It can be done for cheap:

Some people think because they spent X, it costs X. In raw terms the motor is likely the cost the most, and depending on how skilled you are, you can probably spend 1000-1500$ to get it in and running. If you order parts out of a catalog, like your fuel system, a reworked harness etc, you'll probably have a multiple of that gone.
I spent 2500$ on my motor, 1500$ on parts to get it going, doing a custom fuel system, reworking the harness myself and so forth.
I also will spend about 3k or so in parts to upgrade it or that are related but completely optional.
