First off, I've been searching about this swap for a while now. I know it's easier to do the swap on 01 and earlier 2gs. I pretty much read all the threads on this swap but no real info for 2003 GS. But I have the car and engine already. This is my plan, please chime in and Lmk of I'm going in the right direction. Thanks! Going to use the stock GS harness and ECU with the AEM Ems v2 for 02-05 gs300. Already have a W58 trans, but not sure if that's what I'm going to use just yet.
