Deciding on parts for my turbo setup

[Rock3tman]

just guessing, I'd say  the donor Saab was sometime from late '80s thru '90s - - sorry i can't be more precise.   

I'll try to post a photo later today.

That looks great! I'll have to peak around some yards and see what is out there!

Quick question: What size piping was that saab pipe?

Because i'm looking online here, and the flange appears to only have a 1.90" diameter hole. I'm wondering how big of an output the vnt exhaust housing is anyway?

Is there any advantage to running a 2.5" downpipe on a turbo that only has a 1.90" output flange? Or should I just run 2" downpipe?

after poking around I think I can pick one of these up and use it to fab a return line (i can't find a stock vnt return line for cheaper than about 70 bucks and I'm just going to have to tear it to pieces anyway). I was thinking with that and a few feet of braided -10 an oil hose I'd be in business. Anybody know if this will work?

Then have a 10an fitting welded to the oil pan?

I think your plan for using -10AN fittings will work well;  I used a stock TD oil pan, then had a short section of 16mm steel tubing welded to a male JIC fitting on one end and a compression fitting to mimic stock on the lower end.   Then I attached a short braided stainless sheathed teflon hose with female JIC fitting on lower end and a open top end slid over an aluminum barbed fitting bolted to the VNT-15 oil drain area.

Excellent ! I think I'm getting closer with all this. Is there any reason I should use jic fittings or barbed fittings over the an fittings? Seems the aN hose and fittings are abundant on fleabay and good prices.

Thinking about doing this for the pan. Is there enough clearance for this ? I'm trying to eliminate as much welding as possible. As welding is going to cost me!

The AN are mostly aluminum and IMHO junk. They are the exact same threads as JIC Exactly a 37.5 degree flare and the number designates how many 16ths of an inch it is. Example an-10 or JIC-10 is a 5/8 or 10/16 sized hose. I like the JIC as the steel ones I have are very reusable.

I think the pan idea would work. I welded mine as I didn't want the chance of vibrations letting it come loose. One major thing I recommend is using a 90 out of the pan. On mkii angled approx. to the freeze plug by #4.

Perfect! You're the man That's exactly the input I needed. I'm still such a newbie with all this fabrication stuff. Theory I understand but how to actually build custom pieces I'm working on.

 I looked up jic fittings and it seems hydraulic surplus stores sell them very reasonably. And I'd only need like 2. I'll be sure to take pictures of all of this together once I get it going.

Also found a huge 2" pipe nipple at work that may get jb welded onto a plate for my intake adapter.
