Hi Ed here
I have a 90 Civic si 1.6 and am thinking about putting in a ZC .
I'm on a tight budget. Firstly is it worth it? What has to be adapted ? Is this a SOHC . Is there a reliable source out there for a low mileage engine?
I'll do the swap myself.
thanks.

from what i understand its very straight forward, either the sohc or dohc i believe its all the same...

yes its worth it and there is sohc zc's and dohc zc's.......the better of the two is the dohc, its pretty much a straight swap and u can use whatever tranny you've got now with it but id reccomend trying to find a lsd zc tranny with it

for your si it is a striaght drop affair...if your motor is fine then I'd jsut keep it cause the sohc zc is pretty much the same motor. But if your looking for a lower milage replacement then that is ok, but the dohc zc has more hp..130 hp to be exact..both are direct oem replacement procedure

single zc is way quicker than a normal Si d16a6...my single zc ran high 15's easy and with ****ty broken mounts and old street tires...now I have a junky d16a6 and it blows goats...but of course the double z is an awesome 1 day drop in motor

zc into an si is so simple, direct bolt in and you have to extend two wires to the cam sensor. turn key and enjoy
