I have a ford with a 12 valve in it im re working. Swapping the Zf6 for an Nv4500 and wanting to replace the hx35 over s400 for a different setup. I can get a s475 with the 1.32 ar housing for a good price and was wondering what a good top turbo would be to not overlap the primary but not be laggy as well. Im running 5x16 injectors 215 pump with 4k springs 141 delivery valves. Also benefits of running a gated turbo vs an external ED waste gate. or not running a waste gate?
