I am looking for an inexpensive way to boost my little honda's power with out spending to much money. And I figured that swapping on a better head is just what I need, I wanted to use a DOHC head (D16A9/Z5) because I was told you can tune those a little bit more power from those then a SOHC head. But I am not sure if the head will bolt on to my D15B2 block without modification, like if I have to tap the block so that head can bolt on properly. And I already know that I should get a new ECU, upgrade from DPFI to MPFI, which would mean a new intake manifold. I'll be doing thins on my 1990 Civic Wagon.

I been posting this question on all the credable Honda forums, better to get more information from as many places as possible.

the DOHC head will not bolt to the SOHC block

Was any incarnation of the D16 a dual cam design?

The D16A1 is DOHC, and that was used in the 1st gen Integra's. So I figured the D16A1 head should bolt on to the D15B2 block with little difficulty, because they are both of the D-series, and you would assume that they would try to keep the number of different engine blocks to a minimum to keep production costs down. And going from that, I would think the only difference is where the hole for the bolts are located, but I could be wrong. So before I buy the D16A1 head, I am going to take a head gasket from a D16A1 and see how it lines up with a D15B2 block, and then make my dicision from there.

I found out through hondacivicwagon.com, that I can use a DOHC head from a D16A8 with out any modifications to the engine block. To bad none of those where brought over here to the States.
