the head should bolt up to the block (only the d16a8/9 from the 86-89 integras and the jdm dohc zc models heads would not match up with the normal d series blocks such as the d16a or d15b)

as for wiring i'd have to look at the cylinder head from the d16y7 as i'm not sure if you can use that head on your engine...if you got another obd2 manifold you are looking at very hard wiring and the req't of using an ecu for that model head/manifold...if you are trying to swap on an older crx si manifold and just do a simple wiring & si ecu conversion it maybe possible

i don't know these off hand b/c i never did a mini-me or swapped heads on engines (did just engine swaps)...i'd have to see it with my own eyes and compare the oil pressure switch and the manifold to see if you can get around it
