I would talk to a mechanic about your idea, because I doubt anybody is going to be able to answer that without looking at the car.

What ever it is, it does sound like it would cost a ton of money though.

Anything is possible... with money lol. Prepare to spend Like 30-50k on that build probably even more. All that custom work isn't cheap. Literally everything is gonna need to be custom so it might even go over 100k I really don't know but i just know it's gonna be super expensive.

Is it possible? Probably
Is it worth it? Oh heck no

Money aside as I have help just wanted to know theoretically speaking}

yo can fit the engine anywhere but remember that u still need all the engine components as well
