Awesome input buddy! Even though I'm not doing the welding, I still really like to know all this and I appreciate you sharing. I'll talk to him about all those points.

There will be three vbands on each side. It will be a massive pain in the A$$ if I don't have three. Also, that should allow a bit of play for angles. First vband will be on the exhaust manifold, second will be near the frame and last one will be at the turbo.

I'm shocked at my progress on my own car! Weird to say... but I only imagined doing stuff like this.... Albeiet I'm not the best at it... but hey, that doesn't matter (if it ends up working. lol).

Finished snake-zilla on the passenger side tonight, it eats pies.

---------------------------

I wrestled around with the last leg of the connection for about 3.5 hours. End result, worth it. During the process... many swear words and quotes like "F@ck the, G0D d@Mn turbo SyStEm..." and a lot of other variations of that.

I used 3x the amount of pies I thought it would take for the whole thing just on the passenger side.

Is that stainless tubing? If it is. You have to purge the inside of tubing with an inert gas, like argon to get rid of any O2. Otherwise the backsides of the welds will sugar and not be strong.

You're going to have fun tacking all those joints together. Which is what I would do before turning over to the guy welding it. This way you know it fits.

Ok, so before I saw your post Rusty I dropped off the tubing to a welding shop because my buddy's shop was extremely busy. I asked them to tig w/ back purge ( which didn't throw them). I then told my buddy later in the day and they were just shaking their heads. That's because the thermal contracting can change everything up to a half inch..

Long story short... I called the welding shop and asked them to tack it only. I felt bad.

When you got that many welds in a short section. You start at "A" and "B" and work towards the middle. But leave the middle alone. Weld everything up but the middle. That's where you put the final piece in and the final weld.

Pie cuts look neat. But that's where you will have most of your problems. Pipefitters try to avoid them as much as possible.

You and what my buddy are saying is about the exact same thing. Very cool to hear the same stuff from two people!

IG@gbrettin
Driver's side hotside complete. Pictures don't tell the tale of how many times the pipes were attached/detached. ���� ... Next up... Downpipes.

------------------------------------

The pies are REALLY nice on the driver's side. Not saying the passenger side is bad at all, but the driver's side has no gaps at all which will make welding life easier... My buddy Dave was excited about that. I will need to buy him a steak dinner and pay him some cash when all the welds are done. I yell across the shop saying "SORRY DAVE" for every pie I add.

I want to give some context to the fourth picture in. I got pissed off and ripped the pies apart. The charge tube didnt clear the frame area properly. After that was resolved, I started on the bend down and out from the turbo. First attempted had the tube hitting the tire. THAT TIME I murdered the pies apart...Which might have been when I actually took the picture. Even though the thought of adjustments will need to be made, it starts getting under the skin around 8-9hours in.

Another buddy, Chris (owner of the twin turbo G8), snuck the pictures of me giving murder thoughts to the hot side.

First picture in the lineup... My Juke inbetween two trucks the shop owners built (custom). The Dodge was just completeted. The owner is a female (holster the pecker jokes. lol)

You need a bender. One that bend tubes, not a weekend bender. But maybe that would help.

Please ask if you have any questions. I figure this can be a good learning thread for what you might want to do AND for stuff not to do. I had only fundamentals before I started my swap and jumped into the deep end because I wanted to get my hands dirty with everything.

Also, thanks for following the thread. I'm going to be completely honest, it's a real pain in the d1ck to get photos while working on something. Your comment validates why all these pictures are useful. Also... I think it's good to remember the burden of the processes.

Bottom line... I'm glad people enjoy it and take the time to look.

I absolutely hate stopping to take photos during a project. I try to make myself do it and then take terrible photos at poor junction points in the project

The documentation in this thread is unbelievable. You have gone way above and beyond sharing your unique project with us. Thank you and kudos

Need? Nah. The shop has done this a bunch of times. It's a slow process for me due to experience. The shop may pick one up in the future. but.... I think the one they want is like 30k-50k? That's out of my ball park anyway.

well, looks like the whole thing got tacked at the welding shop. Looks like they used baby tacks and nailed down the flat spots. Hopefully this works out awesome! And if not... I'm not afraid to cut it up (don't be surprised if you see new pictures of me doing that... lol)
