Internal wastegate block off on stock turbo option?
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!

Been on Killer B EWG headers for 30k using their block off that come with the kit with zero issues... no need to weld.

Nice! I was lucky enough to be able to snag a new header before they “discontinued” or pulled them off sites for sale. Pumped to get them swapped here in the coming weeks . Appreciate the reply

Yeah. They still have and sell the non external header. From what I get out of it, anything that is emission related is a no go. So catless j-pipes are gone as well (sold as new anyways). I did some searches last night and seeing these parts disappear from sites. Kind of sucks for the future that these options will be no more.

I made a pattern and had it cast to create a nice smooth housing and then had it brazed into location, then made a plug to seal the flapper assembly. |
