hi im fitting a cosworth engine to my mk2 escort and needed i little help


i dont know much about it but i was thinking about fitting a external wastegate and dv

is it possible to run both.

do you get a better sound from an external wastegate to the internal one?

are they hard to fit?

and most of all how do i pick the right one and how to fit it?


going to be running garrett t3 with greys with 3bar map
