Thanks. I’m still waiting on pricing from Quick Time. They are owned by Holley, and big companies don’t move very fast.
The good news is I may be buying 10 of them for the first run, so will have a few more available if anyone else wants one.

I'd be interested potentially, shoot me a PM. Trying to decide between the 5 cylinder and the 1.8t 20 valve though. Edited: Read back though and now it all depends on what engine I can find for cheap! A simple bell housing solution is much more attractive for me since I won't need to weld an adapter plate.

I'm going to build one first and test fit it in my car. I would guess I’ll have that done within a month, so by late July. Then i can start looking at a small production run if anyone is interested. I don’t know what the cost will be yet. Don’t hold me to it, but hoping in the $500-$600 range. It really depends on volume though.

Lots (hundreds?) of 07k engines are on eBay for around $400 shipped. I picked up mine locally for $250 complete with wire harness, ecu, and accessories. I also bought a forged crank for $100.

So you would want it welded, but without powder coating?

Wow...this is more and more tempting as I think about it. I think as soon as I finish this move I'l have to pick up this stuff..

Welded & no coating, yes. I can take care of that here. Good to know about the 07K's though, I've been looking around and i thought about buying a parts car but sounds like just a used engine is the best road to go down.

Thanks Danny. It's taking a lot longer than I expected to get the bellhousings made, but I'm making progress on designing a lot of the other pieces in the meantime.

Skimming this thread on Audi 07K swap prospects, it appears that proper oil sump geometry is an issue. My dumb questions: Would a composite oil sump made of carbon fiber or fiberglass work? It would need to sustain the heat and chemical exposure, but is it necessary to be as stiff as a cast aluminum oil sump? In other words, if all the sump has to do is act as a reservoir for hot oil, a composite oil pan would be realtively simple and cheap for a layman to fabricate.
Thoughts?

Here are a few other functions of the VW aluminum sump casting that any replacement would have to replicate:
- windage tray
- oil pickup mount
- timing chain guide mount
- structural mounts for the bellhousing ** thanks V2Rocket
I'm not sure how much the VW aluminum casting contributes structurally to the engine. It has a lot of webbing on it, but it's also bolted to a stout block of cast iron, so it seems pretty insignificant structurally to me.

also, a single rock strike to a brittle material like FG/CF would put all the oil on the outside
a lot of time "structural oil pans" means that the trans bolts to the oil pan as well as the engine block to make the assembly more rigid.
