That ought to be interesting. Good Luck!
BOOST LEAK!!!!!

Time to order some good quality silicon hoses and fab some aluminum/SS/or even just some painted steel tubing and ditch the plastic setup. I've seen a few 6.0L Ford diesels blow the factory plastic pipe.

Would there be a heat sink issue with metal tubing? Would larger pipes from turbo to intercooler be of any benefit?

Also, 4DR, would a fluid intercooler using the A/C system be a possible choice or is this what is being referred to as a water to air intercooler? Believe A/C compressor turns off automatically during WOT.
Air/water has a fluid encased intercooler that cools the charge. The fluid is then pumped to and cooled by a heat exchanger up front of the radiator. What you're referring to with the ac is a Killer Chiller that uses the ac system to cool the fluid instead of just a radient heat exchanger.
The pipes question depends on underhood temps. If the temps underhood are higher than boost temps, then the aluminum pipes would absorb heat. If the boost temps are higher, then the pipes would radiate heat.

Not complete apples to apples, but on my diesel truck I noticed (as many others have) an increase in lag when increasing the charge pipes from the stock 3" to 3.5" like that of the Banks intercooler on my truck. Many will run the larger Banks intercooler with reducers to keep the charge pipe diameter.

I think 110+ degrees out doesn't help, probably work where it's not so hot, I don't know what the Livernois big turbo guys have done to accommodate their higher boost.

Either of you look to see if Samco offers a silicone hose/tube that fits in this area (where the tear/failure was)?
They make pretty quality stuff.
If not, what are the measurements & I'll ask.

That makes sense. I have a Pontiac friend who was the lead contract metallurgical engineer on the EB Engine project a few years back. He told me recently that the reason for the small exhaust manifolds is to create higher velocity to the turbos, spinning them up quicker. Guess the same issue applies to the pressurized air.
For those who wonder why the 3.7 version isn't turbo'd, he said Ford tried that, and the stroke length caused failures as early as 100 mi.
Another interesting thing he told me is that he has again been given the lead position from his firm, to work with Ford on their revised 2015 EB engines. He has seen the design changes and called them revolutionary.... Plan is to have boost at idle, making the EB 3.5 even more responsive. Unfortunately couldn't detail any of this under his employment agreement. He was very excited!
There is a fine line on the hot side that you have to walk. You need to have enough back pressure to get the chargers spooled, but keep it low enough not to send the heads sky high. The waste gates help bleed off that pressure at higher rpms, but at the same time, that is wasted energy.
The way to combat that is where I'm guessing your buddy was hinting at, which would be to hang some variable geometry turbos on there which will allow the computer to control the size of the exhaust housing a/r by adjusting a set of fins in the turbine housing. Here is how it looks on my truck. I went from a stock 58mm compressor to a 64.7mm wheel with almost zero change in lag...

He intimated that the head design combined with turbo intake will move turbos almost to the heads.
He also said he has seen the 2014 EB Pickup engine, but not sure if it will change much. Big deal appears to be in 2015 for our cars.
His G8 has a Livernois 418 and he is thinking about turbo'ing it. Our phone contact came about because of my 09' G8 rattling sound coming from the bell housing. Know him from forums and at G8 Natl. Conv.
Hopefully G8 issue will be low tranny fluid. Checking tomorrow (GM 6 speed autos are very hard to get accurate fluid fills). If that doesn't fix, the tranny and stall converter come out. Only noticeable in park, and when engine is off throttle.

Just in case someone else upgrades their turbo you will need a 1.75 to 1.5" silicone reducer like this:

You'll also need some new clamps due to the stock pipe has a plastic ring on the top part of the pipe and an attached clamp on the bottom.
I've attached some pictures of the before/after
