Can't seem to find much info anywhere on swapping to an external wastegate setup on a stock turbo for the FA. So here we go! Soon I will be swapping to a killer b header with external gates and I just can't seem to have it in me to weld the internal gate closed. Has anyone used or tried the grimmspeed universal block off or got creative and made their own? Their sites states that it will work with FA's stock turbo but would like to know if anyone has used this as an alternative to welding and have had success with it? Would love to hear what others have done!
