Did this this morning.... Made the uppipe.
Parts......
Used an existing manifold flange and pipe, welding it to the extra intercooler pipe I had
The turbo flange is 2.75 opening and I had to get there from a 2" pipe, so I bought two reducers and welding them in and up!
And the finished product.
Cost me $10 for the two reducers and the flange.
Next is the downpipe and 3" exhaust. I am probably going external wastegate, if the Audi 5000 wastegate I got an EBAY is any good.

great work man! +1,000 for inexpensive parts!
You need to stop by our shop sometime!

You water test those welds?

couple things about the welds-
turn up the heat for the inside 90's on the flanges, down a little for the butt welds. the heat for the weld connecting the two reducer pieces looks about perfect. some of the others I gaurantee you will crack, probably pretty quickly.
let a puddle form before you start moving
what wire setup are you using? some welds look like the wire is sticking a little bit or something.
if its flux core you ought to take some time to really learn how to use the stuff, its much harder than solid wire and gas.
you going turbo now?

Finished the downpipe..... Its just 2.5" for now, didnt have any 3"

If I could weld aluminium, and had the oil line, the damn thing would have started tonight!
>:D
Notice how the turbo out goes so nicely into the supercharger!
Also notice how restricted my inlet to the turbo is
I plan on making a weird box thing with flat filter for the air box.....

I am using .030 wire, CO2....
I am getting better.
on the inside of the turbo flange, I also welded the inside and ground it down, that should help alot....

Not that I'm ragging on you, but do a lot more test welding on scrap before welding a finished product that you're going to put into use - otherwise it's not going to last long.
Using pure CO2 gas, while that works, is encouraging oxide formation and will eventually trash the welds - sooner rather than later; get CO2 and Argon mix, like 80% Argon and 20% CO2
a little more expensive, but you won't get near as much splatter, the arc will be easier to control
I've also heard that a mix of 70% Argon, 28% CO2 and 2% O2 is starting to become more popular for welding steel, but I haven't used this combination myself.
Anyway, it looks like the pure CO2 is making your arc hard to control, dump it in favor of a mix and you'll have an easier time getting better

A lot of that is not accurate...
Running pure CO2 is not really a problem, apart from it just makes it more difficult to weld...as the bead is more likely to be contaminated... Your welds don't look too bad for a beginner, or for doing it on round stuff (total PITA!)
On your next bottle fill, I would suggest running 75/25 (75% argon and 25% C02)...That is what I use and the welds turn out really nice. (plus I have been welding for a few years lol)
Scuzzy, the gas you were alluding to is AB trimix...but it is a mix of Argon, Co2, and Nitrogen...and is used for welding stainless, which requires a hotter arc...so I wouldn't recommend its use on mild steel
Keep on truckin' Doug!!

All of the pipe has been stainless.

Just speaking what I know and have been taught, 555; and I thought he was using stainless, hence an argon mix would make it easier to weld.

Stainless is always tuff to weld hot enough, why I usually use mild for pipe sets. Dougs welder actually works pretty damn well. I used it to peice together some stainless last week, and ya, the CO2 is going away as soon as the bottle is empty. Its just kind of hard to waste what you already got especially when on a budget.
I've never had good luck with the trimix either. Sure its hot, but it really sucks just blowin through everything you touch with it.
Id just water test it, and if it cracks, fuggit. Just reach back up there and fix it when it does.
Doug, I love ya man. You are an excellent friend and an inspiration to me. Cant wait to see that thing beat modded STI's.

Ive heard(and there is a lot of hearsay when it comes to welding technique and specs) that pure argon is the way to go for SS.

I found an AWESOME FREE stainless bar for building brackets....
They are called knives!
Just get some stainless knives for free from the kitchen and weld them up!
Or go to Goodwill and get some for $0.25 each.....
I welded up a stainless butter knive to a stainless tube. Damn strong weld...

Butter knife brackets are an awesome innovation.
