ok, so it took about a yr to notice, but when i bought the car i rle didnt kno much about tuning, the other day i was puttin in a new clutch and noticed that i have a d16z6 in my 96 ex. i am pretty sure its sposed to be a d16y8 in my car lol and that the z6 is from the 92-95 si's. neways the clutch i ordered was for a y8 and bolted in fine. is their any possible advantages to this motor in my car/could the tranny be original/ do you think the ecu/harness is diff than stock because i think the z6 is obd1, and the y8 is obd2. not sure about the whole situation any input would be greatly appreciated. o and the car runs great and redlines at about 7500.

 

Nothing wrong with that, the Z6 is pretty much the same motor. I'm sure that some previous owner blew the motor, then some shop came in and swapped this motor in and put the Y8 intake/exhaust manifold onto it. The Z6 has lower compression and slightly less hp though. I'm sure the tranny is the same unless your car is a theft recovery.
