Should've bought my car and turbo when I was going to sell it earlier this year! You would have had a meticulously cared for and designed setup. Oh well. I'm kinda glad I didn't sell it now. Still, I may sell mine in the future but hopefully not right away.

Yeah, probably. I mean heck, it ran and the motor didn't blow up. I haven't figured the wastegate location out yet and why the car never blew up but hey....I'm sure it will all work itself out.

the pics looked like the WG was installed after the wastegate hole in the turbo...which should work...it is just a weird design.

If it were installed after the turbo then there could be no bypass of the exhaust around the turbine and it would overboost every time. It must be between the up/down pipe and just not using the internal wastegate.

but if it were installed in the same plave an internal wastegate flapper was ...it could still be after the turbo. Does that make sense? It would just be a flapper that is a little further back b/c technically the hole that it looked like it was coming out of still is beforethe turbine. check out pics here You see...I think I am right...the wastegate would work correctly...no not ideal, but no worse off than an internal wastegate

There is a flaw in your thinking:
In an internal wastegate setup, the flap valve is connected to the diaphram with a connecting rod. The diaphram opens and the connecting rod moves, thus opening the flap valve. The flap valve seperates the "hot" side of the turbo to the downpipe oriface (forge the technical name). When the valve is open, the hot exhaust gasses bypass the turbine wheel, thus controlling boost.
I don't know what is behind that plate, but if it is the flap valve, do you really think that opening the external wastegate would allow the flap valve on the internal gate to open? I don't know, but why not simply use an internally gated design at that point? Not to mention, the downstream side of the wastegate vents to the air filter ... that's right ... it has no tubing and is completely open to under the hood. The more I think about it, the more I am dumbfounded by the design. I will definitely be getting the car in the garage this weekend and begin teardown and will document everything fully.
Also, those with turbo systems, where did you tap for your oil feed to the turbo?
As for the tubing routing, the part that I'm not pleased with is the routing of the IC piping between the IC outlet and the TB. Easily fixable. Like I said, I will shake down the bugs when I go to design the system for the Cougar. The Contour will be running right when I am done ... I glad to know that if I need the help, you guys are here!
And Tom ... STOP RUBBING IT IN! I wanted to buy the Tour when you had it for sale, but didn't have the money until this past July.

I can see what Stilov is saying. IF and only IF that little pipe connected to the external wastegate is actually INSIDE the stock hole in the turbine housing, THEN yes that wastegate setup would work. IF it is flush with the downpipe and not sealed to the hoel, then yes, it's doing nothing.
i.e. you CAN remove the sotck flapper, inserta tube into the wastegate hole in turbine housing and connect an aftermarket external wastegate to it. This MAY be what they did here, but until you reve that plate and see, you don't know.

And if that is the case, it's venting to under the hood, right next to the damn air filter

ya...stazi got what I was thinking...but fastcougar...you're right..why not use an internal then? I will be interested to hear what results you find.
