K20z3 vs k24a2 (idk if this post is too specific for this /r I apologize in advance)

So I currently have a 05 auto base rsx k20a3 and was looking to engine + manual trans swap it soon but I'm itching my brain between k20z3 and k24a2

I did some research and apparently they don't have the same engine mounts but some say it does....

So I'm trying to see if anyone know which one would be easier and cheaper to do (including buying the engine and trans) cuz I know there's more power to make on k24 but if we talking about 1k difference it's not that much but if it's a remarkable difference I'll pick the cheaper one

Honestly my main main concern is more about which one could be done easier, cheaper and faster for a teenager who's gonna do all that in his parents driveway and still goes to school lol

Thanks !:)

Ps: if you have a ytb link or something of someone who explains it all you can just paste it
