Slant 6 Turbo... Tight quarters. I could use some pointers

Maybe place the turbo up high and modify your engine box to allow it. I debated putting mine up high enough at one point that I could drain it into the valve cover. You could also find a way to put it on the other side and drain into the fuel pump block -off if you're going for an electric fuel pump (which you should be).

Your goals for turbo are a lot like mine - you just want to do it, not really for the maximum power, but just to have it. I get it. You'll get there.
