Basically everything you need can be rather easily purchased from a Fiero vendor, or made yourself. You will have to splice the harness ( I have no gauges and it is just to the point of running the motor), custom motor mounts, adapt fittings for all your fluids (fuel lines, coolant lines, etc., and the passenger side axle has to custom made, there are tons of good guides for everything that has to be done. It only takes a TON of time and motivation, and a little bit of mechanical experience and tools.
