ok i have a dohc zc wether its 1st or 2nd gen iunno thats what im trying to find out ok it does not have pgm-fi on the intake and there is an extra sensor on the intake on the back of the no.1 cyl intake runner and what is the firing order im asking these questions because there is like 4 diff kinds of zc,s the car has no characteristics of a usdm hatch and its stamped honda of canada all over it but the motor is just stamped zc like all the others o yea and it has one more vac line coming out of the back of the intake if anyone could help solve this problem of mine please any advice or thoughts will be helpful

 

DOHC ZC firing order is 1-3-4-2 and wires go like this

 

this is 1st gen DOHC ZC:



this is 2nd gen DOHC ZC:



this is 3rd gen DOHC ZC:

 

jlicrx: whats the difference between the 2nd and 3rd gen?

 

OBD0 and OBD1 - 3rd has CYL sensor in the distributor, MAP on throttle body, different intake manifold which will accept the later and larger TBs, cooling fan switch on the thermostat housing, 4 rib crank pulley - that is about it - internally they are the same

 

thanks

 

jili im going obd 1 on my obdo zc and need to know will a b series cam bore plug fit the opening where the cyl sensor once was??

do the obd1 ZCs produce more power then the obd0s?
