If the turbo engine is goodthen you shouldn't have any probs. I would swap the 77 intake(or an earlier75 intake without the EGR valve) onto the turbo motor. This way all your cold start stuff will work. You will need to put the turbo throttle body on it to get the tube from the turbo to bolt up. Use the turbo injectors on the 77 rail( for the cold start valve). You will also need to swapp out the guts from your AFM to the turbo AFM. Use the 77 distributer or a stand alone one from a 280zx. You will need to swapp the distr. shaft out from the turbo car and put a reguklar one in to run a NA distr. I think that's about it. The idea is that the ECU will run rich due to the bigger injectors, but runs lean because of the larger AFM. They basically balance out. You will probably need to adjust the AFM, but it will work. Email me if you have any other Qs.
