My single turbo Wayfarer Ute build

Haha Yeh it'll make alot more sense once your actually looking at it. I was confused when I first started too..

Just leave the top fitting open if you don't plan to use it.. Did you get any lighter springs with the wastegate? I always like to start low (in boost and timing) and slowly creep up to avoid engine damage on a new combo

I also always get my signal from the intake manifold for the wastegate, as you will get a pressure drop between the compressor housing and the intake, you won't be getting the desired boost pressure into the engine. Eg. When comnnected to the turbo compressor, it might be pushing 15psi when the wastegate is open, but the intake is only seeing 12psi. If you get the signal from the intake manifold the gate won't open till the manifold sees 15psi.
