Well,
Spent the last the few days putting the final fit on the turbo system. I got the entire system built including the hotside, and the coldside. It still needs a bunch of detail work, (finish welding, grinding, and smoothing)
As I said i would, I bought Chinese waste gates. They cost 70.00 ea. When they got here, I took them apart because I heard that they typically were full of excess debris from the machining process, with jaggedy pieces of metal just begging to snag the diaphragm.
I'm here to tell you......they were right.
Every hole that was drilled and tapped had burrs, the hole that was cut for the valve had significant flash that needed to be ground away. Now that that is done,...I left them "gutted" so I could weld w/o worrying about melting the diaphragm. I also heard that the springs were inaccurate,...and I had to check the actual rated pressure to be sure it was accurate. ( especially since I have two of them) I haven't done that yet, but this car is far from running, I'll cross that bridge when I get to it.
The rear waste gate placement pretty well means that the A/C system will definitely either have to be relocated, or eliminated. I planned on relocating the A/C lines before I even bought the turbo,..so it's just one more bump I gotta deal with.
I decided to re route the coldside under the intake,..as there was no room for the front waste gate in my original plan. By clocking the turbo in this orientation, I gives me room for the waste gate, but will most assuredly force me to cut a hole in the hood, and there may be valve cover interference issues. But again, I'm building the valve cover, so I'll try to take that into consideration when that day comes. Clearly, I got two more holes to close up during the engine bay smoothing stage.
I wanted to get this part behind me so I could start on the engine bay I got one more 3" hole to cut for the piping that comes out of the inter cooler going to the throttlebody, and my hole cutting days are done.
