Okay what's the differences betweeen the d16z6 and the d16y8. I mean i know d16z6 is obd1 and d16y8 is obd2 but what makes them different and which is better?

Oh, and if I were to drop a d16y8 into a EG coupe, what all would I have to do to the d16y8? Or is it drop it in, plug and play? Might be doing a d16y8 swap into an EG coupe so I was just wondering.
