Garrett makes awesome turbos, and so to Schwitzer, holset, borg/warner, turbonetics, etc. t3/t4 is a popular combo for a twins set-up.
Honestly, I can speculate that you should get "this" or "that"... but it could be a trial and error process finding one that suits you... Both HTT and II (that I mentioned above) are stand up companies. Talk to them.. figure out which one of them you trust the most... buy a turbo... try it out... they'll work with you on "tuning" it to your tastes.
Buying turbo's is like a suit off the rack vs. one that has been tailored to you. There's a LOT that goes into turbo design and selection.

Also, let me address the "they just wanna make a sale"...
I've yet to hear of II or HTT pushing or pressuring people. They love power and going fast. They're both good companies and I belive that you will be glad you talked with either one.

The problem with single turbo set ups are that if you get one big enough to handle the heat of racing or pulling the spool up lag makes it hard for daily driving. That's why the twin set ups, it get's rid of the lag on the bottom end and gives you the extra exhaust room on the top end.
The new compromise to this in the singles is the variable geometery turbo's that are starting to hit the market. They cost a little more then a normal single, but don't have all the complicated plumbing and tuning of a twin set up so they come out a little cheaper then twins.
After I post the following statement, I'm gonna take a whip to myself for sayin it. One of the big success stories of the variable geometry is the one that is marketed by banks. They used the same turbo as comes on our Cummins as the platform and changed the fins and few of the inner workings to make it into a variable type unit.

The injector question is a loaded one with alot of factors that can effect a common rail.52psig is way to my boost for the stock turbo at that point you are just shoving in hot air.I would suggest a larger turbo . Depending on what you are using the truck for maby compounds would be a thought. The stock head gasket on a common rail is amazing but if you are going to to try and push beyond 50psig consistantly head studs are in order.The camshafts are lacking in the hpcr motors for nox emissions control the cam timing has been retarded . If money is no object I would suggest an aftermarket cam to help spool up a larger turbo. Hope the helps good luck

Just from experience I would becareful of the ATS compounds

By the way I am an HTT dealer Call HTT and talk to the tech department and they can help you find the turbo best suited for your needs.These guys are honest to a fault.

Some of our sponsors might have kits.
I know that Rip sells the kits (as well as a bunch of other individual parts), but I think they are for second gens:
