64 Chevelle, 5.3, TC78, E85 Not too exciting. That's why I am going turbo. I've had the car running NA for a little over a year with the best quarter mile time of 13.2 @ 106.
Let me start by saying this is my first turbo car, and i have never welded before, so please feel free to critique and advise. Now for some details...
2001 5.3
HP EFI
Turbonectics TC78 .96
Truck manifold V-banded down and forward
2.25" mild steel hot side
3" down pipe
50 mm BO
45ish mm WG
80# Seimens
255lph pump x 2
E85
Th400
A2A intercooler to follow
I started fabricating this morning. So far the manifolds are clearing everything with the V bands tacked on.

I'm gonna borrow my neighbors tig so hopefully I pick it up fairly quick. And the turbo selection was a combination of a few things, Huron speed, budget, physical size, and my power goal should be close to maxing it out with good spool time.

Worked a little bit more on it until I ran out of wire in my welder, and I'm almost out of gas. I've got about half of it finish welded. Next is the down pipe.
Only parts I still need to order are my wastegate, oil feed and return stuff, aluminum tubing and couplers for the cold side, and maybe a few odds and ends.

Your setup is almost identical to mine. Differences being mine is a 5.7 (but will be getting an L33 soon) with a log manifold on the passenger side due to clearance, 2.5 stainless hot side, T-56 and mine is in a G body. I'd like to see how yours works out!

Yes it will. My first turbo anything. I am hoping to be surprised.
I got lucky with both manifolds fitting the way I wanted, down and forward. I would have done stainless too, but it would have bumped my budget up a little too much.

Most of the fab is done. Knocked out the down pipe tonight, 3" with no muffler. We will see if its too loud. Eventually it will have a muffler with a cutout and exit point down and towards the rear behind the rear tire. Still need a waste gate to finish. I am debating on the Denmah special, Ebay EMUSA or paying the money for an expensive one. It's not my DD so Ebay may win this one. Enough talk, here are a few photos.
Old nasty exhaust I still need to remove.
Pretty simple, but leaves me at a place where I can continue towards the rear when I am ready.

So I've got it fully welded other than the waste gate to the down pipe. For the waste gate I went with the 46mm Precision. Sorry no pictures yet because the memory card for my camera died. I made and installed my oil feed and return lines, tapped the timing cover for the return and fired it up yesterday. I will have pictures and a video hopefully tonight or tomorrow.
I still need to do my cold side and I have a question, Should I run 3" or 2.5"? The outlet on the turbo is 2.5". I am running non intercooled right now so it will only be about 18" long. Or will it not really matter?
