Would this cause any lag?
Also whats the dimension on the tophat, 63mm?
dimension of turbo underside bit 51mm?
Is running 3"/76mm Intercooler piping a good idea, or recommended to go for 2.75"/70mm or even lower down to 2.5"/64mm?
Or am i guessing bigger is better...
My intercooler outs are 63mm, Obviously id need to use a enlarger/reducer to go 76mm-64mm
