Hey, at least the swirlpot came out great!
When I installed my gas furnace I needed something like that, just a lot bigger. I went to HVAC/mechanical shop that was next to my work and the guys there made it for me in an hour in exchange for a 6-pack of Blue Moon. Just skip the office and go straight to the shop door; those are they guys you want to talk to anyway

Yeah I have an HVAC buddy, I was picking his brain a bit. But I wanted to see if I could make it .
The catch can Is OK but the welds are not great. I think its gonna get painted wrinkle black though.
Sean pointed it out and now I can't unsee it that with the white engine bay, It would look cool if the intake manifold and turbo compressor matched the valve cover.

well shit. I was skeptical of the painted IM but that looks freaking fantastic!
Pops did good work on the stove adapter too

I hear a speed sensor works fantastic! Maybe a vendor... like Mike Hood @ Ringer Racing could give you the dimensions and thread pitch if necessary.
Seriously though, great work moving forward. Fabrication can be an exercise in equal parts cursing and patience divided by eureka moments.
And LOL at freezing while working in +2C weather.

Yeah my weather is is not as bad as yours, I shoudn't complain... But the heater will most likely get the shop up to 45-50 F if I get it burning good for a while so I can handle that. I just hate not being able to feel my hands.
I guess I could go one of two ways, wither make a small taper on the lathe and put in a small recess for an O-ring , or just just get the sensor and pop it in there. I just wouldn't know what to do with the sensor output, but maybe it could come in handy some time down the road. It's about $150 which isn't too bad. But if I add up all the "it's just $150" in this car it's going to be astronomical.

I was mostly joshing you about the weather... it's all relative, and you have to contend with (up to) 100% humidity which is basically unheard of around here. Still, gloves can be... handy. I'm a big fan of HyFlex gloves made by Ansell -- mostly because they're fr... donated by my workplace -- or some simple woven cotton liners with latex gloves over top. You'd be surprised how much heat you can retain with either option, while maintaining dexterity. As always, the key to keeping cozy in the cold is warm feet and hands.
As for your trans fluid options, seems like lately the tide has shifted from Motylgear 75w90 toward Fuchs Titan Race SYNCHRO 75w-90. I'd wager either is a fine option especially as you're not encountering sustained bouts of -40 in your area.
Have you considered going with the higher zinc content PSF found in Redline vs. OEM?

So the PS pump bracket works nice. Now to deal with the lines. I could do full custom from rack to pump but I think it might be better to use a barbed fitting on the low pressure bigger line and a new line for the high pressure side if I can find out what these fittings are . So sort of metric bubble or something ?

Line is about 12” short
Good clearance for the rad
I guess before I get too far ahead of myself I have to plan out where the power steering reservoir is actually going to go .
I can locate it by the coolant reservoir , or put it where the catch can is/was on the firewall.
If I go at the firewall one of the stock PS lines will Work and only the high pressure requires re-work. But I have to redo all the AN -12 breather lines .
Will look at it next few days .
The other thing I need to start looking at is where I can fit the oil cooler . So I’ll put in the alternator and see , I was thinking that the stock URQ intercooler location would be best as far as short runs of lines.
Both fittings are -8 and can either be on top or on bottom.

My plan here, starting with the power steering.
I'd like to figure out what the fittings for this high pressure hose are, so that I can leave the metal line at the rack and just make a new line. Does anyone know what type of fittings these are?
See pic below, I need to remake hose No. "31" at a custom length.
I know the banjo is an 16MM just need to check thread pitch and see if it has any sort of a check valve in it or if it is just a banjo.

Hints welcome other wise I will have it remade one way or another next week.

Couple things done today but not much .
After multiple trips.... Will verify , test fit tomorrow... I May have found the fitting that will allow me to put a custom line in for power steering . This fitting *should* screw on to the metal line with a male flare coming out of the rack , and adapt to JIC (AN) . At that point any hose store can make me a custom hose length .
We’ll see tomorrow.
The store has a couple stages of hoses they can use . One is good to around 1000 PSI the other is 3,000. Pump says 75 Bar on it which is close to 1100 psi - I’m surprised it’s that high .
Catch can installed .
Oil
Cooler fittings. M18x1.5 to AN -8
Potential oil cooler location ? It’s either here or in front of the rad, bottom side . But I was hoping to have shorter lines that that. With a simple heat shield from the header this spot may work .
Speed sensor plug, and a little machined sumbitch to hold it down
This is the only
Power steering reservoir I could find so I cleaned and flushed it and found a spot for it . We’ll see if it works well here as other things get added to the bay

Is the reservoir going to be higher than the ps pump? i think it needs to be for purposes of air trapping?

It is yeah, I have the pump down pretty low at this point . I’m pretty much set on pump location but the reservoir could move too.
Had to rework the bracket again because the belt line was off a tad and the belt was so close to the bracket .
Welded on a boss for my tensioner to bolt to.

Finally ready to throw a belt on the PS pump and Alternator . Linkages done .
Custom power steering line is finished .

Just need to finish one small adapter that I think will have to be made in the lathe . Need to make a conversion from this (unknown?) fitting at the rack to JIC

You should be able to use a metric male concave seat (inverted flare) adapter. Not sure of the size of that one, but here's an example of M14x1.5 to -8AN:

Yeah that’s the last piece I need to figure out alex . Obviously no one at any local stores knows what that fitting is. I was looking at trying to match the angle and make a custom one on the lathe... but I’ll try this first .
I have the pump end sorted now .

So hopefully the concave piece will Work for the rack connection. The proper size for this application is M16x1.5.
This is a metric adapter M16x1.5 threads fitted in but without a seat in it .

Got some other little things done a couple of which I’m quite excited about.
Have some stainless coming up so I’m
Working on a set up to back purge and I’m looking forward to trying it.
New tool.
Turbo intake piece design is about complete , but next is to make it one piece .
Notches machined our for the bolts

And a little Venturi in the inside . Need to finish polishing

Yeah that is definitely quicker. Whos is that'?
I saw that someone had done that, Colin I think , and I was thinking damn there is a way faster way to do this.
But I downloaded fusion and I'm trying to learn the software so I can draw up and make things I need myself.
I was also curious on these indy turbos if it was possible to cut and weld a standard V-band flange on the exhaust side but I don't know enough about metallurgy or welding to take it on. So my manifold now is Indy turbo specific. If I can draw up or find a place to get a 20VT exhaust flange in stainless I'd like to start working on a design for a new manifold, as a spare or pre-emptively for my other car.
Oh and yes, grizzly is here in Bellingham . Reviews an this saw are great but some stuff I think is hit or miss. It's mostly woodworking tools there it seems like.

so.... Does anyone know. What's the longest throttle cable Audi made for a B2 car. The cable that came with my manifold is made to fit a C4. I need essentially a really short body but a really long cable. I may have to look at some pics of intake manifold and TB placement in the stock cars I guess. 1983 Coupe is probably actually not far off.
