What’s everyone’s personal preference for wastegates (Internal wastegate vs external wastegate) and why?
Please no bashing each other, I’m interested in everyone’s opinion on wastegates here.
I personally lean towards external wastegates 90% of the time as they flow great, almost all use vband connections (gaskets/hardware pre turbo is always a failure point) and can be recirculated if noise is an issue.
That said internal wastegates also have their place, keeping things simple/cost effective when compared to external wastegate options.

Super throwback video of my KA24e-T with a Tial external wastegate having some fun in AZ.
