Instead of moding my v-6, ive been thinking about maybe doing an engine swap. There aint much that can be done to the 3.8. 400 hp is the most ive ever heard one reach. I dont know much about engine swaps, but I was wondering if instead of getting a GT 4.6, I could maybe get like a Supra engine! I know its a stupid question, but it makes sense. Those things come with like 350 hp stock and can be modded to over 900 hp. If it is possible, about how much would it cost to do it?
