I didn't read the complete thread, but here's what I know:
Having worked at TDR in the past and having installed many intercooler kits, I can mostly tell you what works.
There are many TDR customers tracking their stacked heat exchanger setup reliably with a 37mm PWR/Koyo radiator setup in 100*+ heat. You'll see even better results if you seal the TDR plastic ducting.
An oil cooler is absolutely necessary! The solution that we had came up with, and I still use, is mounting the oil cooler off of the steering rack so that it is parallel to the ground. I made sure that it is above the steering rack and not the lowest point on the car. We then cut a duct out of the factory bellypan and used L-brackets to keep the shape of the duct in tact. One thing I learned, though, is don't use a Tru-cool style oil cooler. It was extremely inefficient compared to the Setrab, Earl's and Mocal coolers.
The problems that I can see with running the TSE radiator on the TDR intercooler setup is the fact that the TDR intercooler uses modified radiator brackets to lower and move the radiator back. When running stock fans on a 37mm radiator, sometimes it is necessary to trim the shroud to clear the sway bar. It's absolutely necessary to trim them running the RB sway bar brace.
With the TSE radiator being so thick, I don't know if it's possible to make it all fit with the sway bar and front core support limitations. Someone test it and report back.
Andrew knows his ****. The biggest factors boil down to how hard you drive, how much boost you run and ambient temps.
