the thing about the d16a1 ecu is that it has a higher rev limiter, so if you can't find the jdm zc ecu, you'll prolly have to get the d16a1 ecu, it'll prolly be way easier to source and a lot cheaper newayz
i've yet to find a rebuild kit, kinda sucks, if ya find nething, let me know!!!!!
are you sure you got the ZC valve cover, cuz the d16a1 won't work
