If you don't have a hoist, look into a chain hoist. I have one, and while not as convenient as an actual engine hoist, it will work, is substantially cheaper, and doesn't take up as much room while using it. The only downside is you can't use it if the ceiling in your garage is finished. I use 2 4X4's to spread the load across 4 ceiling joists and run a chain around them to hang the chain hoist from.
