wow, you guys are feeding this guy with all sorts of screwed information, lol..
One question.. have any of the above poster's ACTUALLY done R&D on a rear mounted 5.0 setup FIRST HAND?
Last time I checked the volume of a cylinder is pi*r^2*h. Assuming you use 2.5 inch intercooler piping and run that along the outside of he H pipe to the front of the engine, that is roughly 5 feet for each side. [3.14*1.5625*60 inches of pipe]*2 since there 2 pipes=588.75 cubic inches. This extra volume translates to pressure drop and a loss of velocity. Throttle response will suffer as a result of the extra volume.
Basic physics will tell you that heat will add velocity so mounting the turbos further away from the heads will reduce heat available to the turbos. Therefore inhibiting the ability to spool the turbos.
The oiling concerns are absolutely a fact. The drain on the turbos can not be gravity induced since the turbos are on the bottom of the car. You will need to suck the oil out as well as feed them.
External wastegates have a diaphragm that is most often vacuum operated although you can use pressure to actuate the wastegate like in Tials. You will not find the necessary vacuum/pressure source next to the gas tank. A good option is a vacuum block which I already mentioned.
The extra charge piping, bracing, and remote oiling system translates to weight which is the last thing you want to add to the car. Simplifying the system by mounting the turbos under the hood above the oil pan would reduce weight.
You might think that you are saving money by avoiding the purchase of turbo manifolds, but that initial cost incentive will be lost when you consider the price of AN lines, the remote reservoir, pumps, T-bolt clamps, miles of charge piping, and bracing required.
Actually this applies to all cars not just Mustangs, but any
RESEARCH you do will tell you that it is not worth
DEVELOPING a remote mounted turbo setup. I NEVER said that remote mounted setups can not work, they are just not worth the hassle since it is easier and cheaper to run turbos under the hood.
Really, the only advantage I can find in a remote system is relieving the under hood temperatures. Personally, I would rather spend less money while going faster with the turbo under the hood and just deal with the added heat compromise.
