I'm making progress on the wastegate return pipe. I determined I do not like the angle of entry into the exhaust, so I'm going to cut off that angled part and make it more of a 45 degree entry instead of 90.
Overall I'm pleased with the progress, considering how little time I'm able to put into it.
I ended up making a 38mm flat flange because I was short one. The moral of that story is: keep everything. :) The piece of metal was from my buddy's F150 diesel that we replaced the water pump in 5 years ago. It was part of the A/C bracket.
Tomorrow I'll finish the wastegate return, modify the hot side intercooler piping, modify the ambient pipe, and if I have time hook up the water and oil lines to the turbo.
Sorry for the cell phone pics tonight.
The A/C bracket, I mean flange:
This is the angle I'm going to tweak to more of a 45:
