Best guess is 1-2 weeks. Some of the parts they had to order from The Fatherland, so that pushed out completion by a bit.

Sadly no, so far all I've come up with is that CAD drawing that shows the dimensions of the OEM valve and mounting plate. The tricky parts to figure out are 1) can any of the aftermarket WGs be separated, i.e. remove the elbow from the spring/diaphragm/valve assembly? and 2) How long is the valve stem and what is it's movement range from open to closed? Machining an adapter isn't too hard, but the other part involves me buying a $350 WG and then proceeding to tear it apart and possibly destroy it...

Just buy something like this and save a few bucks.
I have a 44mm that just laying around for parts but will be to big for your application

My EBC setup arrived from DIYAutoTune yesterday. The setup is super easy. Since I still don't have the Tial adapter, I'm going to have to put the stock WG back on for now, hence the single-port configuration:
The kit comes with 1/8" barbed fittings, but my lines are 3/16", so I had to get a couple of new fittings
All installed, along with a plug for the unused port.
And mounted on the old airbag sensor bracket in a vibration-resistant clamp.
There are only 2 wires to connect. One goes to a switched 12V source, the other to the COM port on the back of the ECU. Easy!

Interestingly, they applied ceramic coating to the exhaust housing even though I'd already had that done. So now there's two layers of coating on the housing, plus a turbo blanket. If this doesn't keep down the underhood temps, nothing will! Add in the coating on the CHRA, the new heatshields, exhaust coating, and exhaust wrap, and this thing should be as insulated as humanly possible :up:

Have you gone to a front mount intercooler?
