So I am about to begin to slowly gather things for my girls y7 auto to manual y8 trans swap I am planning this summer. After reading through numerous threads on here and doing quite a bit of research. I feel confident enough to do this swap, but now I read that I will need a the manual intake manifold also. Why can I not use my regualr auto manifold. Thanks for any help. Also I know I will have to swap my ecu but will I have to change the harness over to the manual one also for the ecu to plug up?
