Just in the process of going from internal wastegate to external on my T3T4 v6 set up just was wondering what size wastegate everyones using on there setup
on a turbo that size id be looking at a 42mm minimum, maybe even a 50mm.. Buy Tial, HKS or Turbo smart.. not cheap chinese knock off, else your engine insides might come out for a visit via the side of the block..
