Turbo sizing

Looking to put a single turbo on a 5.7 hemi. Totally stock engine, contemplating a 6.1 cam/springs and possibly pushrods by recommendation of PWR racing and a few other things I read on forums (lxforums, etc). No idea on gains from this cam, just know it is recommended for forced induction purposes. No other modifications on the engine besides the later valve covers and coil packs. It will be run by an aftermarket ecm, megasquirt in all likely hood and I intend to run it with a flex fuel sensor to utilize E85. My goal is 11.50-11.99's in the quarter with a car built to turn on high performance street tires, not dot slicks. According to the majority of 1/4 mile calculators out there, one specifically being my favorite (link, requires weight in KG), it should take around 550 hp to pull this off. While the power will be easy, the launch will not, but I think it can be done. It has a fair amount of tire, 315/35/R17, with a RMS triangulated 4-link, but it's obviously not gonna hook like a drag car. Only 25.7" tall tire in the rear. I intend to combat this with aggressive boost control options offered by megasquirt (boost by gear/rpm/etc), launch control options (multi-staged rev limiters) and traction control options (vss, rpm, etc). I think the car can be made to have a reasonable, consistent launch. The 60' can be made up for down the track by the turbo. The transmission I'm running does have some relatively low rpm drops, 3600rpms or so coming into 2nd and 3rd but I think the 600+ ft.lbs of torque these engines seem to be putting out at that rpm range should pull through it just fine. I will either be running 2.76's or 2.93's, the first gear of the transmission is very steep at 3.753 requiring this. The accompanying benefit is a cruise rpm of 1800-2000 rpms @ 70 mph, hopefully lending to some outstanding mpg results. I expect the car to weigh in at no more than 3500lbs with me in it in full street trim. Mustang aluminum spare tire, full tank of gas, the whole deal.

I have another thread running here in the forced induction section but it seems like this would get some more useful input in this subforum. I'd highly recommend you look at it if you don't mind, it details a variety of different details about my plans. I'm really just looking for assistance on sizing the turbo, cold and hot side piping, and just general experience people have with this situation.

As always, thanks for any input.
