After a long hiatus, it's time to start putting together and welding the custom TT, though I have one question
I'll be using Garrett G25-550 turbos, what would be the appropriate sized wastegates for those turbos? Most likely daily driving around 8 psi, max would be 12ish before the built block is put in
Currently have Tial 38mm for the kit but I'm thinking I might need 44mm
