70 dart swinger slant turbo build and mild restoration
So what mm Wastegate should I use and does any old bov work?
Both the blow-off valve and the wastegate need to be correctly-sized for the application. If the blow-off valve is too small, it won't allow enough of the pressurized air to "escape" the system and damage to the impeller could ensue.
I am the wrong guy to ask about this stuff, because I am not well-versed in the vagaries of slant six turbo specs, and have, basically, "lucked out" with regard to my own stuff. I am not sure that having a waste gate that is "too large" could actually hurt anything; it just wouldn't have to open as wide to get rid of the excess exhaust. But, I am sure that there is someone on this FABO discussion board who would know the answer to these two very good questions.
One such guy's name is "PRINE," and he seems to have comprehensive knowledge of these systems and their spec-requirements. Maybe he'll see this question, and answer it. It's over my head (obviously!) Sorry... :banghead:
