was just wondering if a t3 turbo off of a 280z would be incredibly too small for a 305 or maybe a twin setup with two t3 off of 280z because i can get one for free and probably get another one for cheap not looking for anything insane maybe 300hp from the setup or would i be better off just getting a bigger turbo. thanks in advance
edit: the ar is .43 iirc

too small, sorry. Maybe 2 would be ok for "just" a 305
