Hi everyone. I'm about to start welding up a DIY turbo manifold for the 2.5L in my Spirit. The idea is to relocate the turbo from behind the engine to over the transmission (nearer to the battery area). There is no need for anything fancy, just a simple "log-style" manifold but with a long pipe and flange for the turbo (GT3076) and an external wastegate. I believe the Bonneville Chrysler Lebaron had a similar set up.

I'm looking for any recommendations as far as the size of the welds els/tees. It looks like I may need a way to increase the pipe diameter once in gets to the turbo flange.

And if any of y'all have any pictures of this kind if set up, I'd super appreciate the visual.
