I have a wrecked 2005 Mazda6 with ~93k miles on it, engine and transmission still work fine.

Here's my question: would I be able to swap the engine in mine into a 2004 with a 3.0 MZI V6 and manual transmission? Does the transmission type matter?
 
Being that you have the donor car there, you could do the swap. But its not just a motor swap. Were talking the entire engine and maybe even dash harness, engine, trans, all the mounts, everything will have to be swapped. As nothing is shared between the two. It would be a pretty big job to tackle. But like i said, since you have the full donor car, it would be possible. If it wasnt for that, id say flat out NO.
