I just bought a '91 CRX that has a D16A swapped into it.
​​​​​​ From what I could find, this is a JDM engine.
I read somewhere that D16Z6 is pretty much the same.
Obviously, I'd like to maintain the engine over time: oil change, plugs and wires, etc...
Any advice???

 

Edited my post

This is a d16y8/d16a(96-00 civic ex), the d16z6 is similar but with different intake and found in 92-95 civic ex.
They also go by "zc sohc" and model year. Example: 92-95 sohc zc, 96-00 sohc zc, and 88-91 sohc zc non vtec

 

Sounds good. Thanks for the advice! Should be a fun project overall.

 

96-2000 EX is a D16Y8

 

From what I have found, the engine is JDM, from a civic derivative they made there.
​​​​​​ But I've read that it should be compatible with parts from 92-95 Civic ex/si.
i just wanna be sure of that.

 

Yes, the D16Z6 was the standard engine for the 92-95 ex/si Civic. Assuming you have the engine pictured, it's the same head and a very similar block to a Z6, with an intake setup more like the 96-00 D16Y8.
