 9 hours total....

 

you also would need a p28 ecu for this setup...i have one if you need it...
