im still looking for an replacement for my crx now im looking at a dohc zc but someone from an auto parts store told me that jdm engines are good but harder to get parts for is this true and if i do get a zc can my sohc d16 4-2-1 header bolt on to the zc

 

if you were to get a dohc zc yes parts are harder to find but you just gotta look in the right places. and yes you could use a sohc 4-2-1 header just make sure you bore is out a little to fit the dohc.

 

i hear that zcs wont pass emisions is this true

 

In Cali, true. But I've heard that if you swap over parts from the early integra's you can pass visual? Search it up, too lazy.
