This is a hypothetical question for me to understand more about engine swapping, because I'm basically a noob at cars. So ignoring size what problems would I encounter with putting a dodge Hellcat Engine into a Pontiac g8 base model (v6)?
I mean its all a matter of willpower. How bad do you want the transmission to fit? Maybe a full cut down the middle and a custom transmission tunnel and a high rise hood to fit the supercharger? It all depends on how crazy you want to go...
The easiest way (in my option) is to find a wrecked but running hellcat (charger, challenger etc..) That way your will have a ton of donor parts like the wiring harness, computer, transmission, radiator, how it mounts, some fuel stuff, AC, dash cluster, etc (assuming everything fits). You will have a lot of bugs along the way and the computer will throw a ton of codes. It would take a long time but can also be a lot of fun.
It will cost you more then the car is worth.
It not the engine swap, upgrade in brakes systen etc .
But if you have the cash anything can be done
