I flipped the vacuum pump bracket 180 degrees. Turned out pretty well. In hindsight, a vacuum reservoir would have been nice addition. If you're utilizing vacuum hubs frequently. Sometimes my blend door actuators would take a few seconds to extend/retract after the hubs locked.
The oil drain is really, really important. I ended up trying three different pan options. I pulled my engine 3 times until I got it right. The best option is to drill a 1/2" hole through the upper pan, behind the gasket path and weld an aluminum -12AN fitting at a small angle to the pan.
An improper drain will either have one of two consequences:
1) Leaking from the pan gasket
2) Pushing oil past the compressor/turbine seal
Hard to tell from this photo, but be sure to have a smooth downward slope from the charger drain to pan. Different engine, but same concept.
Here's what another member has done as well, but as you can see, has a small leak.
