How complete is the turbo motor? ECM, harness, what? You'll need a fuel sender for an in tank pump, and a ignition switched circuit to run that pump, and the pump itself. A fuel injected motor has a feed and a return line, so you'll need a means for fuel to get back to the tank. If it were me, I'd try and find an intercooled motor. On the other hand, several others here have hot air cars. What's your skill set and your budget?
