My friend is doing a turbo swap on his 2013 wrx. Shooting for 375hp tuned in Ohio at Pure Tuning. He offered to give me his stock turbo and anything we pull off his car to do the swap. With my car hitting 110k just yesterday I would love to get a free turbo from him with only 20k. Does anyone know what would be required to retro fit it? The only problem I am aware of concerns the up-pipe flange. Being different from 07' and 13'. Assuming the up-pipe and downpipe from his turbo could be used (maybe a custom up-pipe with the correct flange)... would you think I would need to get a custom tune? I'm not really sure if there's a significant difference in the two turbos
