Got started on the wiring. Although it dosen't look like much, it's mostly there. Just needs soldered and pigtails added and such.
Turbo showed up friday.
And here's what I've been working on for the past few days...
As of tonight I need to mill the flanges flat on the manifolds and T4 flange, then i can weld the V bands in place (nothing would line up once there milled). Then I need to grind all the welds of my crossover.
Please don't poke fun at the welds, they'll hold but they look like total ***. I can't get a nice looking weld migging stainless for ****. I didn't think it would be harder than mild steel but I was in for a surprise lol.
If anyone has any experience migging 304SS let me know any tips? I'm using .030 308 wire and 75/25 argon/co2...

I'm not picking here, I am just curious, but is it ok for the header tubes to be different lengths from cylinder to cylinder? I mean is it different or alright since it is going to be turbo anyway. I ask because I always thought each header tube was supposed to be the same length. It looks great and you are making awesome progress, I was just curious.

On N/A cars you want equal length. It has to do with the pulse tuning/scavenge affect... creating less pressure behind the pulse to help evacuate the cylinders (if I remember correctly). With a turbo, the back pressure is so high there isnt really any scanvenge affect going on.

As I have found out lol... It almost seems like the lowest wire speed I can get a steady weld without the weld wanting to suck back towards the tip is to fast of a wire speed. But turn the wire speed down and it wont weld at all (the weld wants to suck away from the metal and back towards the tip. Oh well, there penetrating good, just look like poo. That's what grinders are for

It's pretty time intensive. I'm using a grinding stone to get the weld down nearly flush with the tubing on each side of the weld. You have to be really steady with your hands and only grind the weld itself with the stone, DO NOT just run the grinder back and forth across the weld hitting the tubing to. It will grind the tubing a lot more than the weld and just make it thin and more prone to cracking. I'm already using thin steel to save weight so I have to be extra careful with that. Once the weld it pretty flush to the tubing I have a.... well I don't know what you'd call it... a sanding flap wheel? lol You can get them by the grindstones at lowes. I'm not sure the grit I'm using. I'll get pics and info when I'm out there today and post them up tonight.
Once I'm done with all that I'm hitting it with the DA. 180 grit I think.

Got pretty much all the hot parts up to the firewall mostly done. I'll be finishing it all up on the engine outside of the car. (Such as the wastegate plumbing and lining up the crossover v bands exactly, etc.)
Plenty of plug clearance
Downpipe
The past few pictures were over the last couple days. Tonight me and my buddy pulled the engine.
The $28 kart I made.
Also serves as a creeper lol
Lubing up the swivvel on the chain haha.
Rest of the pics from pulling the engine.

Hey man I'm also 19 and I'm doing a turbo build on my 94 z here soon and was just wondering what all that exhaust tubing cost you if you don't mind mr asking?
Very nice build though and nice fab work on that throttle body bro.. How long did that take you to fab up??

******* badass project and work dude, especially for such a young age, I can't do that and I'm 23.
I can't figure out where you lifted the car from, let me know.
Thanks.
In for the rest of it.
