What car? It probably depends on what you want the end result to be. You won't be able to DIY a Porsche Taycan, but basically if you can do an engine swap on an ICE car, you should be able to do a semi-ghetto EV conversion (i.e no fast charging or advanced thermal management, but safe and robust enough to run daily for years). Tons of people are doing it on YouTube.
