hot side piping diameter?
Hey guys I'm in the planning stage of building a 351w turbo kit. It will be a stock bottom end, 200 cc heads, super vic efi intake, with a S475 turbo with 1.10 A/R housing. Have the motor already, and parts are ordered.
A friend of mine will be fabricating the hot side out of mild steel. What diameter piping should we use? 2 1/2 inch? I read somewhere that the diameter can affect how quick it spools..
