I have a 97 CX Hatchback with the D16Y7 non-vtec engine. I was planning on going with a NA build with high compression. I was wondering if I should go with this engine or a SOHC Vtec D16? Or if its possible, can I just swap the head of a SOHC Vtec D16 into the D16Y7 I have? Would it be just better if i just swap the whole engine? How much would it cost?
