I know that they are cable gearbox but the HRV engines are more close to eg-ek D-series engines.
For example the electronics are almost same, manifolds same 100% etc
For sure the EP civics gearboxes don't fit to 92-00 civics but for the hrv we have to confirm if does or not.
The cable shift mechanism is not so difficult to install at civics. There are many diys and project with cable issue around the web.
I looked at EPC for the mounts and they are different, but the part that contacts with the engine has same holes i think
Below are the photos of hrv and civic 92-00 gearboxes
I put them to compare and discuss the issue of fitting to 92-00 D-series engines.
