Is a 40mm WG Enough for a 60-1?
I am piecing my turbo upgrade and I was wondering if an open vented HKS 40mm wastegate will provide enough vent for a 60-1 with a P trim .81 tang turbine on a stock 13BT ser4.

Yeah that's big enough. I ran a 38mm on my old set up and it was just fine. I had a .84 a/r.
