The qrj comes in a 38mm flange.was trying to find a direct fit without having to rework the pipe with a 50mm. I did see the vids of the tial 50mm swap and it sounded great that's why I was asking about the qrj size.....

I did speak with a very reputable guy at Z1 and he said he seen a lot of guys use a 38mm wastegate with a lighter spring cause it had a larger opening than a 38mm bov
