Planning on swapping in a B18C1 engine into my 90 Civic EX and wanted to double check all of the parts that I'd need. I'm also converting the car from auto to manual transmission at the same time. This will be my first time doing any work on a car so please excuse by noob-iness, but I really need things spelled out clearly since I have no experience and don't know what to assume. All of the How-To's I've read are very helpful as to the process, but a bit vague on the parts required.

Parts:
B18C1 Engine
Y1 Transmission (so that I don't have to convert to hydraulic tranny)
P72 ECU
Hasport Motor Mount Kit
EF SiR Shift Linkage or modified 90-93 Integra Shift Linkage
EF SiR Axles or 90-93 Integra Axles w/o dust rings
90-93 Integra Throttle Cable
OBD0 - OBD1 Hasport Adapter Harness
OBD1 Distributor
4 Wire Primary Oxygen Sensor
EF Civic LX/EX Manual Pedal Cluster

However, while looking at https://honda-tech.com/forums/honda-crx-ef-civic-1988-1991-3/faq-my-swap-parts-list-b18c-s2-im-into-91-crx-dx-953089/ it seems I'm going to need a whole bunch of other stuff like bolts and vacuum lines? What of that do I actually need?

Also, what exactly do I have to do with the engine harness to have that work? And will I have to do anything to keep AC/Power Steering?

Lastly, I'm seeing in complete engine and tranny swap packages from JDM importers, alternators, starters, distributors, flywheels, engine harness, etc all included. If I just pick up an engine from someone off craigslist, what should I expect to additionally need/what would they include with their general listing of "X engine for sale"?
