Default S400 T6 LQ9 Mustang Turbo Build (5.85 @ 118mph)

Just getting started on my build. This is my first turbo kit and pretty much my first time to TIG weld. I have a buddy on another forum who has given me tips online, but other then that this is a learn as I go deal (so go easy on me). Went with a B/W S475 T6, passenger truck mani on driver side, c6 passenger mani on passenger side (to clear a/c compressor). 2.5" mild steel crossover, custom merge, 2 38mm wastegates, etc.

Here are the pictures so far, I will update as I go.

Started with the merge and the drivers pipe:


Then I made the down pipe (will be exiting out the side of the front fascia in front of drivers front tire):


Next I started on the passenger pipe and wastegates:


here is how I have the passenger side tube coming forward (notice the wastegate off into the wheel well)


Here is a better picture of the passenger wastegate (and I am going to make support braces for the wastegates since they hang so far off the pipe):


Waiting for my V-band assembly to get here to finallize the passenger crossover:


Clearance with this giant turbo/down pipe is TIGHT:


View from up top:


Cut out the fender well for the air filter:


Also machined some solid motor mounts for my aje swap k-member since they don't sell any and with the frame mounted turbo I need them:
Stock poly mounts:

My custom solid mounts:

Here they are installed:


I ran out of Argon so hopefully my progress got halted, but hopefully I can finish up the hot side on my free time this week and get started on the cold side.

I'll keep updating this thread as I go.

pretty much, ls6 intake, 230/230 turbo cam, .660 springs, 96lb injectors (and a big return fuel system), 3 bar os.

going to run meth/water injection to hopefully keep it alive.

Appreciate it. I wish I could spend longer with it each time, but I work mon-fri 8-5 and the car is at my FIL's shop that is about 45 to an hour away so I can only get out there to work on the weekends (and even that can be tough since I have obligations at the house like mowing, pool, etc.). I wish I hadn't have run out of argon on Saturday night since Sunday was pretty much useless with no ability to weld. on that note it would have been pretty useless anyway since I didn't have the v-band I need to complete the passenger side pipe.

Looks good.

What is wrong with that T6 flange in the first pic? It looks all sorts of machined wrong or something.

no, it's just like that around the borded because of the way the pipes came in and i welded around the inside seam, didn't come out perfectly square.

Finished up the cold side today (still waiting on my 4" to 3" silicone transition for the throttle body and my 3.5" to 3" silicone 90* elbow for the turbo outlet, and I need to order bungs for my IAT and meth nozzle).

Here are some more pictures, I welded everywhere I could on the cold side pipes, there will only be couplers at the intercooler, 1 in each fender, and at the throttle body and the turbo outlet. This was the minimum I could do since the parts have to be able to fit into the fenders.





Still need to cut the fascia cover for the downpipe to come through but want to make sure I like it before I cut that part up.
