The 318is got a new motronic ignition system, so I think you would need to bring that over with the wiring harness & ecu. I have to ask, though, why bother with a swap when you could just get a 91 318is? Once you turned it into a track car I think the weight savings would be negligible, and you get 4 wheel discs with the IS, plus a better starting point with the suspension.
