Not a great idea. Buying junkyard parts for 240k for jugaar installation gives you a much greater chance of spending more time fixing more problems, usually electrical ones.
There are also no laws here, so if you end up with an even bigger nightmare for a car, there is nothing you can do.
Your existing engine can be overhauled, a new clutch fitted, and your gearbox fixed or replaced if necessary. I'd recommend finding a competent mechanic.
