M20 Turbo => M50 turbo fun.

Yes definitely an odd size. BMW just has to throw some curve balls in there. The strangest thread pitch combo I have seen is on my Land Cruiser the seat belt bolts are a 7/16-20. The reason I found for that is so that they do not get mixed up at the factory and use the wrong bolts because every other piece of hardware on the truck is metric.

Yea I just wanted something so I could mount up my turbo and finish the fucker. I can really only work outside on the car on the weekends. By the time I heat up the garage enough to do anything on the week nights, it's bed time(8pm- get done with work at 5.) so I just wanted to find something local so I can get some stuff done. But anyways, I ordered from the carr

I'm stupid and should have bought a different manifold but it will do for now. My turbo is t3 exhaust housing split, but the manifold is t4 open(future turbo). So I built an adapter quick at work. 1/2" thick mild steel. Cold rolled. I still have to ball end it but I had to eat dinner and I'm impatient(I'll probably do it tomorrow).
More Pics!

So my turbo didn't really fit with that manifold... So I cut some of it off.
Fuck you and your 5 bolt flange.
Sorry.
Anyways, I'm welding a v band flange into it. Not sure if 4" or 3.5". I want the smallest one but the smallest I think I could fit would be 3.3" anyways I'll have to look into how they measure v bands.
Got the turbo mounted, but my brother is in the garage and it's a little bit too cold out to work on it. So.. This weekend!

So I acquired a piece of 6061 .500 thick 6" diameter aluminum to use as a surge tank. How much volume do I need?
I am thinking of mounting the dual 044's inside the tank. I think it would be much cleaner and I've seen it done. FUEL RAIL IS STILL NOT HERE DAMNIT.
These bad boys are big.

Awesome! Wish I worked in a machine shop, so many toys
I've been working there for six months now(today-woohoo I get a raise) and it's honestly amazing. I love doing what I do. It's never the same, and I'm not just doing one job.
Oh, and having the keys to the place is just a bonus haha. And it's always 72 degrees in there so I have never broken a sweat.

So Mitch dropped his MS3x off at my place for testing and whatnot, and he had purchased it from someone who built it. Needless to say what I saw was a bit scary, and it doesn't work.... I will let the pictures do the talking.
Parts not sitting on the board, touching other things
Melted pots (grey block)
More parts off of the board
Long wires that should be trimmed, melted PCB, some wires were touching the case
Total mess
Very melted, some pads pulled through, solder pooled together

I should upload pics of mine for comparison now lol.
I didn't get around too it last night, but I will see what functions tonight and go from there. I see 3 issues already

also, I just about finished the design of the surge tank, just not sure how many litres I need. The two pumps will be partially submerged, such as this
also, My brother is back, and the m20 is getting worked on!
