i have a 99 dx hatch with a d16y7 motor and im planning to put a d16y8 head and tranny. All i was wondering is should i stick with a head from a 99-00 or would it matter if i got a 96-98 head cosidering its obd2a? and would i run into any problems? any help would be great..thanks in advance

The only thing that really matters in terms of obd is the ecu.

so i could get a 96-98 ex head and use the 99-00 p2p ecu?

would anything change if i use a 96-98 ex ecu other then my car changing to obd2a?

Your stock engine harness won't plug into the ecu and function correctly.

i have a ex wiring harness will it still not function?

Depends on what year the ex harness is from, 96-98 or 99-00. I'm also not sure about which other plugs on the harness is different when obd is question.

so aslong as i have the year of the ecu and harness the same everything should be ok right? and the year of the d16y8 head doesnt matter?
