Don't think it will be that hard to do. As of right now, I'm leaning towards the single turbo, cause like 5.0 in OK said, "they just sound cool!"...lol and not many Stangs in my area are turbocharged.
Just because Magaizines say you'll be pulling X amount of horses, doesn't mean once you put the turbocharger on your car, it will pull that power.
Fabbing up the pipping is not as easy as you may think. Been there Done that and let me tell you, it will get OLD FAST. Its amazing when you look at your car and say, the turbocharger will fit here FINE. Guess what, it never works out that way.
Heres my experience.
I decided on a Single T-63E Turbocharger. I decided to turn the shorty headers around and mount them on the opposite heads. I then would run a pipe from the passenger side header, down infront of the front sway bar and then back up to the driver side. The turbo was to be mounted where the battery was located. I then would run the exhaust out under the drivers side header, between the steering shaft and to a Y connector so I could retain the factory dual exhaust look.
Sounds easy right?
Making the pipe that goes from the passenger side to the turbo's inlet Y pipe was not easy. You're better off putting a flex pipe in the middle of it so that when you go bolting it up, if your slightly off, it will bolt up. If it was a straight piece like I had and barely off, it wouldn't align correctly after a couple heat cycles (When you removed it, it wouldn't go back on).
Also routing the downpipe wasn't as easy as I thought it was going to be. This was a NIGHTMARE.
Also the cold side wasn't easy also. I had it routed from the turbo, to a front mounted intercooler, then from the intercooler to the BOV, MAF Meter, then to the throttlebody. I got so frustrated with the piping from the intercooler to the throttlebody, I ended up just calling Cartech Racing and had them BUILD me one. Working in tight spaces its hard to measure the correct angles you need.
After I got the Cold side/hot side done, I discovered another nasty flaw in my thinking about a week later. Driving down the road, the car just died. No power.
Popping the hood, I discovered that my Turbocharger placement was great for accessibility and keeping the stock accessories, however if you put the turbocharger where the stock location of the battery is, make sure you put heat shields around all your wiring. The Turbocharger radiated enough heat, to make a fuselink soft and melted away part of the insulation. The wire then touched the inner fender and you can guess what happened (Burned fuselink)
Like I said, if you think its going to be easy, you're in for a real education.
I'm not trying to discourage you from a Turbocharger, just saying, its not as easy as the magazines say.
