Which intake manifold fits?

Good morning,

I believe that the intake manifold from the ZC engine would fit a d15 engine- and it would 'open it up.' However i don't believe that a used zc engine would be all that easy to find. I don't believe the local junkyard would have one.

I want to put a SRI or CAI on a d15. Can anyone tell me which intake manifold i would best use? Is there one that will open up my d15 and will be easy to find?

I know i could find the intake manifold from a used d16A6 but i don't know if that would open it up as much as one from a ZC.

And yes i did search a little, however I didn't find any posts that addressed my question directly.

thanks

Any d series manifold will fit onto your engine. However if yours is the dual point fuel injection then you will have to convert it at that point.
