Minimal progress this past week....working on a kitchen project....because "happy wife, happy life" 
Finished oil drain plate and ran oil supply line.

Still working on kitchen project but managed to make a turbo support brace that will bolt to a bell housing bolt. Started carb mounting using a Mikuni carb boot (bolt pattern worked with no mods) so the carb will be rubber mounted to help absorb vibration and possible fueling problems from it...modified boot for vent etc....

Cool stuff going on in here.
What's your source for turbo manifold pipe (and is it truly "pipe")?
They were cast stainless, I got them because of the smaller radius they were available in (space is at a premium!).......I got them from Summit
"Ultimate Headers Tight Radius Elbows" ultimate headers.com
In reply to TurboFource :
Sweet, thanks. That might help me out.
Love the thread.
Another USAF vet here, nothing as exciting as SR-71 welding, but I turned a few wrenches. You ever get the itch to tell a story or two from your time in, then we've got a thread for that.
A. Thank you for your service, you are appreciated
B. Truly amazing fabricating work. I'm excited to see the final product
C. I have a new favorite word thanks to this build: "Fabricobble". I have every intention to use that in the future.
-Bead on tube to engage groove in carb boot
-Wood lathe "machining"
-Carb mounted
There is something very satisfying about that little Mikuni sitting on the front of that compressor housing.
It's one of the original Stromberg CD-175s .... supposed to flow enough air for 250hp draw through...
Now I can take the turbo system apart to paint/detail!
Nice work.
On a draw through, be sure that your turbo seals are fuel compatible.
(apologies if that's covered earlier in the thread, I have not yet read through from the start)
Great build thread, love the updates while keeping the original character.
The question of lag came up previously. I don't recall my '81 draw through carbed turbo 2.3 Mustang being unresponsive, not fast with only 137hp (if I remember correctly) but not unresponsive. . .
One of the advantages of a draw through system is that when you close the throttle the compressor is now spinning in a vacuum....it doesn't slow down and possibly speeds up (there is no air to compress).....so when you get it spooled up it stays that way between gear shifts. Other benefits to this ancient technology is a simple fuel system without the need for high pressure or boost regulation. An intercooler will not work but water/methanol injection can easily take it's place. Another advantage is people will not think it can be fast....(look to air cooled vw guys if you want to see fast draw through systems...).
I finally found an old compressor map for my T3 and I think it will be fine....time will tell!
A couple pages ago you said you wondered if anyone was reading along. Yes. Yes we are.
Turbo system mock up basically complete and taken back apart and head back on the bench to set valve clearances (didn't expect the turbo system upgrade detour to take 2 months....) think I am going to throw a rebuild kit in the turbo while I am at it....
I will be adding water/methanol injection to TCST...has anyone used AFM's Mr. Freeze? Any comments?
I like the simplicity....or should I go with Snow? I will be injecting pre-turbo .... (the original build from 1975 sprayed right at the compressor wheel....and there are no signs of damage....)
