Engine swap

Yes, but I wouldn't. You're going to need everything in the powertrain; transmission, drive shaft, motor mounts, transmission mounts, computer, the wiring harness. And don't forget the suspension, rotors spindles, brakes, rims, and shocks. Then there is the cooling system, the electrical system, the power steering. You see where this is going? You will increase the power to weight ratio. The parts used in a lower horse power vehicle don't have the same strength requirements so the manufacture cuts cost by not using them. They are still good quality parts (in most cases) but only meet the requirements of the lower powered vehicle. Find a Junk Yard donor vehicle and strip the parts off of it but it may be more trouble than its worth. I did it with a 64 Ford Falcon (which Ford used for the first Ford Mustang). The motor mounts on the frame came from a Cougar, the engine from a Mustang, 289 CID, and the radiator as well. The suspension came from a Maverick. I blew up the 250 that was in it so... you get it. Good Luck and I hope this helps in your decision.
