Haha true, not trying to cheap out but also not trying to break the bank and trying to save money when I can. Mainly I just want to have fun and build my own kit.His stated goal is to not pay for an “overpriced’ turbo kit - so budget seems to be king here above all else

Update:
I wanted to give an update to this thread. A-lot of people doubted this but I still have full intentions on doing this build. I got an old Flux welder free from a buddy of mine and spent the last two weeks learning how to weld. Been welding together different scrap metals and exhausts I got for free for practice. Its going really good and I feel confident enough to start building the top mount turbo manifold. I ordered the flanges pipes etc and plan on starting it in the next week or so once all the parts have arrived. Might upload a few pictures of welds if people are interested.
I bought these flanges to mount up to the engine. The holes are roughly 40mm or 1.5 inches. I bought a bunch of 304 stainless steel 10 gauge pipes with a 1.5 inch diameter with all different types of bends etc.. I bought enough pipes to mess up once or twice just in case. I'm still debating if I want to go dual 38mm wastegates or a single 44 mm wastegate. Was wondering if anyone had an opinion on it so far.
Update for the turbo Im working on finding a good condition used turbo. Im probably gonna end up going with a pulsar 6466 .96 ar . I might go with a ebay GT3582 turbo not sure yet.

Whats a "flux welder"? Do you mean a stick welder? TIG or MIG?Update:

Flux welding is a special kind of MIG welding where the gas isn’t needed. The wire is filled with flux, so when you weld the flux combusts into the gas. Only con is flux welding is a little messy and has a lot of splatter. Other than that it’s just as strong as mig welding if not stronger.

Ok cool I've not had exposer to it before only stick, mig and tig. I went looking for info and this video seems good esp from 4:55 with regards to machine electrical inputs and outputs V spatter.

I’ve spent hours watching tutorials and videos like that for advice. I ended up buying some new wire the wire I have has been sitting for years and is some random Chinese garbage. New wire + anti spatter spray and a wire brush wheel should make some pretty good welds!

A major issue you will have with this welding type is distortion. It's an issue with TIG as well but TIG due to the shielding gas that helps with heat control is the best at controlling it. The distortion means that at mock up stage where everything fits on a tack welded together piece by the time you get it all welded together it's quite significantly misaligned so you have chassis clearance issues etc. Professionals at exhaust construction usually weld as they go and also know how to compensate for the distortion. Something to watch out for.

Update: disconnected and removed everything from the hot side of the car
Taking measurements and starting to weld the turbo manifold. Trying to figure out what all the lines I disconnected are for.
Other than this my turbo doesn’t use coolant so I’m capping of the coolant lines. Not sure if I should reroute the back coolant line or cap it off need to do more research. Will post more updates throughout the week.

it’s hard to get consistent penetration because it’s so messy. Flux is better used on thick material rather than exhaust piping. And needless to say, it looks terrible no matter how good you are at welding. Gas conversion are normally cheap. It’s the bottle that’s the expensive part. But I would highly recommend doing it, for every reason possible.
