I bought a 94 civic recently that came with a D16z6 full engine working, the only issue is I feel the bottom end is weak. I have an extra D16z6 head on hand that I can slap onto a block and drop in while I'm getting the current rebuilt but im not sure what blocks will fit the D16z6 head without modification or having to dig into the wire harness. Any suggestions?

 

Suggest listing what blocks you have, then we can tell you if they will fit.

 

Will fit? I believe all D16 single cam blocks.
Edit - dseries.org is a great resource for D engines.

 

The reason I was inquiring was to make sure I didn't purchase the wrong block beforehand sir.

 

Thanks for the link man.
