I'm not going to say it is impossible cause anything is possible if you have enough money to do it. But realistically it would it will be a total nightmare to redesign the engine compartment with proper mounts, electronics, transmission, not mention the cooling system, exhaust, power steering if you still wanted it. I have heard of rigs that were modded to take a custom made engine cradle that carried the complete power train with all the control system in one unit, but I have never seen one to have any idea on what was done or how to do it. Some things just aren't practical.


What you need for that to happen is tens of thousands of dollars and probably a couple of years. An '04 GP with those kinds of mods will still never really be worth anything regardless of how well you do it, so consider that money flushed away. If you're rich and are just doing it for the fun of it, knock yourself out.
