F20 is also a unicorn and shares the same mounting patterns of H22 - meaning it will require a massive amount of cut and weld.
This accord is very unique in build - It was Honda's first attempt into their "modified strut" suspension setup and the car was built around the suspension, It shared very little design with later civic and integra platforms.
If you are hellbent on an accord, buy a 4th gen like a 1991 model and install an F20A in it (its not that rare) - it fits bolt to bolt, or install an H22A - which also bolts on.
The 3rd gen accord is very old and a unicorn car to start doing such swaps. They never work.
To understand it, open the bonnet, and inspect the gearbox, it seems that it not held by any mount at all, The entire engine and transmission assembly is supported by 2 big load bearing mounts on the bottom subframe members and one timing side mount, there are two torque mounts that stop rotation (pendulum) action of the engine - one is the big dogbone on top going to firewall and one is a small rectangle mount under the transmission bellhousing.
