hey i got a 96 coupe with a d 16 but i want to do a head swap but what are my options? i dont want to change my harness. any ideas thanks

 

just the vtec heads from a d16y8 or d16z6.

 

ok so i cant do any dohc heads?

 

The D-series is almost entirely SOHC heads. The one exception is the ZC, which came in 2 or 3 flavors, one of which was a DOHC. That engine was from the late 80's/early 90's (~88-92).

The B series and H series have DOHC heads, and different series blocks/heads aren't compatible with each other, as far as I know.

Now...reading the specs on the ZC DOHC on wikipedia, the bore is the same size as your d16. Maaaaaaaaybe that would fit on a d16 block. There are other things to take into consideration...off the top of my head, I can think of the head-bolt holes and the approximate camshaft sizes. I know the DOHC ZC was made in the late 80's and your engine in the mid-late 90's, so chances are that the combustion chambers are very different. That alone would make me think that the stock ECU tuning wouldn't be compatible with the DOHC ZC head. Assuming this head bolted on and you could turn the crankshaft through a full cycle without the valves hitting the piston, then the ECU would probably still have to be tuned to work with this engine optimally.

I searched 'dohc zc' on google and the first link mentions that the DOHC ZC is a JDM only engine. SO....assuming that you can swap a DOHC ZC onto your d16, given what I said earlier, you'd have to get a DOHC ZC head, still. That'd either be JDM or a very very rare find in America. To answer your question: maybe it's possible, but for the effort and gains, a B series swap would probably be easier. It'd require less parts-hunting, less research because they're well documented, and because B-series supply is so high locally, it might be cheaper, too.
