i have a 93 dodge daytona es 3.0l 181cu v6 and well it is giving me so many problems that i'd have to rebuild it or drop a new one in it but that would cost more than it is worth and i was wondering if i could drop the 4 cylinder turbo motor into it without changing to much. and i want to know what i would have to change if i put a different motor in it like electronics.

I am not sure, but I don't think the engine mount points are the same. If you really want to do this you will want to find a doner car and swap everything under the hood including the transmission and axles as they aren't interchangeable between the 3.0L and the 2.2L and 2.5L.
