BoosteD16cx

I apologize in advance for beating a dead horse with these questions however, I've searched and I cannot seem to locate the answers I need.
MY SET UP RIGHT NOW
97 civic cx hatch
d16y7 built bottom end
vitara/eagle 75mm
stock y7 head
ebay 57 trim
converted harness to obd1 running a chipped P06 ecu tuned on chrome
o2 sensors disabled and i dont think y7s had a knock sensor

My question is this: I'm building a spare motor for the upcoming season, its a y7 block and im looking to fill it and run 75.5 mm vitaras and rc autoworks custom rods, I came across a y8 head for 40$ havent had it checked or rebuilt yet (thats in the works) to build this motor I know bolting the head on will not be an issue, I just need to know what else I'll have to buy or find to assemble this backup motor so I can just swap it in and save for wiring vtech have it be plug and play. I've searched on google and here and it seems I may need to locate a y8 intake manifold and possibly a throttle body? or will the y7 parts I already have on the car work? Also would i need to get a IACV for a y8? I also have a spare p28 that I will be chipping for the new set up.

Any help is greatly appreciated. thanks in advance.
