I am building a carbed turbo setup on a fox body with a 302 based motor and T76 turbo. I'm using 1 5/8 BBK shorties with the flanges hacked off for headers(this is low budget . What size should the crossover pipe from the driver side header to the Y be? Should the placement of the waste-gate be above where both exhaust meet into the Y or does it not matter. Also, can anyone recommend a waste-gate to use? HP levels are expected to be in the 550-600hp range. Any help is appreciated.
