Have you talked to any manufacturers yet? A one-off, one piece Aluminum CNC part like that is going to be extremely costly to cut; if they are even willing to attempt it. Subtractive manufacturing is an entire different game than additive manufacturing.

Yes I gotten three quotes, one was $580, another was $1200 and one over seas was $200. Not sure which way im going. I have ordered from xometry before that was the $580 what was crazy anything after one was like $200 more. Guess I have no option if I want something custom that can be bought off the shelf.

If you were to simplify the design with minimal curves and minimal planes, the price will come down substantially.

Like square it up?

 

[Brian74]

Like square it up?

Eliminate excessive multi-axis curves and use minimal planes. Do you understand how a CNC process works? The less bit changes and axis planes required from the machine will lower the cost.

Yes some what understand not to much. Im assuming the more square the item is the easier it is. Also I guess the more square it is, it will take more material. Might try to tighten up the design and see if anyone else wants one. The more I order the cheaper it is.

 

[Brian74]

Basic subtractive manufacturing uses an x,y and depth (z) plane for each tooling cut. The less planes and tooling required to make the part, the cheaper. There are more expensive machines that can go beyond that, but they will ensure you're making part of their monthly machine payment for those parts.

What is it about the original housing that doesnt work?

My LSJ housing has two ports for the oil cooler which I have eliminate and will be using the heater core ports for the standalone oil cooler.

I want to switch as much as possible to AN fittings. So I expansion tank will have -12AN to the new housing. I will be threading the heater core nipples to install NPT x AN to run to the oil cooler.

So I can remove the rubber hose loops that I hate.

 

[David]

Fits like a charm

 

[David]

@Brian74 I gave it a shot, tried to make it as square as possible. I also added the driver side return coolant side for -20 ORB. In case in the future I want to switch my -16 AN to the proper
-20 hose.

In my opinion it looks ugly. What you guys think?

Check out JLCPCB.COM. They have 3d printing (metal and pa12 nylon), cnc and are cheaper than xometry

Will give them a try I was weird about 3d metal printing. Not sure if it would hold up to coolant, temperature and water tightness.

 

[David]

New design printed and it looks horrible well kind of. I do say the new design would flow coolant alot better.

Im pretty sure they do cnc as well. Its out of China and I use the cheapest shipping option. Takes a few weeks to get it.

 

[Brian74]

Is there any way you could just have the factory neck machined for the fittings and welded? That might be easier/cheaper in the long run.

 

[David]

I don't have patience, so I decided to install them and see if they fit.

I was going for this route first but run into some issues.
Not enough meat to make threads internally or externally. I was going to get weld bung and have a shop weld the rear oil nipples close and then weld AN bung for the expansion tank. Was not going to look as clean as if I created a new housing.

 

[David]

So I removed the heater core nipples and tapped them with ½" NPT. Will find a shop to get it anodized in black. Also was wondering what this cap is. Is it a bleeder port or was it used for something else on a different model?

 

[Rauq]

Assuming that's still an LSJ thermostat housing, I believe the cover you circled in red is where the block heater would go in Saab applications, and the threaded plug is where the turbo coolant feed would connect.

I believe L61/LAP/LE5/LNF thermostat housings put the coolant temp sensor in the thermostat housing, and the LNF also has a turbo coolant port on the thermostat housing.

Thank you, so pretty much non usable in the LSJ platform.
