Default b18b1 into 99 civic cx hatch

Hello all. Im asking for info and support here. Heres my situation:

I am planning to b swap the car. I have pulled basically everything from a 99 Integra LS.

The hatch is a 1999 civic cx hatch ej6. It is a factory 5spd manual, and it is non vtec.

I have these parts:

-B18b1 engine swap (block, head, all necessary add ons beside a header)
-Ls tranny
-Ls shift linkage
-Ls obd2b ecu
-Ls engine wiring harness
-Integra trans axles
-Mounts are still on engine

Now, my question is if this is a direct plug and play. The issue I’m facing currently is if the engine will mount up correctly into the chassis. I cant seem to remember if I need to get a 99-00 em1 bracket of some sort.

Also, I do not care about anything emissions wise, my state does not do any inspections.

Thanks for the help

... aaannnddd the driver's side two bolt engine bracket to match the OE post mount and "S" bracket unless you intend to purchase an upgraded mount set. Use the engine wiring harness that is in the car... the Integra engine harness will NOT plug into the chassis, however, you may need some of the plugs from it, so don't sell it off. The ECU has an immobilizer inside, so it will NOT start the engine in your Civic. You will have to modify the ECU to delete/bypass the immobilizer if that is the path you intend. I would purchase an OBD-2B -> OBD-2A ECU adapter harness and a '96-98 Integra GS/LS/RS P75 ECU and send it.
