Is it possiable to change my automatic 93 honda civic, which is automatic to a manual? And if so is it really hard to do so?

Here are only some of the things you will need to get: manual transmission, shift linkage, pedal assembly and ECU.

After you get all that, then there's a process of putting it all in.

There are a lot of informations on this on the internet. Just do a Google search.

By the way, I'm not trying to discourage you. If you have a lot of time, a nice place to work, and are willing to do it, I say go for it. Just research what you need, and go do it. You wouldn't be the first one who did it.

I have done 3 times there's a lot more to it then you might think here's what you will need manual transmission, shift linkage,shifter(with bushings) pedal assembly,ECU.flywheel clutch(all the assembly)clutch slave cylinder clutch master cylinder and all hydro lines to run the slave cylinder also you can run the auto ecu but you will have a CEL (check engine light)cuzz if you have a an ex (vtec)civic you will need the p28 ecu and they are very expensive
